coolant leak

I just bought a 93 YJ. It has a 2.5L motor. The truck is quite rough but does run. I am concerned that it losing coolant where the engine and transmission come together. Is this a sign of something serious? Didi I buy big problem?

Any advice or information would be appreciated.

Thanks!

why do you think it's losing coolant there? is there coolant in the oil?

It drips from that area. It leaks when it is not running too. I find small puddles after it sits for a couple of days. I have checked the hoses but haven't found a leak. My heater doesn't blow cold either. Do you think it could be my heater core (that is the side the leak is on).

Thanks

it could be. hopefully one of the more knowledgeable folks will show up and give a better answer.

I've only had my YJ for about 4 weeks.

Check you puddle and see if it's just water. If so, it's probably condensation. Whenever you run A/C or defrost your core passes the condensate down a line that's just to the passenger side of centerline, right at the firewall area.

If you aren't "missing" any coolant, and it's just water on the floor, that's your culprit.

This is definately coolant. The air on this unit truck isn't connected. Do you think it could be a head gasket?

there is a freeze plug on the back of the head above the trans that hold coolant. I have seen quite a few jeeps have it leak, You might be able to see it with a mirror.

That would account for the coolant in that area, but what a place for a freeze plug. Can it be changed without pulling the engine?

you will have to pull the head off and take it to a machine shop to replace the plug. Make sure you replace the head gasket and torque it properly. I would also have them clean the head good.

No problem just whatever you do make sure you torque the heads it is critical. And go ahead and replace your intake/manifold exhaust gaskets as well.
