GTSBoy Posted February 27, 2014 Share Posted February 27, 2014 Ah. I was under the impression the remap was to suit the turbo already somehow, not what I guess was the previous turbo. Makes sense now. Link to comment https://www.sau.com.au/forums/topic/438910-radiator-suggestions/page/3/#findComment-7212681 Share on other sites More sharing options...
iruvyouskyrine Posted March 2, 2014 Author Share Posted March 2, 2014 G E T R I D O F T H E G K T E C H F A N I had heat issues for the first time ever after replacing the fan from stock to GKTECH, changed them back last weekend and test at SMSP and temps are back to perfect! Drove the car on saturday when it was pissing down rain, maybe 12deg outsde crusing at 60km/h in 4th gear doing 2000 revs. Temps reached 120deg. > Put standard fan back on (not even a good quality one, i cut about 1/3 of each blade away so it didn't foul on intercooler piping) > New coolant > Bleed system > Has not gone over 80deg so far Seems like Matt may be correct.

C4a0s Posted March 3, 2014 Share Posted March 3, 2014 maybe the gktech fan is turning in the wrong direction or has the blades mixed up. so instead of pulling in air thru the radiator.. its pushing it.

Awesome! Its the only change on my car and its sorted! maybe the gktech fan is turning in the wrong direction or has the blades mixed up. so instead of pulling in air thru the radiator.. its pushing it. This was my first thought too, but all checked out OK, fan was just rubbish!

Dose Pipe Sutututu Posted March 3, 2014 Share Posted March 3, 2014 bottom line, it's just shit lol same thing on my mate's S15, OEM fan cools better.. the GK Tech one just makes loads of noise and that's it Link to comment https://www.sau.com.au/forums/topic/438910-radiator-suggestions/page/3/#findComment-7215746 Share on other sites More sharing options...

There is quite a few of us that have had issues... Post a pic of your setup for comparison? The blades on the OEM fan are way bigger and work so much better... They are closer to the radiator too!

No need for thermos etc... actually once the engine is warmed up, there isnt a need for a thermostat when u are on the track. in case it might impede the flow plus... if the thermostat jammed... u'd have a problem. happened to me before..

Ben C34 Posted March 3, 2014 Share Posted March 3, 2014 (edited) .. The fan cant spin backwards, unless the engine did! If the fan is on backwards it would move less air, but still the correct direction.

Dose Pipe Sutututu Posted March 3, 2014 Share Posted March 3, 2014 ^ unless the monkeys at GK tech have moulded the fan blades wrong so instead of a pull fan it has become a push fan LOL Link to comment https://www.sau.com.au/forums/topic/438910-radiator-suggestions/page/3/#findComment-7216161 Share on other sites More sharing options...

Heres a photo of my bay as you can see no special ducting or anything just std shroud with the koyo rad and lol half of whatevers left of the plastic undertray. Weird why some setups works some doesnt. OP what car do you have I was also at matsuri last weekend in the white 33 with bogged up rear quaters.

JordansR32 Posted March 5, 2014 Share Posted March 5, 2014 I have had the same troubles with over heating, after a good flogging of the car would get pretty hot, hotter than it usually has, investigated more and found a coolant leak, fixed that, tested again, same thing was happeing again, found another coolant leak, finally fixed the last coolant leak, took the car for a drive and it still is getting hot after like 5 minutes of skidding, the only thing I can out it down to is the standard fan, I had to chop about 2 inches off it to clear the cooler pipe, still had stock shroud and aftermarket radiator. Just brought some thermos gonna install them on the weekend and see how that goes with the temps, I'm hoping that this fixes the overheating issues!

iruvyouskyrine Posted March 5, 2014 Author Share Posted March 5, 2014 I was using the GKtech fan and having issues. Swapped to my chopped out standard fan (I had to cut mine just like you did) and it has fixed all my problems.

Just brought some thermos gonna install them on the weekend and see how that goes with the temps, I'm hoping that this fixes the overheating issues! I wouldnt blame the fan for that... I would start by going back to basics! Make sure all leaks are fixed and then start working on things like the radiator... Is it blocked, is it getting airflow etc... Waterpump... Is it flowing, is it worn etc... Headgasket... is it pressurizing the cooling system and causing your leaks bla bla bla I was using the GKtech fan and having issues. Swapped to my chopped out standard fan (I had to cut mine just like you did) and it has fixed all my problems.
