I find a lot of info in this forum. Thought I would introduce myself. I have a 93 rx7 teal all original. I’ve gone through the whole car with new brakes pads and rotors, all new hoses, new original radiator, the higher capacity radiator It had when I bought it rubbed on the fan housing causing the cooling fans to quit working so went back to the original radiator & housing. Runs cool even at high temps.
I Installed another switch in the center console to activate the fans after shut off to cool under the hood. It’s wired wired to the existing CPU timer feature. When the switch is on it runs the fans 10 minutes after engine shut off to cool the engine compartment and keep the rubber hoses and components from excessive temps. I learned about this option in rx7 club when I was concerned the car would run hot after changing the radiator.
The car also had a turbo timer and boost control installed when I got it. I don’t know if the boost control actually works. I’ve had the car two years driving once a month. Passed smog back then and just got a DMV registration renewal requiring another smog.
The last time I checked the fluids I noticed 2 vacuumed hoses disconnected under the intake and plugged them in. But not sure if they are correct.
I looked at the vaccumm diagram under the hood but was hard to read and determine which hose was which.
It also has a gasket air leak in the intake manifold right above where all the Vacume hoses are. Also the cruise control will not stay activated. It sticks then releases, engage release intermittently, the cars slows down then cruise light goes off. Still working on that one. The car runs great other than a few rattles and knocking Sound in the rear undercarriage With any jolt. I’ll post when I figure these out.
