It weakens the effect of the coolant.
The 1994 Pontiac Grand Prix can use any SAE certified coolant. In normal climates, the coolant can be mixed half-and-half with water.
If you are loosing coolant from the radiator and you have an abnormal amount of white smoke from tailpipe after vehicle is at normal operating temperature. This may be an indication of a bad head gasket. Or if you notice coolant getting mixed with the engine oil or engine oil getting mixed with the coolant. Also a sign of a bad head gasket.
The coolant is water mixed with antifreeze (35-50%).
( YES ) you can buy premixed engine coolant ( antifreeze mixed with water ) or concentrated antifreeze
If this happens only when engine is cold it is a normal condition If this hasppens when engine is at normal operating temperature it may be a sign of head gasket leakage Check to see if oil is getting into coolant or coolant getting mixed with engine oil
Wrong mixture make sure you have pre diluted/mixed coolant/antifreeze.
Anti-freeze is a coolant that should be mixed 50/50 with water
Coolant from radiator? Run engine to normal operating temperature -remove transmission dipstick and let a drop fall on hot part of engine, oil will "smoke" coolant will "sizzle" If so a bad radiator allow transmission fluid from cooler lines to get mixed with engine coolant
you always should mix coolant with water if it is full coolant. most coolant today says 50/50 on the package and is pre mixed in which case no, but if it is straight 100% coolant, yes mix with water.
Coolant mixed with a little air circulating thru the heater core. Check the coolant level in the reservoir.
Antifreeze is coolant. Coolant goes in the radiator. There is one type that is already mixed with water, and a type that isn't. Either one works, you just have to put half water and half coolant in the non mixed one.
Coolant container will say if it is pre-mixed or full strength. If full strenght, mix it 50/50 with water. Pre-mixed coolant can be added "as-is"
