LEAKING COOLANT.

My 07 unlimited is leaking anti-freeze coolant from my jeep somewhere. I think it is around the intake manifold where the hoses connect. Has anyone else noticed this problem. It just started a couple of weeks ago and I can smell it if my jeep runs about a 1/2 hr., but I can't see where it is leaking exactly.

Check the thermostat. My 07 does the same, since around September. Drips down by pump, so looks like pump is leaking. Mine is above.

I had to replace my intake manifold gaskets around 28k miles. I'm told the leaking is a common problem with this engine.

Mine was doing that.the other day when I was changing the oil I was gonna clean the throttle body also.I noticed the thermostat housing had a seapage around it.when i grabbed it to check it was so loose it actually moved in my hand.I tightened the two 10mm bolts and no more leak.

You say you replaced your gasket. Did you replace it and was it simple. Do you have any schematics or PDF,s that I might look be able to look at?
