    Race Caddy losing coolant and making noise

    Just got a call from the guy where the car was dropped off. The caddy he says is making some sort of noise on the far right side (standing at bumper) of the engine, and it is leaking coolant. Is it possible that the water pump just went kaboom?

    That's where the water pump is.

    I think we are going to stud the engine whether it needs it or not (assuming it does) so when we drop it we will replace the water pump and thermostat as well.

    Water pump or 3-rib pump belt tensioner. Keep the OEM thermostat because all the engine controls are set to operate around the design coolant temperature : about 200 degrees at 16 psi.

    The OEM thermostat starts at 188 and is fully open at 206.
