My 3rd gen GXE is starting to overheat frequently. Ive checked the more obvious choices and replaced them, it wsa fine for a few weeks and now it starting to over heat again.
Ive already installed, a brand new thermostat, brand new water pump and gasket, both upper and lower radiator hoses, and i am running straight antifreeze due to the extreme heat in Vegas.
What else can it be?!
Ive been looking through my book on the car and it says that it could possibly be the radiator itself or even the radiator cap not allowing the system to pressurize or even the fans
has this happened to n e one else?!
i need n e help that can be offered.
overheating in Vegas is notgood at all.
Please help
Thanx

Re: Maxima Overheating (DragonMaxima)
My understanding was always that water cools better than antifreeze, so summer mixtures work best as 50/50 or higher (in favor of water). Also, you could try some Redline Water Wetter.
Do the electric fans come on at all (they're loud, you should be able to hear them). Start the car and leave it sitting for a couple minutes. The fans should come on after it doesn't move anywhere for a minute.
What kind of shape is your radiator in? It may just be that it's full of gunk...get a good look at it (hard to do, I know) and run to the car wash and spray it off with the sprayer. There is a picture floating around the Q forum of someone's removed radiator...it's probably 40% open and 60% jammed full of junk. Your car is old enough that this could be a factor in the overheating. Be careful when cleaning the radiator with high pressure sprayers...car wash sprayers should be safe, but if the pressure is too high you could bend the fins and decrease the cooling effectiveness even further.

Re: Maxima Overheating (MinisterofDOOM)
A used radiator is not a new radiator.............every year a radiator declines in effectiveness from bent and corroded fins and the degradation of the rubber foam seal to direct air.
New OEM PARTS can return cooling to new OEM STANDARDS.
Common aftermarket copies can be as bad as 90% effective brand new!

Re: Maxima Overheating (Q45tech)
yesterday i ordered a new koyo radiator for my car, so when that gets here hopefully the issues will end.
I was originally running 50/50, but like tha tit seemed to get hotter faster, thats why i ran full antifreeze.
i even did mostly water and some antifreeze plus water wetter, but it still heated up fast.
it doesnt help thats its like a thousand degrees still.
as for the fans i know they work, the passenger side blade spin, but the drive side blade doesnt, on the driver side fan the motor does work and is spinning, when i gave it a close look i could see that the fan was not atached to the motor, so the motor is just spinnin on its own without the blade, all these issues will be addressed as soon as the new radiator arrives.
lets hops there are no other issues.

The Koyo is in!! Took all of like 20min to do. The car seems ok now, i drove it around after the The Koyo was put it and it seems fine.
The original radiator i took out had to have a lot of **** in it, it seemed to weight like 30lbs it was crazy heavy.
im gonna put some new fans on it too be on the safe side, that and get some Purple Ice.
Now on to better mor expensive modifications!!!
