SOURCE: Low Coolant warning Light

on the passenger side of the radiator there should be a coolant level sensor several inches from the top facing the engine. they are known for plugging up with sludge or just going bad. They connect with a metal retaining clip around the outside edge and are easy to change

Not an intrigue, sorry. run over anything lately? A pinched cooler line could cause this. Or maybe just an old, gummy transmission.

SOURCE: I have a 2000 silhouette. the coolant level low

Bleed the air out of the coolant system,and add more coolant,to radiator,and reservoir,and make sure the cooling fans are coming on,if the low coolant light stays on,remove the low coolant light sensor,and clean it off,it is located on passengers side in the radiator,it has a wire clip you have to remove,and dont loose it,after cleaning it,put the clip back on the sensor,and push the sensor back in the hole.

1998 grand prix gtp stalls when coming to a stop and low coolant light stays on but car does not run hot.


Stalls when coming to a stop- have idle control motor checked as this may possibly be the cause.
Low coolant light stays on- there is a low coolant sensor located on the radiator on the passenger side. They are known to go bad on these models, this is a possible cause. Have your mechanic take a look at it.

98 grand prix 3.8 non-supercharge starts but wont stay running have to keep foot on gas pedal to stay running blows out white some trough the exhaust. no coolant in oil what is causing this


If it is blowing thick white smoke that is coolant. You can lose a head gasket in places where only coolant passages go through so you don't always get oil/coolant mixing when this happens. Take the radiator cap off and see if air bubbles through it. You can also try pulling the spark plugs to see if one or more looks really clean.

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.

YOU NEED TO REPLACE THE UPPER INTAKE MANIFOLD. ALSO, YOU WILL NEED TO REPLACE THE LOWER INTAKE MANIFOLD GASKETS. THIS IS A MANUFACTURING FLAW. THE PLASTIC INTAKE CRACKS CAUSING AN INTERNAL COOLANT LEAK. YOU CAN RESEARCH THIS ON LINE.

I got a 1997 pontiac grand prix gtp coupe. the low coolant light constantly flashes. the coolant fluids are full. i just bought it and i am a little frustrated.


Sometimes the float in the low coolant sensor gets stuck.Find where the electrical connector is on the overflow tank and lightly tap on this area.This might dislodge it,if its stuck.Good Luck!!!
