Thermo Fan Previously Disconnected?

[LUKE R34]

Hi All,

Merry Xmas to all

Been searching around and have yet to find any info on what im trying to achieve

i own a R34 GTT and the previous owner told me the thermo fan had been disconnected at some stage by the first australian owner after the car was imported (im the 3rd owner) , saying the car never got hot enough to need it , well maybe they were not as spirited in the seat as i am cause it got hot, so ive changed over to a bigger alloy radiator and taken out the original thermo which seems fine no movement in the unit and spins fine

ive asked the previous owner if he knew exactly what was done to disconnect it but he doesnt know?

the fuses are all in japanese so i got no idea there?

the thermo all seemed connected when i removed it everything seemed stock

there is another connection below which comes out from near the horn which i took a picture of but doesnt connect to thermo

all i want to do is find out what has been done to stop thermo kicking in and fix it

and either replace thermo or use original , would be nice to have it on a switch also,

seemed simple enough to me but i got no idea about wiring and electrical side of things and the fuses all being in jap is just great

so anyone got some suggestions or ideas on whats been done and how i can fix it?

also is there a thermo fuse?

an english translation for all the fuses?

how to test original thermo ?

Thanks All, and have a safe xmas and new years , lets go 2013!!

I don't know R34's well, but all Skylines have a thermofan infront of the aircon condensor (looks like a radiator). This will switch on automatically when either the aircon is on, or the coolant temperature reaches 95C+ (approx).

The thermo fan is an over temp fan. As long as the cooling system works fineit should never come on anyway.

@Moodles2 yeah thats the fan ive removed which no longer switches on but seems in fine working order

@mad82 the car shat two heater cores in a matter of months as soon as i flushed the system? which to me sez it was a build up of shit holding the first core together

but then doesnt explain why it did another apart from the coolant being too hot from the old radiator?

the thermo or over temp as you call it has never kicked in? at least ive never noticed it, and when the car gets hot it needs to be driven lightly to bring back down if you stop it and sit ,it will get hotter or stay the same ,ive replaed the radiator now with a massive 56mm alloy unit and bypassed the heater core and it seems fine ,took the car for a good drive down highway all was fine, sat it for 10mins running and did not get hot, but i still want a thermo for hot qld track days

will look at getting the original thermo tested and wired in on a switch, i test fitted a massive 16" thermo and while it did fit (only just) its just too big

if i have to replace it i will just go 10" for easy fit ,

so no one knows anything about the wiring?

at speed (such as on a track day) having the thermo there won't do much good. it may even restrict the airflow a little bit. plenty of race cars don't run fans at all as they just rely on the air at speed to keep things cool

funny you say that bro cause i was just looking into that, the engine/clutch fan seems to work a treat so with the big alloy number and the engine fan i think it should all be sweet

cheers for the feed back guys it all helps

have a safe new years
