I've had an ongoing coolant leak that I am unable to diagnose. It's leaking from the bellhousing area. This is a new one for me. Leaks approx 3xdrops per day. Is there a freeze plug at the rear of the engine or something similiar that can cause this?

It's not the heater hoses. Checked with a mirror. They are dry. There is no coolant in the the oil (I checked the dipstick). It's not the H2O pump... as I just replaced this.

$0.02 on this matter appreciated. Pics included.

 

I just had this problem well kinda. Mine is an automatic, it was leaking from the water pump, then down to the top of the oil pan, by the bolts that hold the pan in place, then all that way towards the rear of the vehicle, then to the transmission. So it traveled quite a way from the original leak location. So I hope this helps with the process of elimination, and you find your problem.

 

Appreciate the reply, but that's not my prob. I thought the same....and changed the water pump last week. The leak has not diminished...and it's definitely NOT leaking from the water pump now. :(

 

Mine is also doing that, mine is coming from a leaking head gasket. Lots of.stuff in the way and it can be hard to see. Hope that's not your problem, or you are under warranty.

 

Head gasket was going to be my next suggestion, I too hope it is not that. How many miles do you have, and do you have any noticable decrease in coolant level in overflow?

 

Look at the HVAC drain. See if it is wet with coolant. That would indicate the heater core or its hose connections.

 

Have 62K miles on the Jeep right now. The coolant overflow will decrease , but it takes several weeks to really notice it.

 

What I have done on other vehicles when I had a slight coolant leak from a gasket in any number of areas was to try what a really good mechanic recommended before tearing something down that would be costly and complicated. That was to add the "powdered" stop leak that comes in a small tube and almost looks like grahite. I've done that on three occasions on vehicles and it has worked every time without any problems. The repair lasted for years and past after the vehicles were sold. Never had a problem. Whether you decide to go that route or not is your decision, but I can tell you that it worked and saved me a lot of cash too include the aggravation of tearing down an engine, which can cause other issues.

 

Appreciate the response. I found some Prestone "stop leak" and added that tonight. It looked like Chocolate Milk when pouring it into the system It's been raining today, so will have to wait till it's dry out to see if it worked (underside of the car is soaked).

Seems like a toital redneck fix, but if it works...then a well spent $2.89

 

Hopefully it works for you. If it doesn't work try the powdered stop leak. That's the stuff that was recommended and worked for me. The first time I used it I didn't think it would work and that it was what you refered to, but it worked and saved a huge repair bill with no after effects. I've seen the Prestone liquid but never tried it.
