Question about 1999 Chevrolet Monte Carlo

''Low coolant'' warning daily

I keep having to add a half gallon of water twice a day (to and from work). I work 35 mile from work but am careful to keep a close eye on my temp gage to make sure it doesn't overheat. Looked for the source of the leak but couldn't find anything leaking. Engines running great so I'm sure I dont have a blown gasget problem (no water leaking out of the exhalst). Can the problem be with the Thermastat?

I will assume this is a 3.1 or 3.4 liter engine. if so, youre probably dealing with a leaking intake manifold gasket. to confirm, using flashlite or good straght beam, ck under upper intake of engine on drivers side. (under throttlebody) you will see a pool of coolant (orange-ish). it is somewhat of a large job and costs around $600, depending on shop. replace thermostat also while in there.

The best thing for you to do is to take it to a shop and have it pressure tested, before you blow a head gasket.

Im trying to replace my coolant and I'm not sure how much to put in. It's the 4.3 L v6 in a 1988 GMC c1500


Don't know the exact amount but around 2-2 and a half gallon. Do this use one gallon straight antifreeze and one gallon water run engine for a few minutes then turn off. Check level and top off radiator. Add appropriate level to side tank

How many gallons of coolant does the northstar engine hold?


Coolant should be mixed in most cases to a 50% concentration, meaning one gallon of undiluted coolant will provide two gallons of diluted coolant. Most engines will hold 2-3 gallons of coolant mix. I normally purchase two gallons of undiluted coolant. I pour the first gallon of undiluted coolant into the radiator, then fill the empty bottle with water and add that to the radiator as well to make it a 50% mix.. Then, I pour half the second bottle of undiluted coolant into the empty coolant bottle, and then top both off with water to make two gallons of 50% mix. I then add coolant to the radiator as needed until full, keeping the remainder for topping off later as air purges itself form the system.

You're going to need to visually inspect for leaks and if no external leaks are evident I suspect your head gaskets are leaking again - check oil for coolant in oil - it will look milky

Where to add coolant for radiator on a 95 vw jetta?


Add Coolant to spherical reservoir at right rear of engine compartment as viewed from front. If it is low the coolant gauge flashing light will warn you of a low condition.

ABS and coolant are unrelated unless there is a problem with the ECM (engine control module) or instrument panel. Is the red coolant warning sign for coolant level or temperature?

With ABS if there is any failure with any brake electronic component (sensor, motor, or fluid level etc) the ABS will shut down completely and flash the light. If the light is on or flashing the ABS is non functioning.

I need better information on the coolant and ABS to give better information.
