1990 8v AT geo tracker, For some odd reason went back out and cranked vehicle and it idled down properly. It was not racing at all . Popped the hood because I noticed a little steam. It appears that I am loosing alittle water but the drip is under the throttle body, I cannot see exactly where it is coming from. Also saw some bubbling out of a hole on the back side of the throttle body. Need help on this.
Check the hoses that connect and torque of the fasteners on intake manifold and all around it and the throttle body. The manifold has pressurised coolant flowing thru it, so if they are loose it will leak.
If tightening things up doesn't stop the leak, then you have a bad gasket probably. Relatively easy to fix.
Between the head of the engine and the intake manifold
There is also a gasket between the manifold and the thermostat cover. That could be leaking and then running over to where the TB is.
There are like a dozen or so gaskets, fasteners, or pipes on that part of the engine that could leak coolant. I'd say let it dry out good and then run it up to temp. and then looks with a flashlight and dab at it with a paper towel to try to find the origin of the leak.
