water pump

[Talonmom]

So upset. Car was completely () rebuilt just needed tranny. Ran fantastic until last 2km home. It now warms up, warm air inside then put in gear, blows cold air and antifreeze (quite a bit) comes out the bottom (driver side/over flow). Off to try and find a water pump. Replacing rad cap (which was corroded), and thermostat first but don't think that it is this simple. We did recheck tranny stuff and don't think overdrive is working. Possibly a connection (button?) underneath gear shifter itself? Thanks for all your replys, it is helping a lot.

Pushing coolant when you bring it off idle sounds like a poor sealing head gasket if it does it after the new properly sealing rad cap.

Other wise, rad caps are notorious for leaking coolant into the overflow bottle and then over filling it.. air in place of coolant will settle in the heater core. Flushing it all out, sealing the system up good, and making sure there are no air pockets should fix that issue.

O/D button is in the shifter handle, wires run out the bottom to a plug under the console.
