Water pump or coolant tube behind engine oring. Fill with water and pressure test if the leak is not visible without pressure.

Check the coolant hoses that go to the throttle body.

Good bye


The small hoses go from the intake manifold to the throttle body and from the throttle body to the black steel return pipe. Steam by the alt is usually the weep hole in the water pump telling you it is ready for a change.

There are two heater hose sized hoses also on the tranny side of the throttle body into the manifold. The bypass hose from the thermostat housing and the hot heater hose going to the heater. There is a small freeze plug in the bottom of the manifold that can rust out also. When I lived in SoCal 35 years ago people ran just water in their cooling systems because it never freezes, but the freeze plugs rust out!

Just got off the phone with kingthursday.
NOBODY saw that one coming. :shake
I'll let him explain. But I believe he and z34-5speed are currently by-passing the throttle body for now. :ermm:

That is where the temp sender for the computer is located, better figure that out so it will run right.
