Probably because you have a blown head gasket. Get a compression check done to be sure.
A 1997 Chevy Cavalier uses a standard 50/50 mix of antifreeze coolant and water. This keeps the engine from overheating and from freezing in the winter.
The GM vehicles use the DexCool anti-freeze. There is a replacement type of antifreeze that can be used in GM vehicles but you cannot mix them with the DexCool. To change to another type of antifreeze the cooling system should be completely flushed of the old coolant. I would advise keeping the same coolant as the manufacturer provides
The coolant temp sensor for a 1977 Camry is important to the engine running properly. The sensor sends a signal to the computer to keep the air/ fuel mix correct.
Engine coolant is what I'm assuming you are talking about. Engine coolant is a mix of water and etholyn glycol (antifreeze). It pulls heat away from your engine block that builds up from the friction of moving parts. The coolant mix allows the coolant to get cold to a point and not freeze because of the etholyn glycol. It is also not good to put straight antifreeze into your engine because antifreeze does not have as much cooling potential as water antifreeze mix. Also if you have just antifreeze in your engine the antifreeze will boil at a much lower temperature than a mix of aproxamalty 50/50.
You could in an emergency, but do not mix Dexcool with any other types of coolant.
Drain radiatorRe-fill with a 50/50 mix of antifreeze and waterRE-fill slowly to prevent an air lockRun vehicle to normal operating temperature with heater on and recheck coolant level
Antifreeze should be a 50/50 mix with water. If you bought pure coolant, mix with water. If you bought premix (already 50/50) pour in straight.
Bad head gasket Cracked head Cracked block
50 50 coolant is what i use- would suggest no more han a 60 40 mix.
An Spirit engine doesnt use any spacific type of coolant, as long as its a 50/50 mix.
be sure to not mix the different colours(red&Green) they Aren't compatiable with each other.if in doubt drain then flush system then completely renew the coolant.
Oil and coolant should NEVER mix in an automobile. Can you be a bit more descriptive in your question? Im led to believe there is something wrong with your vehicle. I agree with him, if you have what you call a mix of coolant and oil on the valve cover you have an internal coolant leak you need to get looked ASAP. Oil and coolant do not mix anywhere, it's like if you put oil and water in a jar and shake it, it seems to "mix" but it really doesn't and it will separate when left alone. If you get too much coolant in the oil, it will take away the lubricating quality of the oil and it will ruin the engine.
