Hi All,

Just would like to know what the disadvantages of mounting the thermo fan/s to the front of the radiator as opposed to the back like normal. I've got no room in behind my new radiator to fit a fan :D , so i was going to put it on the front.

So what are the disadvantages of doing this?

Thanks,

Joh

If you read the instructions that come with the fan, I'm pretty sure they will recommend mounting in front and pushing air through, rather than mounting behind and pulling air.

The main reason for mounting behind the radiator is that there is rarely any space in front, what with an A/C condensor and maybe a FMIC.

i was thinking if i got two 12 inch on the front it might restrict airflow thru the radiator itself.

thanks for the replies...

You really only need any sort of fan for when the car is stationary or moving slowly, which can result in a slight increase in coolant temperature. At general road speeds, the movement of the car creates sufficient airflow through the radiator to control the coolant temperature.

A single 14" or 16" fan should be sufficient for the job.

      R32 only blows hot air

      By Duncan · Posted

      Not really, but the heater box is pretty simple mechanically....if the door is one way the air bypasses the heater core and if it is the other way it goes through it for warm air.  If you are sure the actuator you moved manually is for the heater mix (there would also be one for output air direction) then I'd take the heater box out and see what is happening (you'll have to regass and re-coolant the systems afterwards) BTW pp724 onwards from the GTR workshop manual cover the system in good detail, it is probably worth checking. I think the IAT sensor might be a problem electrically for getting cold (if you got 24 error code not -24 it thinks the incoming air is -50c) and it covers how to test the sensor (although most likely it is either not plugged in or a wire is damaged)

      Use the GKTech subframe bush and bring your subframe 10mm closer to the chassis. You'll need to fix an exhaust hanger to suit. One of the best mods I've done.

      You'd really have to pull it apart further to know, it least you can be confident that the one heading to the back is not connected any more. There was once a ground on the shifter seal mount too, your head unit issue could be that simple

      Perfect, I'll get to it this winter then at the same time as I weld on my anti squat kit.

      R32 only blows hot air

      Alright so my 32 only has one temperature no matter what degree you set it to. I’ve tried disconnecting the servo motor arm and moving it either direction and got no change. I’ve fixed the leak in my AC and re charged it and with it on and clutch engaged it still blows hot even though the low pressure pipe going to the firewall is ice cold. Both heater core hoses are hot while running as well. Diagnostic code showed 24 for intake air temperature sensor. Anybody got any ideas?
