Hey guys so if you dont know i just bought an 88 rx7 it didn't run for 4 years. Well i got it running tonight, now my problem is when we fired it up it smoked at first (normal) then it went away. The engine got really hot in a matter of like 2 mins. The temp gauge was reading normal. I checked the coolant at the radiator before i started and it looked normal and was full, I didn't check the upper one though. Do you think that it might have air in the line? If so what do I do? So if any of you have an idea i need this thing on the road by this coming monday so help me out if you can.

 

If it gets got just idling you need a new E-fan. If its always hot, you need a new fuel pump or thermostat (is plugged).

 

wait

so the temp gauge was reading normal? as in, not overheating?

 

yeah thats a confusing one, it was hot but the guage was normal? Rotary engines tend to put off alot more heat than a regular piston engine. So maybe that's why it "seemed" really hot. A good idea is to install an aftermarket water temp. gauge that way their's no mistaking what's going on

is the car getting hot or not???

 

ye it is it smells very hot feels very hot and started steaming or smoking i vouldn't tell it was dark out side

 

do a full 60k tune up if its been sitting for 4 years.

 

+1 on the 60k tuneup. That should take care of some of the stuff that could be bad. Just replace all of the small stuff and then see what happens. If its still running hot at idle its either in the cooling system or for some reason your running super lean. Which could be stopped up fuel filter causing issues, or a bad pump or pump with low voltage. Could be any number of things
