Its a 4x4 2002 Grand Cherokee.Crank the car and let it run... no signs of coolant leaking. Look the motor up down and over. Let it cool and few hours later there is a puddle. Get under there and between the bell housing and motor there are coolant drops. I think there is a leak. But that can only be If there is a freeze plugs on the back side of the motor. I've been trying to find pictures to confirm this.

If i need to take the transmission out is there any special tools that I need to get the trans and transfer case to come out? I'm very mechanic inclined but I'm not going to spend 100 bucks for a tool I'll only use once. Its a 4x4 2002 Grand Cherokee .

Thanks guys

X2 on posting the Engine info.
I believe if you had a freeze plug issue it would leak while the engine is running. Do a cooling system pressure test to find any leaks.

if i were you depending on the amount of miles i would replace the intake gasket. you have to relize that the back of the motor is the hottest area as air can't get to it and cool it down. chevy's are notorious for blowing intake gasket on the rear of the motor because of this issue i put a cowl hood on my silverado when i had it cuz i got of replacing them

If it's a 4.0 liter there is a frost plug on the back of the head.Might as well pull the head check all parts swap head gasket and replace all frost plugs.g/l

I have the same issue with a leaky freeze plug. It just so happens that this plug is located on the back of the head just inches from the firewall. I am pretty handy but wasn't ready to commit to pulling the engine or dropping the tranny. The leak was quite small but enough to cause me some problems with overheating. I was prepared to do a bit of cheating. I stumbled across a post about "water-weld" by JB Weld. It's an epoxy putty that dries rock hard in 1 hour. I cleaned the affected area very well and then cleaned it again. I used steel wool, emery cloth and throttle body cleaner on a clean rag. I was able to get a mirror back there to check it. It was good to go. I applied the "water-weld" and one hour later no leak. Drove it again today with no leaks. So far so good. I'll keep you all posted.
