Besides the obvious answers to what would need to be checked or even changed what are some other things to consider why this might be happening?

Err, well, when exactly does it "not cool down"? Like is it running hot or when you cut the engine does the temperature stay high for a really, really long time...What're we talking about here?

bryant

but it sounds like your fans are not coming on.

do you hear them after you cut the car off?

the fans cut on, even when i use the A/C trick to turn them on early t hey cut on, but it still does not go below 200. It usually stays between 180-190 but if the fans are not on it rises up to almost 260

air pockets?
not enough coolant?
bad water pump?
stuck thermostat?

So basically the fans are not switching on automatically?

i am hoping it is just a stuck thermostat as it was replaced just because 2 years ago, is there an easy way to fix a stuck thermostat? i got plenty of coolant. and shouldnt have any air pockets as the coolant hasn't been touched since last year

they do but at high temps, anytime i see it get to 200 i cut them on manually just out of habit and this time it didnt drop the temp at all

bryant

are you loosing coolant?

doesnt look like it, it almost sounds like the thermostat might have got stuck, i drove it to a sports complex to play a pick up game, it was fine then when i was done started it up and it looked like it didnt cool off and stayed at 200 with fans on and almost 240 with fans off

Have you got the stock tray which goes under your engine?

My car was missing mine when I bought it, and I would regularly see temps of 90+ (celcius) as a result.

And, not to nit-pick, but I thought Culpepper was spelled with two p's (or three a the case may be).. I know I've been gone for awhile (I'm originally from C'ville, can't wait to come home ) but didn't realize it's been *that* long

haha nah its one p. ya i have the undertray still. i drove it around yesterday in traffic just to put it thru some stress and it seemed to do fine...i think the fans for some reason just didnt cut on...but one other question, if your thermostat gets stuck, how do you go about fixing that problem without replacing it? do you have to take it out?

bryant

you guys make such a big deal out of the undertray.

i live in alabama, dont have a undertray and never see temp above 200.

unless im stupid and forget to turn the fans on.

well i never heard anything about the undertray really making a difference, i was just answering his question if i had one or not. car is about 95% original

bryant

just get one from Mazda its pretty cheap and would rule out that being the problem.

and yes you would have to take it out.

has this problem ever happend to anyone else? when i say problem i mean getting really hot one day and the next day being fine?

There are some different factors there... For people who have uprighted their radiator from FMIC installs, the undertray really doesn't do much. With the radiator in the slanted position, air can and will just go under the car without the undertray.

Also, if you do have the undertray there for the stock radiator position, you'll use your fans less as your radiator will be more effective with the incoming air being forced into the radiator (rather than just exiting under the car). So, will cooling work without the undertray? Absolutely. Will it work well? That depends on the setup.

the radiator is slanted, its a koyo and the undertray is there

Pull the thermostat and test it. It may be on it's way out. If you don't know when the last time it was changed out, now wouldn't be a bad time to do it. A new OEM thermostat is never a bad thing.

reddevil4896

iTrader: (1)

it was replaced like two years ago, think its time? i think if it does it again im definetly pulling it

bryant

i would not let it go higher than 230 or you could cause damage to your engine.
