Question about 1998 Chevrolet Lumina

1 Answer

I have coolant leaking from underneath my 1998 Chevrolet Lumina

I have coolant leaking from underneath the car.

Specifically, the coolant is coming through a plate with four holes on it underneath the car; this plate is located near the side of the engine with the drive pullies.

I thought that possibly the water pump or water pump gasket is leaking. However, I am not sure where the water pump is on this vehicle. I would expect the water pump to be on the bottom, but I can see no evidence that this is the case (like say a radiator hose).

There is a radiator hose fitted onto a nipple on one of the components on the very top of the engine. Is this the water pump? If so, is it possible for it to leak from the inside, then down through that plate? If it is not possible, where would this coolant be coming from?

By the way, the plate with four holes in it is not referenced in either manual I have checked as a part, so I am not sure what it is for.

Water pump is located in the center of the left side. If you remove the plate you mentioned, you can probably see it. It is probably the source of the leak. The seals are prone to go bad in them.

Coolant leaks

Hi, Andre. That sounds like the water pump's seals have given out. If you can see the water pump, look on the bottom of it for coolant leaking. If that's where it's coming from, you'll have to replace the water pump. On your Lumina, the pump is either driven by the serpentine belt, or by the timing belt. You need to look at a repair manual for your car.

My 1998 chevy lumina won't start right away and

The cooling system shouldn't be losing much coolant.

If you're putting in coolant regularly
If you're seeing slick oil in the coolant
If you're hearing noise in the engine while driving

You may have a crack in your engine block and your engine isn't being lubricated properly anymore. This will cause noise and leaks, make a motor run really rough and cause rough starting.

I suggest you bring your vehicle in for a coolant system pressure test and a chassis leak check. This should be a free service from any auto shop that wants your money for repairs.

Spark plugs usually degrade your performance slowly and don't make noise while doing it unless in extreme cases.

Good luck!

1999 Chevrolet Lumina is leaking a red, sweet smelling fluid. It has puddled in the spare tire wheel well. Any ideas

Sounds like coolant, Cars use a red coolant now days. The only other red is trans fluid.
