Radiator Stop-Leak To The Rescue

A month or so ago, I had some serious truck problems. I was losing coolant rather quickly, and I couldn't figure out where it was going. As a result of that, I was also seeing the temperature gauge climb. A coolant leak is slightly disturbing if you see it dripping out somewhere, but at least you know what to fix. When it is disappearing in the engine somewhere, that is a major bad sign. It often means a bad gasket or a cracked head or block. This almost always means a big repair bill.

I was looking at a similar situation, as it appeared that one of the gaskets was leaking. Hoping to avoid that major repair, a mechanic friend of mine recommended that I try a stop-leak product. Now, I have never been a big fan of engine additives and liquid repair products. Ones I have tried in the past have performed marginally, or seemed to make no difference at all. But, in this case, I thought, "I might as well try it, and if it doesn't work, I'm not out much, and the engine will have to be torn apart anyway."

So, I was told to try Justice Brothers Radiator Stop-Leak. It is easy to use, and only takes about 5 minutes to put in the car. After dumping it in, I drove the truck a couple of times, and didn't see any definitive improvement. BUT, on the third or fourth drive, I noticed that it wasn't heating up like it had been. After the drive, I carefully removed the radiator cap, and it was still full! Since then, I haven't had any trouble with the truck heating up, and I haven't noticed significant coolant loss.

I have to hand it to Justice Brothers, as it seems that they have a decent product. I don't expect the fix to last forever, but any postponement of that repair I can get, I'll take.
If you want to try it for yourself, you can find out more about it at Justice Brothers. It runs about $8 or so, and you can find it at many major auto parts stores.

UPDATE: If you are running a vehicle where damage to the radiator or cooling system is likely, such as driving off-road or racing, you may want to add this product BEFORE you head out. If you develop a hole while you are out running around, it can seal it up immediately, and save you some trouble.
