A small radiator leak can cause antifreeze to leak on your 1998 Chevy Lumina when there are not any spots on the ground. A pinhole in a hose can also cause this.
you likely have a leaking heater core. Is this on the inside of the vehicle? if so then it defintately is a leaking heater core
had a 95 3.1L V6 Lumina that would lose AF as well. Maybe your intake manifold gasket or head gasket are going bad. If there is unusual stuff on the oil fil cap or dipstick you have a gasket leak.
have system pressure tested to observe leak
Upper intake manifold plenum leak/crack most likely. If its blowing out coolant then you probably have a bad head gasket.
most likely heater core leaking
Dexcool is recommended.
Pentosin Type G12.
For a 1989 lumina, it's about 6.25 inches from the ground to the lowest part on the car.
add to coolant recovery tank!!!
A 50/50 mix of water and antifreeze
If the pump is leaking or noisy then assume it is failing.
Sounds like head gasket is leaking
i had this problem the intake manifol gasket is blowed
Oil pump driveshaft (also referred to as distributor) o-ring is bad. Replace, and oil will stop leaking there.
A 50/50 diluted mixture of DEX-COOL. I would recommend Havoline. You can get that at any parts store.
because it is old and has begun to leak
There are several things that can cause your Chevy Lumina fan to not work properly. The most common cause is a bad ground wire. Check the ground wire and make sure it is tight and free of corrosion.
Please clarify your question. Is the plug on top of the engine or the car? Is it leaking water, gasoline, or oil?
You're Leaking Gas into your oil
Could be low on coolant.
My 98 Lumina had the same issue. Found out that the Coolant opening that connects the engine block to the timing cover leaks! This is just behind the belt tensioner. Have to remove the timing cover and in my case, I used High-Temp gasket maker, because the machine surfaces were not flat causing this area to leak. I would suggest not to use a gasket, but instead use the High-Temp silicone! ~Steve
I have a 1990 3.1 and what it turned out to be was the head gasket was leaking now it runs fine
Mix half and half with distilled water (can buy pre-mixed) and pour into the overflow bottle up to the full mark.
