How do you add coolant to a Pontiac Grand Prix?

How to Change Coolant in a Pontiac Grand Prix

1. Raise the hood of the Grand Prix and make sure that the engine has cooled completely.
2. Place a bucket or drain pan under the drain plug on the radiator.
3. Raise the car enough to remove the jack stands.
4. Add a 50-50 mix of distilled water and anti-freeze to the radiator.

Is Dexcool bad for your engine?

Ten years after General Motors began using Dex-Cool as an antifreeze in most of its cars and light trucks, GM car and truck owners continue to complain that the coolant corrodes and clogs radiators and radiator caps, erodes water pumps, rots radiator hoses, causes chronic overheating and engine damage while leading to …

Why is Dexcool so bad?

Cooling systems that use Dexcool exhibit more acid buildup and rust in the system when the coolant level gets low and oxygen is allowed to enter the system. The acid eats away at head gaskets and intake gaskets. Rust builds up in the system, inhibiting coolant flow, which causes overheating.

Can I replace Dexcool with Prestone?

Yes, you can replace Dexcool with Prestone in the yellow bottle. There is very little difference between the two, besides the color (Prestone is greenish yellow).

What happens if you dont use Dex-cool?

If the DEXCOOL is not completely removed from the cooling system, harmful interaction between coolants can cause major issues. Mixing DEXCOOL with standard/regular antifreeze often causes a jelling of the cooling system which causes a loser of cooling capacity which leads to major over heating.

Is Dexcool good antifreeze?

For a couple decades now, GM has used a type of coolant known as Dex-Cool. Despite not being called antifreeze, it still accomplishes the same task, so you don’t have to worry about replacing Dex-Cool for the winter months or anything like that. Firstly, Dex-Cool and traditional anti-freeze don’t mix well.

Can I use universal coolant instead of Dexcool?

Can I Use Universal Coolant Instead Of Dexcool? Yes. But make sure when you take your vehicle to a shop, have the universal antifreeze depleted completely on the off chance that you have blended in different coolants.

What happens if you mix universal coolant with Dexcool?

Mixing universal with Dexcool antifreeze will almost guarantee the mixture will gel and sludge in your cooling system. The green and orange coolants do not mix. When mixed together they form a gel-like substance that stops coolant flow and consequently the engine overheats.

Can you mix Dexcool 50/50 antifreeze?

Do not mix Dex-Cool with regular anti-freeze! Dex-Cool is a specially formulated GM coolant which will not mix with traditional coolants, and was used in various GM applications up through the 2004 model year.

Does the color of antifreeze matter?

The truth is, color is not a reliable predictor for what type of coolant you have. For example, OAT coolants are usually orange, yellow, red or purple. Then the older IAT coolant is green. Coolants that manufacturers sell can confuse matters even more, like Honda’s blue coolant.

What’s the difference between pink and green coolant?

The key difference between red and green antifreeze is that red antifreeze lasts longer than green antifreeze. An antifreeze contains ethylene glycol and propylene glycol as the bases. It often can last five years or 150,000 miles. So it’s a better antifreeze to use.

Is using universal coolant bad?

Generally, all makes all models universal antifreeze is 96% ethylene glycol and just 2 to 5% inhibitors. So mixing different types of antifreeze coolants or add the wrong antifreeze coolant can actually CAUSE corrosion, pitting of water pump, rust formation in radiator and total cooling system degradation.

Can I mix Prestone with Toyota coolant?

The two mix OK (Prestone Green also contains phosphate corrosion inhibitors, so it’s not like it’s incompatible, although generally you’d prefer one or the other (my main objection to mixing the two is you get a “brown” antifreeze, which looks too much like rust in the antifreeze for my tastes).

Is Prestone coolant good for Toyota?

Prestone 50/50 Prediluted Antifreeze/Coolant for Toyota vehicles is specially formulated for use in Toyota®, Lexus®, and Scion® vehicles**. Prestone Antifreeze/Coolant for Toyota Vehicles will not void warranty, works with ANY color antifreeze and is compatible with Asian-based POAT technologies.
