Ok... I am confused like nothing else... I had an overheat and turns out my t-stat died. I replaced it with a Mazda t-stat straight from the dealership with new gasket. Everything was cool... now temp is up again. I need to make sure of a couple of things...
1. Is 5w30 ok for cali right now with temps being between 80 and 90 degrees... 2. What coolant mix is recommended for a 13b 2+2??? 3. If these are ok... how do I preform a presure test??? Help!!! I miss my car!!! https://www.nopistons.com/forums/pub..._DIR#>/wtf.gif |

Is it actually boiling over when you show a high temp? To perform a pressure check you need a coolant system pressure checker, goes on the radiator, you pump it up see if the guage leaks down. |
Oh yeah... I was on the side of the road with my car smoking white smoke. It was indefinitely the t-stat. And right now I have 100% coolant in my radiator. Am I wrong for not having mix? And is 5w30 ok for an engine with almost 200k miles?

No it should be fine with 100% bad news is rotary's really dislike overheating, you may have fucked something up.
|
is your fan working properly? are you sure that you bled all the air out of the system when u flushed it?
|
100% coolant is good??? I thought it was supposed to be 50/50, or more water than coolant for hotter seasons/climates.
|
Well... yeah... this is the only time I have ever heard that you SHOULD put 100% coolant. And BTW... is the temp gauge being at 1/2 durring hot temps???
|
coolant should be at least 50/50 if not 70water and 30 coolant in the summer, water cools better than antifreeze.
5-30 is a little light, but should be ok |
I didn't say it was GOOD, I just said it should be fine. I've never heard a 100% anti freeze mix overheating a car, but then I've never ran anything over 50/50
EDIT: Hmm well I guess I was wrong, it could I guess overheat your engine, water absorbs almost 2 times the amount of heat as glycol, so i'd start there, although I don't know that it matters overheating a 200k plus rotary can't end in happiness |
ok here is another question... how about what TYPE of coolant... should I just stick with Prestone Green??? Or should I switch to something else?!? I was told by a guy at napa that I was recommended to use a coolant with dexcool. So I am confused...
