engine overheating?
well turns out i got the engine overheating light when i was on the 405 freeway going home from a field trip. i MIGHT have been going 80-85 constant. but anyway it flashed on so i put it in neutral and cruised off the carpool lane and it turned off immediately. i did use search but most people said it was probably coolant level, etc.
i'm an autotragic 2007. idk if this helps but im running hks hipower and ms CAI. no cooling mods done. and it wasn't even hot outside. maybe 85? anyway.. my brother said i shouldn't check my coolant level seeing as though it is pressurized. plus it felt really hot haha. i don't do much work on my car, but it would be nice to find out what the hell the problem is. |
yeah check the coolant level, and check your oil level, more highway more oil eaton. they are probably both low. where was your needle on your coolent gauge?

There's a overheating light?
|
It's the coolant level light...the most likely thing is a dodgy sensor that is a well known problem.
Either check the level lots and live with it...or buy a new coolant reservoir with a new sensor....I think Mazmart has a good price on them new |

i was hoping it wasn't a bad sensor. covered under warranty?
If it is still under Bumper to Bumper warranty and it is the sensor...it will be covered I'd check the coolant level first though ;) |
coolant was a bit low. so i got some coolant fluid and I'm waiting for the car too cool down. just wondering, but can i mix different engine oils? like as a top off
|
Yep...oil is oil really :)
(As long as it's good oil and it meets the OEM Specs ;) ) Added as a disclaimer :lol: |
haha thanks for the quick reply. thought so.

same problem
I am having the same problem with my 8 and all the oil and coolant levels are fine. it only starts to overheat when the a/c is on on a 100 plus degree day. What might my problem be?

thanks for the input guys. Ill try to see if anything is blocking coolant by flushing the radiator and adding purple ice to the radiator to see if itll be a cheap fix before i buy another radiator though that sounds like a good idea to do before the summer is over. Thanks again.

Make sure your coolant lines aren't "air bound." They occasionally have to be bled of air just as do your hydraulic lines. Of course this is much easier than hydraulic bleeding.

I've put in new thermostat and am still getting bubbling. How does one go about bleeding the air out of the cooling system?

COOLANT SYSTEM AIR BLEEDING Applicable to all RX-8 Model Years After performing repairs or modifications of the coolant system, the system must be purged of air. The following procedure will allow any trapped air to escape: 1. Elevate the front end of the vehicle. *A steep angle will allow air trapped in system to escape easily. 2. Temporarily remove the upper (vertical) throttle body coolant hose. 3. Fill coolant system with proper mix ratio of coolant/water per workshop manual. 4. Start engine and carefully monitor coolant level, topping off as necessary. 5. When coolant begins to flow from throttle body hose, air is bled from system. 6. Carefully attach coolant hose back to throttle body pipe. *Caution, coolant will be extremely hot! 7. Verify proper coolant level. 8. Check system for leaks. 9. Verify repair. |
For the folks with cooling issues on hot days..
Check out the cooling related DIYs in the Congrats thread. These are all really cheap things that made a huge difference for me. As for the low coolant light, I just unplugged mine. |

If anyone is intrested in a solution i'll write a small DIY for it. Greetings Thomas |
