The other day I noticed steam coming from under the hood so I drove the car home watching the temp gauge. I got it home with out it over heating. When I opened the hood I could hear steam and water escaping from somewhere behind the motor on the passenger side. I checked the hoses for the heater core and they looked good. I could not see where it was coming from. I had to add about a gallon of water to the system. There was no water in the oil or oil in the water. The car has not lost any power. The water is dripping off of the exhaust cross over on the passenger side. Is this a head gasket problem or is there a freeze plug or something else I should be looking for?

Thanks for the help

Theres a bunch of hoses in the back. If you have the FSM (you can download it from this site) look up the bypass hose #3. About 6 months ago most of my hoses started to leak back there from all the temp changes and when I would stop at a light, steam would roll out of the hood.

Also check the intake plenum. Mine was leaking at the water neck up front.

 

Tubbyfatty you were right on target. It was the hose coming out of the intake manifold. Thanks for pointing me in the right direction.

Thank You
