How do you add coolant to Pontiac sunfire when low light comes on?

Answer 1

Probably depends on the year, but normally the same. Most GMs use Dexcool, which is held in a tank to the left of the engine, about mid way from the front to back of the engine bay. Be sure to add dexcool (oragne colour) if its already the type in the there (the coolant currently in the tank would already be orange) which it most likely is. Its probably the easiest to buy the pre-mixed coolant, many coolants come unmixed and need a 1:1 ratio of water to coolant. So, a qt of coolant and a qt of water. Best to stick with the premixed for simplicity. Just be sure to read the directions. Anyway, best to do this when your engine is cold, then fill the coolant up to the line on the front of the tank reading reading "Full Cold". This can be diffcult to see, the marker is embosed and you'd be able to feel it. As for filling, if your having a hard time see where the level in the tank is, stop filling it and gently shake it, it is much easier to see the movement of the fluid and judge the level from there. Once you fill to the marker, seal the cap and that's about all there is to it.
