Low coolant level in 2000 Grand Prix GT

Low coolant level light keeps coming on. I fill the coolant and it keeps going down about an inch below where it was . The rad doesn't leak, and heat guage is fine. Where is the fluid going?

    The intake manifold had a small leak in it. Took it to the garage and had it replaced for $472.00

    Have you checked your oil to see if there is evidence of coolant on the dipstick?


    Also, have checked the radiator cap?  Overflow bottle cap?

I had the same problem this winter. The head gaskets were blown, took the block apart and replaced all the gaskets. Cost about 300 - 400 in parts and took one full day to finish with 3 men who aren't particularly experts but who aren't rookies to say the least.

Goodluck

If you aren't seeing and/or smelling any coolant then you could have a small leak in your head gasket.  If this is the case that would mean the coolant is mixing with your oil.  I don't know how long this has been going on for you but I would suggest pulling your oil dipstick and seeing if you can see any water dropplets on the stick.  If you are losing coolant and can't see it I would be very careful because a blown head gasket can lead to some very expensive engine repair.  If you can't find the leak I would take the car to a mechanic and have them check it out for you.  Good luck.  thanks for an honest rating and for using FixYa!

Sometimes full is not full...If you don't add any, does it stay an inch low or does it continue to go down?
also check under the car after being parked overnight. any coolant on the ground will give you a clue as to any small leaks.

2006 jeep grand Cherokee limited if the radiator overflow jug is empty will it cause the transmission temp light to come on


I would say it is possible an overheated engine which is not coolling the transmission can trigger a lot of lights. Many transmissons are heated and coolled by a line which goes to the radiator of the engine cooling system.

How do i replace the coolant in my 96 dodge caravan after i flush the system


Make sure all the drains are closed, start filling the rad and allow the coolant time to drain down, then fill again. Keep filling the rad unit it no longer drains down, just make sure to stop filling it when the level in the rad is just barely visible when looking down inside it. Now fill the overflow bottle to the lowest level mark. Start the car and turn you heater on to full heat. Let it warm up to proper temp, may/may not need to put more in rad. Keep an eye on the level in the rad it will expand and may overflow, if it looks like it will overflow use yout tester to remove some fluid. Once you see the coolant flowing throug the rad wait a few minutes, then put the rad cap on. Let it run a few more minutes to get the rest of the air out, then drive like normal. Check the fluid level in the overflow bottle (engine cold) over the next few days fill to proper level as needed.

How to flush coolant on 2004 grand prix


  • Move your badass w-body (a.k.a. Pontiac Grand Prix) to a level area and set the parking brake. Pop the hood and touch the radiator. If it's warm let it cool before you continue.
  • Twist the radiator cap one full turn (Remember to be careful because even when radiators are cool they can still erupt coolant)
  • Place any type of container (bucket [but has to be able to hold 2 gallons]) underneath the radiator and blow the drain plug. (The drain plug on your Grand Prix is on the driver's side bottom of the radiator facing the engine.)
  • Loosen the drain plug and let the old coolant to drain completely. (You may need a wrench to loosen the drain plug)
  • Dispose the old coolant in a sealable container (The coolant is very toxic to people and pets, so you gotta be careful)
  • Shut the radiator drain plug and fill the radiator with water.
  • Run car for a little bit and repeat the process again. (Let car cool, and drain water)
  • Close the drain plug and fill the radiator with fresh coolant until it's about an inch from overflowing. (DO NOT USE ORANGE DEX COOLANT IT IS HARMFUL FOR YOUR HEADGAKETS) You will need 3 gallons of coolant (SE, GT, GT1, GT2, GTP, GTP Comp G.) and 4 for the GXP model. Be sure to check the drain plug for any leakage.
  • Start your car and turn the heating system to high. Allow the car to keep running until the cooling fan turns on twice. After that happens, switch off the engine and check the coolant level. If it went down, add more coolant. If not, put the radiator cap back on and close the hood.

I let my car heat up to get frost of window for about fifteen minutes. When I went out the frost was still on window and no heat coming from dash and car was overheating. I shut it off, let it cool down...


Start with engine cool, remove rad cap, start engine and turn heater on. Top up rad level and Let engine run until it get's up to normal operating temperature with cap off and add coolant as you see it go down. Watch in rad for coolant to start moving quicker, once gauge gets close to normal temperature, indicating that thermostat has opened. Wait until you see that 2 or 3 times, then top up and install rad cap. Top up coolant return bottle to proper level . You'll want to keep a close eye on coolant return bottle level for next little while. If coolant got that low in the first place, you have a leak somewhere that will have to be found.

1998 grand prix low coolant light keeps coming on thermostat,hoses,radaitor,and intake gaskits have been replaced...the radaitor is full everytime i check it


If the engine is running well and not running hot, chances are that the coolant level sensor has failed. You can either replace it or ignore the warning light and just check the level as "routine maintenance"
while checking your oil and other fluids weekly as every good vehicle owner does and has done since there were cars to drive.

LOW COOLANT LIGHT COMES ON SOMETIMES AND TEMP GUAGE SHOWS ENGINE GOING TO OVERHEAT. HEATER GETS COLD. IS IT THE THERMOSTAT?


There may be a thermostat problem, but your symtoms indicate low coolant level. When coolant is too low, it will not circulate, so you get no heat in car, and the coolant remaining in engine block overheats because no cool fluid coming in.
You need to fill the system up properly then look for leaks.
With cold engine, open radiator cap. Fill with antifreeze directly in radiator. Start engine, top up rad if level drops. Put heat control on Hot. Fan on low, heat on high. Gently rev engine and top up rad as needed. IF as engine heats up, it starts kicking fuild violently out of radiator, then the thermostat is bad. if not, then recap radiator, top up overflow bottle and you're done. Look under car for any sign of leaks. Steady dripping indicates a leak, then address that.

When the car is just running the temp. gage reads normal after it warms up..where it should be ..the heater will then put out hot air as it should...but as soon as I take off ..the indicator needle drops...


First thing to check would be your coolant level in return bottle and radiator when engine is cool. Remove rad cap, and start engine and turn heater on, and see if level in rad goes down, or is low and if yes, top it up while engine running. Allow engine to get up to normal operating temperature and top up as needed while watching it. Allow rad fan to come on and off a couple of times then put rad cap back on, then top up return bottle to proper level. If level is up and you don't need to add any, then I'd start by changing thermostat. Be sure when re-filling system after changing thermostat, to start car and turn heater on while re-filling, and allow plenty of time with cap off to bleed any air out of system. I normally allow fan to come on and off 2 or 3 times to be sure. Then put rad cap back on and top up return bottle to proper level. Something else to keep in mind is that if the coolant level was fairly low when you first check it, is why was it low? Keep an eye for any coolant dripping down on driveway, or engine, and be sure to check return bottle level often for next few days in case of leak in system.

Where is the coolent sensor on a 1993 Buick Regal? My coolant light on my car comes on while driving. The car isn" low in coolent and doesn"t over heat.


Depending on the engine that you have most of the coolant level sensors are mounted in the radatior about a foot down below the fill cap. They often had problems with these sensors getting debris on the end's of them causing a false reading. What your looking for is a black box about an inch and a half square and about 3/4 inch thick .you can try to remove it and clean but the best way is just to replace
