My eg's been slightly overheating this summer. I dont drive it to often but when i have temps rise up. The problem is, ive done alot in the past to prevent overheating issues. I recently rebuilt my head, got a new turbo and tune and now its overheating. I dont know its its just coincidence because its summer but take today for example it's 38 outside and the car temp rises upto 84 whilst driving and stays there for a 10-15minutes and then after that it will go upto 95 max and go up and down in the 90's. I've got a aftermarket Koyo radiator, Mugen thermostat (6 months old), anti freeze anti boil coolant, and Thermo fan ive set to power on accessory power so its always running, but the car still wants to go over 90 degree's in this summer heat. Winter the car never goes over 85 degree's unless i thrash it.
Engines done about 75,000 now (b16a2 japspec) and been rebuilt 3 times...currently only has less than 1000 on the engine since rebuild.
Question is the only other things i can think of is either my radiator sitting behind my mammoth front mount isnt allowing enough air through or my water pump is having issues or where my air intake sits its getting alot of heat from the turbo manifold and sucking that hot air into the car air intake temps can get upto 60 degree's.
1 weird thing is the temp only rizes up when im on the freeway over 100. Stop start driving on 60-80km/h roads the temp only gets upto 89 max but soon as i hit the freeway and sit on 100+ the temps sore over into the 90's and slowly creep up to 95. I would have thought, more air flow = cooler but it seems that because the car is under mild load constantly it doesnt like it, which got me thinking it was water pump or air intake temps instead of an issue with the flow to the radiator.
Any idea's?
