Hi All;

I am a newbie here. Can anyone tell me why there is a pool of coolant on top of the intake manifold? It is a 1991 Delta 88. i tightened all the hose clamps. I can't figure this out.
Also can someone tell me where the coolant fan switch is. I like to change it to a lower temperature one so the cooling fans turns on sooner. Thanks

How much coolant are we talking about? Is the thermostat neck gasket leaking? If the car has a temperature gauge, has the engine been running hotter than normal?
