R33 Gtst Extrem Over Heating!

[FOURDOORR33]

HI ALL,,,

I have a r33 with RB25, Power Fc with hand controller,

Up untill yesterdy all was fine, not had a prob before with it.. water temp would sit 78 - 80 once fully warned up after (about 5 minutes) and might creep up to 83 after few hours driving,Fine right? been like that for years

Right,

My cars been sitting in the pannelbeaters the last couple months, (front bumper damage and minor side pannel damage) the radiator didnt get touched atall in accident baring in mind, but they had to remove the rad to do work, when i went to the place yesterday car was running, they said it had been running a couple of minutes and i looked at Fc hand controller and Water said 60.... i then revesed straight out of the unit (20ft) got outta car. talked for honestly no more than two minutes, Got back in car and hand controller was reading 114c!! pannelbeater says nah that cant be right because the stock temp gauge is only reading just above halfway mark?

Please all! Am gratefull of all advice!!

CHEERS AGAIN

Let it cool Nd check the coolant level. If its ok leave the cap off open the air bleeder screw on the inlet manifold till coolant comes out then refit the bleeder screw and start the car, let it idle till it warms up with cap off and heater on.

This should remove any air that is still trapped in the cooling system.

If it still overheats get a new thermostat

Try a new radiater cap.

in my experience, the stock temp gauge reaches half-way around 60-65C and will stay there till around 110C before rising - so it could be easily right.

+1 on bleeding the coolant system too.

I had a similar problem, my 33 was getting up to 100 odd, changed the spark plugs fixed the problem. dont know how but my car is fine now.

Flush the radiator. After i did my car, temps dropped 5 - 10 Deg C. Sounds like you have a bigger problem though to reach 114.

You may have air in the sysyem, When the car is cool remove the radiator cap and start the car, let the car idle for a while(might take 5-10 minites), giving it a few revs here and there, watch your temp gauge, and add coolant as needed, also ensure you have some coolant in the overflow for when the car cools down so it doesnt suck air back in.

Might fix it.

Thanks guys, it was just an airlock! cars back to normal running temps! cheers for all comments!!

Basically from my experience the stock temperature gauge should always be reading just under 1/2 way for a normal operating engine at normal temperature.

If it gets to 1/2 mark then thats enough to throw a caution, anything over 1/2 means there are potential over heating issues with the engine.

I had my gauge read just over 1/2 way & when I pulled over the coolant was boiling in the reserver tank, even though according to the stock gauge it's no where near the H mark, had it checked & it turned out to be a worn Rad cap & thermostat.

Thought so. Glad u got it fixed. Damn panel beaters thinking they are mechanics
