overheating 1987 turbo II
alright...
a buddy of mine recently came across a good deal on a 1987 turbo II rx7. ($1500) and he went ahead and picked it up
the car is in fairly decent condition, has about 110k on it and had been sitting for about 4 years.
upon discovery, we hooked up a new battery and to our suprise it fired right up after about 10 seconds of cranking... blew a nice cloud of smoke out until it warmed up, and hasn't let out a puff since.
he got it trailered home (no tags) and parked it... when he finally got tags for it he drove it a bit and that's when the problems started. When it is driven (regardless of how) the Temp gauge gets hotter and hotter and hotter... until you get scared and go ahead and shut it down and let it cool off. (its never buried the gauge)
we replaced the thermostat, coolant level sensor, and coolant temp sensor and flushed the **** out of it several times and filled it back up with water, drove it about 40~ miles and it popped its cork once we got into traffic in town... the engine driven fan never came on and niether did the electric one.
sooo... i rigged the e-fan to run constantly when the car's on... and to no avail
the clutch fan runs for about 10 seconds when you start the car and you never hear it again after that.... we ripped out all the A/C **** to hopefully improve airflow and that helped some, but not enough. it has the stock 13lb radiator cap on it and it gets warm and hits the overflow tank blowing steam...
the car runs like a dream other than a slightly rough idle... turbo makes good boost (6-8lbs) and the car has zero exhaust other than the pre-cat.
sooo... i'm hoping i can get some help here... been going in circles on another forum to no avail... thanks in advance!!!

[quote name='jefraney' date='Aug 20 2005, 01:42 AM']Very interesting.
If there is no oil in the water or water in the oil and no steam coming out of the exhaust, it would have to be the water pump or a clogged radiator.

correct, no oil in the water.. and no steam from exhaust. sunday is the day of ripping the water pump off to check it out.... rad has been flushed umpteen times... idk we're at our wits end with this damn car lol
