Hey all first post just registered.
So my 99 grand prix gtp with 233,xxx miles started loosing coolant then ran a tad hot about a month ago so i just refilled the overflow tank and it was all good but in the last week or two the engine heats up quickly and runs pretty hot. After running awhile there is the sweet smell of anti freeze outside the car, not too strong though. The heat is taking longer than usual to warm up as well. It also has started running kind of rough when in idle, Im not sure if that is related to this or not.
I just changed my oil and did not notice anything in there, nothing milky, watery, ect. I cannot detect any leaks either, tried putting cardboard down, no leaks underneath the engine. Only thing I could thing of is it is coming out my tail pipe?
The check engine light just came on so I am going to get that read now, also going to check the radiator to see if there is any antifreeze actually in there or if the antifreeze is just staying in the overflow tank and not getting to the radiator.
Any ideas or advice would be great thanks
Luke
