1998 mustang gt coolant leak

While I had the front end on a ramp to change the oil, I noticed coolant leaking. Alot of coolant is leaking down between the transmission and oil pan. But I can't tell where the coolant is actually coming from.

    Would that also cause coolant to come out the tailpipe? Thanks samson-1

    Hey BobC6402, that is interesting, I changed the thermostat a while ago and noticed the leak got worse after that. But I could never find the leak. I will have to to start her up again and see if I can trace the leak better. Did you have any water coming out the tailpipes? Thanks for your help!

I just had the same problem. Ford design the intake manifold with plastic water crossover which cracks. The coolant will leak onto the top of the block and and then down the back of the engine. This intake design is a known defect and was ocvered under by Ford for 7 years past the date of mfg. The crack either is in the crossover or the thermostat housing. I happed on this when I found the same leak and traced it back to the thermostat housing. I changed the thermostat, but it leaked worse. You can pickup a aftermarket for $200 and it's about 4-6 hr job to replace.

Probably the intake manifold gasket.

    That would probably be much more serious, maybe a cracked block.

2002 sunfire ecotec blowing out oil from front of engine

The front of engine is usually where the serpentine belt is located. The side of the engine toward the front of vehicle is different. I'm not trying to split hairs, Just trying to understand? Is it coming out in the area of the belt?
When you had it on the ramps, was the engine running? One thought is too much crankcase pressure?
There is, the oil filter could leak, oil pan gasket, head gasket. Is there oil in the coolant or coolant in the oil? It's tough to find a leak if it isn't leaking when you check it.

Coolent went down and oil level shot up, what do i do-drain the oil, its leaking oil real fast now right after an oil change

Drain the oil and check for coolant, if there is coolant present, you have a head-gasket problem. You may also notice sweet smelling exhaust because of the coolant leaking into the cylinders.

Leaking Coolant

I believe the other one is underneath the motor mount, which means you will have to remove the mount of you need access to it..

Suggest you check your engine oil, it should be either light brown if just replaced, and black if you have over 30K miles on it.

If the oil is brown like in color, maybe you have an intake manifold leak and anti freeze is getting into the motor oil (Bad Bad) Check for leaks in the heater core inside the car and see if the rugs are wet.

Check radiator for discoloration in the fin areas and tank areas. Finally check your radiator cap, maybe its defective and you loose antifreeze through the overflow.
