My 240 has a coolant leak, so I brought it to the dealer twice. The first time they said it was just a small hose that needed to be replaced, it didn't stop it so the next day I brought it back and they said they forgot to tighten a cap. It's still leaking (I see a small puddle about the size of a saucer after it has been sitting for a while). Any ideas? The dealer couldn't seem to figure it out and I've already been there twice. The car is 20 years old with 200k miles, so things like this will happen, I just want to nip it in the bud before major damage occurs. Any help is greatly appreciated.

 

well, where's it leaking out of ?

lots of candidates. if you can't tell, clean the engine, then drive it a day or two and look for new seepage.

I've had coolant leaks from a weak head gasket below the #3 and #4 exhaust ports, I've had coolant leaks from where the water pump joins the head (makes a little puddle on the body of the water pump), and of course from various hoses. oh, and my son had his heater core blow, that was fun, he was way up a forest dirt road in the snow, at twilight.
