Repair of a radiator of a stove Mercedes 190
If you have financial problems, you can try to repair the radiator. In our case, the plastic burst to the left of the radiator and a leak appeared.
The crack is clearly visible in the photo.
To check the radiator for leaks, you need to install the radiator on a car without a casing and start the engine. In a few minutes you will understand where the flow is.
In our case, I flared the leaky side and removed the plastic. I covered the crack with sealant, it can also be welded. Next, I assembled the radiator and installed the radiator without a casing in the cabin. Checked for leaks and put everything back together.
If you decide to solder, then I want to recommend a hot air soldering station, which I assembled myself. Welded according to this scheme. The drill beveled the crack and cut it out. Next, I cut out the strip I needed from a suitable plastic. I will use it as an electrode. Using hot air, I heat up our plastic electrode until it melts to fill the crack. I have a soldering iron in my other hand while I fill in the crack and smooth and seal the edges. If it is difficult for someone to understand in words, look for a video on how to repair car bumpers.
