Got all the leaks fixed from the cooling system, new water pump, gaskets, hoses,and thermostat, new temp sensor as well. Now it's blowing coolant back into the reservoir and not sucking it back into the system, from there it blows it out of the pressure release hose on the other side of the reservoir. Any informative input would be greatly appreciated

 

Which model RX7? What is mileage and mods?

 

I don't see a new rad cap on that list.
also if the Hoses between the Rad and the overflow bottle are fubarred it will allow the coolant to go into the bottle but not return.,
You are looking for a bad hose most likely around the overflow cap and the little hose inside the bottle.,
The jug needs to have coolant in it to return it.If not it sucks air and you get air in the Cooling system and it can cause a number of symptoms.,like Coolant buzzer going off,coolant expelling because of a hot spot in the system( due to air).etc.

 

86 rx7 wanna say s3, put a new rad cap on it last night 16lbs. non turbo 135 thousand miles. Don't think there are any mods on it I've only had it for about 4 months. haven't had time to flush the system but it's on the list of things to do. there was a 13 lb cap on the radiator and im thinking that might of been the problem hopefully so thanks and let ya know if that takes care of it.

 

13 to 16 PSI shouldn't make a difference or cause what you saw.

Consider doing a coolant system pressure test.

 

Do I buy the equipment or would it be cheaper taking it to a shop to do that?
