Volvo B5244T3 engine

One of the popular Volvo engines installed on S60, XC70, S80 and others. B5244T3 is a turbocharged power unit, manufactured in 2000. Reliable enough, but, like any engine, eventually needs maintenance and repair.

Engine description

The working volume of the B5244T3 is 2,4 liters. The 5-cylinder unit is powered by gasoline. The compression ratio is 9 units. Able to develop power up to 200 hp. With. thanks to the turbine and intercooling. The exhaust system is VVT.

Engine from Volvo

B5244T3 is installed under the hood in front, transversely. The cylinder arrangement is in-line, which is considered by experts as the best solution for such a motor. There are 4 valves per cylinder, so the engine is 20 valves. Fuel consumption on the example of the Volvo V70 XC 2,4 T is 10,5-11,3 liters of fuel per 100 km in the combined cycle. Acceleration time - 8,6-9 seconds.

An interesting review from the owner of a 80 Volvo S2008 equipped with this engine. Here is what he writes: “This is an in-line twenty-valve five with an intercooler and a low-pressure turbine with a boost of 0,4, if I'm not mistaken. Already from 1800 rpm, a torque of 285 Nm is available. Traction on the bottoms is just super, fantastic! Do not feel turbo pits, pickups. The motor runs stably, smoothly, convincingly. The location is transverse, equipped with a timing belt, automatic valve compensators are provided. Oil consumption is about 100 grams per 1000 kilometers, which is fine for a turbo engine.”

Maintainability

The B5244T3 is a Swedish engine, so knee repairs won't work here. This is not some Japanese motor for which a pair of wrenches and horned wrenches is enough for maintenance. With Volvo, this will not work, you need a variety of ratchets, torxes, heads of special sizes, pullers. In general, everything is like the Germans - a lot of tricky, complex knots. For example, connecting a generator or ramp and a fuel line. To disconnect these nodes, you will need the help of at least three people and a lot of tools, including a powerful flashlight, pliers, and an awl.

Now about prices:

• original air filter - about 1500 rubles;
• oil filter, VIC - about 300 rubles.

The official dealer in Moscow is Bilprime, in Krasnodar - Musa Motors.

Common types of work on Volvo B5244T3

But what work usually needs to be done on this engine:

• flushing nozzles;
• overhaul;
• oil change;
• replacement of the timing belt and drive belts;
• preheater repair;
• cleaning the EGR valve;
• throttle body cleaning;
• cleaning of the ventilation system and crankcase gases.

Overhaul

Major repairs are always expensive, but inevitable. Therefore, it is desirable to postpone its term as long as possible. Here's why, as a rule, the overhaul period comes ahead of time:

• low-quality oil was poured or the lubricant was not replaced for a long time;
• refueled low-grade gasoline;
• the standard maintenance procedure was not observed;
• foreign objects got into the timing drive cavity, causing various mechanical breakdowns.

Overhaul always begins with primary diagnostics, then disassembly, troubleshooting, and replacement of defective parts are carried out. The final stage is assembly and adjustment, verification of operation.

Engine overhaul

Oil

One of the most popular maintenance procedures is an oil change. Many volvovodov carry out this operation on their own. According to the regulations of the Swedish manufacturer, this should be done every 20 thousand km or once a year. Given the Russian operating conditions - twice a year or every 10 thousand kilometers.

The oil recommended by the manufacturer is Castrol. It contains all the necessary additives that provide consistently high performance in all operating modes of the lubrication cycle.

The following are situations that make it necessary to change the lubricant even earlier:

• periodic operation of the car in the city, traffic jams;
• frequent launches in severe frosts, in the morning;
• regular movement with revolutions above 3000 per minute;
• prolonged idling.

Belts

It is impossible to underestimate the timely replacement of belts. It is these parts that drive the attachments and the timing drive itself. Additional components include a generator, compressor, pump. Under ideal conditions, accessory belts should function for at least 5 years, but in practice they become unusable much earlier. Most often, belts deteriorate from prolonged exposure to reagents, the Russian climate, and regular loads.

The timing belt is a separate issue. This unit is a key link in the reliable and proper operation of the engine, because it transmits torque from the crankshaft to the cooling system pump and valve camshafts. According to the manufacturer, the timing belt should be replaced at least 120 thousand kilometers, but in reality it is recommended to halve or even triple this period.

Signs of destruction of belts are easy to determine:

• extraneous noise from the engine compartment, reminiscent of a whistle;
• cracks on the belt during visual inspection.

Starting heater

As a rule, starting heaters of two companies are installed on the B5244T3 engine: Webasto and Eberspeacher. Over time, these devices may require repair, as carbon deposits accumulate inside the boiler, the fan deteriorates, the nozzle assembly or glow plug fails.

1. Carbon deposits are formed due to the combustion of low-quality fuel. The malfunction is repaired by complete disassembly of the boiler, mechanical cleaning and assembly.
2. The fan is designed to force air into the boiler, displacing exhaust gases from there. If it fails, the heater will not start. The problem is solved by replacing the fan assembly with the impeller and drive, and in some cases, the assembly with the control module.
3. The injectors inject fuel into the combustion chamber. If the process is carried out incorrectly, gasoline simply fills the boiler, strong smoke and pops appear in the muffler. On Volvo, the ceramic part of the nozzles most often suffers, but they change as an assembly (except for the XC90 - a separate replacement is provided here).
4. The glow plug tends to burn out. In this case, the control module detects an electrical malfunction - a short circuit or an open circuit. Therefore, the pre-launch device does not start. The solution is to replace the spark plug.

B5244T3 engine replacement

A large number of scoring, a drop in compression in one or more cylinders, misfiring are signs of a decrepit engine that needs to be overhauled or replaced. In this case, if you carry out restoration, you will have to re-sleeve. However, in some cases this is more expensive than replacing it with a contract option. If you're lucky, you can bargain for a motor with low mileage for only 50-60 thousand rubles.

Be sure to replace the gaskets, seals, bolts, clamps and studs during the procedure. Naturally, you will have to change the oil and filters. Special attention will need to be paid to the generator - if necessary, replace the bearings, freewheel. Check the thermostat, which tends to crack on the old engine. As a rule, the old radiator is also subject to replacement, which may not withstand the power of the new engine. The Nissens model is perfect.

big uncle	Good people, Volvo gurus, tell me what is the difference between the B5234T and B5244T motors. I understand that the different volume of 2400 and 2300 due to which the difference. piston diameter or stroke?
Michel	If we are talking about engines for S/V70 1997-2000, then according to the catalog that I found, the difference is this: Engine capacity 2319 cm3 - 2435 cm3 Power 250 hp. – 170hp Torque 350/2400n*m-220/4700n*m Turbocharging yes/no Cylinder diameter 81mm-83mm Piston stroke 90mm-90mm Compression ratio 8.5-10.3
big uncle	Yes, you are absolutely right, these years, I have a V70. The motor was 2400 dead, is it possible to install a motor from 850 with a volume of 2300 on it?
Groom	at the expense of interchangeability, you need to look specifically
So Ra	Strange. According to VIN, my B5244T beats like 193 hp. and data like this Engine location: Front, transverse
NordHest	You have a low-pressure turbine, and in the previous comparison of high pressure, with high pressure, Erki seemed to be walking.
So Ra	As far as I remember, with a high-pressure turbine, the power is about 240 horses - this is the B5234T. He is a T5 for 2.3 liters. B5244T - Low pressure turbine, 193 horses, 2,4 liters. And on an engine of 170 horses, in principle, there is no turbine. Neither high nor low. If I'm not confused.
Michel	yes, there is one in the catalog, only in the table of contents is the volume 2.5 193 hp, and 2.4 170 hp so in the catalog
big uncle	That's right, I just have 2,4 193 horses with a low pressure impeller, but he died, or rather, it is necessary to change the cylinder block. Is there a good engine for 2,3?!!!
Buyan	no 2.3 is good, they are all half dead, it's much easier to find 2.4 or 2.5 at last
Pilot	right where 2.3 good will come from such years ......
Zhelovek	and religion does not allow capital?
Lavinochka	here, as it were, there was a specific question, and not whether he is alive or half-dead, or vice versa from 70 to 850, and what difficulties will you have to face? I'm also interested in this. And if you replace only the block, and leave the head, will it roll or not?
Sergo	Capitalize??! Interesting! And how much money will it cost you? And where can you find inserts?
NordHest	so my B5254T died (more precisely, a block). I don’t know what to do now ... What can I put in return?
Whack	any motor from 92 to 2000, whether from 850 ki or from S70, and the outboard seems to be completely identical throughout these years !!
NordHest	hinged okay ... And how will the brains take it all? how will the motor work? Brains are obviously tuned to certain characteristics of the engine?
Finn	there are no such years not 2.3 not 2.4 good. piston 300 thousand and skiff, in principle, motors are rubbish, which cannot be said about engines from 99 and newer. if you change 23 to 24 and vice versa, then you need to make a complex replacement - the motor computer is a turbo, both collectors and some other little things I don’t remember right away. if you don’t replace all the main nodes, you will kill the engine.
Whack	Naturally, the motor in combination with brains will swap!
NordHest	there is an opinion that the immobilizer will not start if the brains are rearranged? This is how you need to rape the engine in order to kill the piston to 300? On the same forum there were absolutely opposite opinions regarding motors. I have, if not for the groove eaten by gases from above ... everything else is ideal.
big uncle	the motor was installed, everything was fine and tidy, as it should be, you just need to buy a Magenti Marelli throttle valve. So I have a head, a flywheel, a crankshaft with a piston, coils, cover bolts for sale from an old engine. B5244T
Sound	Does anyone happen to have waveforms of the valve timing on a 70 XC2002 5 cylinder B5244T3 engine? Either dpkv and dprv, sync. Thanks in advance!
Vladimir	There is Px with XC70, but there is like a 2.5 motor. By that Px, as it were, the release was late, but when rearranging a tooth earlier, the Check on the DPRV lit up.
Misha	Why an oscillogram?
Sound	just a synchronization error shows and starts for a long time, the engine is noisy.
Sound	The exhaust shaft was two teeth wrong, too late. The oscillogram helped to install correctly.
Antokha Moscow	I ran into a problem, sometimes when starting the engine starts to triple, a reduced engine performance 41 error appears on the on-board vehicle. I take off the clamps for 15 minutes and everything works again for about three or four weeks. There was a similar trouble about two years ago, then the problem was in a broken bracket shaft crank sensor, but now it’s not clear what. Of course, it would be possible to go for diagnostics, but I’m afraid they won’t find anything
Denis	there is such a misfortune, the crankshaft sensor, for some reason “it’s kind of magnetized” for these motors, it works for 4-6 years, and then the brain starts to soar, I had such a problem on the 960th, (sensors are the same) either troil, or that from the second, then from the tenth time it started. Eventually it stopped working altogether. In short, I changed the contacts in the connector in places, and woo ale, -20 on the street, started up from half a poke, on a rather planted battery, because. tried to start a week, in the winter.
Antokha Moscow	I also sin on him. And because of the mass air flow sensor, there can’t be such garbage?
Denis	The air flow sensor is responsible for the flow rate, my connector is screwing up, the speed rises and, accordingly, the flow rate, but it doesn’t bother me. The camshaft sensor may also be in the brain, or rather the connector, literally a week ago I encountered this problem, the green wire (+) burned out after washing the engine, the diagnostics in both cases did not show errors, or not related to the sensors, but without DPKV it consumed gasoline at about 30k . I mean it's a performance related bug.
