1998 Chevrolet Lumina base model.

I have had the vehicle examined by two mechanics. Both did a pressure test. OK. One wanted to rip apart the front of the engine and try to find the leak. Another provided a new radiator cap. Neither could find source of leak upon looking. Car, on lift, is in a level position.

Looks like anti-freeze leak as it evaporates after a few days on pavement.

On level ground there is no leaking of any fluids.

I park on a slight incline in paved driveway. If front of car is facing up it leaks. If car is facing down, it does not leak.

No temperature warning lights have come on. Temperature stays steady. Fluid in radiator is full and reserve tank is at full line/mark. Thermostat was changed a few months ago.

Even when car is facing uphill, I cannot see any leaking fluids. I do see drops on bottom of metal cross bar near front of engine or right side of car just behind right front wheel/tire. The metal cross bar has droplets but I cannot find where the fluid is coming from.

It stumps me.

 

Thanks for looking. I think I found it. I bought some GUNK went to car wash and washed area completely and let dry.

It is sneaky. It drips from water pump onto fan belt then drips to metal cross bar on bottom of engine.

When driving to mechanic, car is hot and most evaporates so one cannot see as drip is gone.

I think I need a new water pump.

 

good...intakes are much higher
