Rx8 dumping coolant in my AEM dryflow
why is my rx8 dumping coolant in my aem 485r dryflow? i overfill it but not that much..i dont think that has anything to do with it..it only happens when i turn off the car..not all the time but 2 out of 5 times..my rx8 is an 06 with a rebuilt engine at 153k..right now im at 155k..this is not my daily car

It is likely boiling over and exiting the overflow hose and dripping down to your filter. You need to fix your coolant system, something is not working right. DO NOT OVERHEAT IT, even once. fix it.

I would check to see if your coolant is running low or drops within a couple of days ..... Have you ever replaced your radiator ? I have had mine since I bought the car new in 2004, I had to end up replacing it and a lot of the hoses due to deterioration. The plastic literally turned to dust on the top opening of the radiator causing the leak between the inlet and the hose; It would shoot coolant out at random times towards the inner front facia and the air box. (just something to consider as all our cars are getting older)
Best of luck !

You could end up throwing a lot of money at the car that might not be needed.... It could be just as simple as the L shape hose connecting the radiator and coolant reservoir together. Last summer I ended up having to replace everything
thought it was the tank: replaced it (fixed my low coolant light) and in the process found out that the radiator turned to dust.
Bought a new Radiator (BHR) and Racing Beat Hoses. Car was still leaking
Ended up realizing that the tiny hoses that looked fine and held water would not hold up under pressure and would sometimes leak into the inner facia and air box. Mazda says you should replace them every 5-8 years.

how much coolant does it have to be in the reservoir? i have to pour some every time i want to take the care for a spin because somehow after i let it cool down there is a little bit of coolant in the reservoir..do all rotary engines take so much coolant?

thats what i think it is..i see dried coolant on some parts of the engine..do u think for someone who does not know about rotary engines can do a pressure test on my rx8

Check the little plastic nipple on the radiator, it is near the overflow bottle a bit to the right of it and down. If needed I can upload a photo for you. My car was doing the exact same thing when my nipple had cracked off. It is a very common issue with our stock radiators sadly.

Here yea go man, great DIY to fix the issue if it is actually the problem, or you could always just convince your self to go out and buy a performance radiator, especially now that its summer! Great investment IMO.
