i need help. i just got an 83 rx-7 for $50 and know it has a bad thermostat, and a problem with the idle. it won't idle on its own and has trouble with starting, it almost sounds like it is running on one rotor at first until i rev it up to 3000rpm. but that isn't why im posting. the reason im posting is because today when i started it to pull it into my garage to work on it i had radiator fluid shooting out of the exhaust. i almost drained 1/8 of the radiator fluid out of the radiator in almost a minute. if anyone can help with this or if anyone has an exploded view of the 12A engine i would appreciate the input

 

cracked housing...bad waterseal...bad news...... look for a motor or do a rebuild and look for the new parts you need 50bucks not a bad deal

 

Unless fluid is getting into the motor through the intake.

 

ah yes i for got some ppl still use stock intakes....freez plug will fix that leak if its the problem

 

If the coolant is coming out of the tailpipe, rebuild time.

 

+1
reccomend diag little further before replacing the engine

 

i have an 83 aswell and and it started pissing oil from one of the mid seals and it sort of forced me into buying a turboed 12a j-spec. what im saying is if you have some extra cash buy a motor if not start saving or buy another parts car, wich it sounds like you got stuck with anyhow. do you live in the new york city area, cuz if so i may have a motor you just need to drive here.
