fan problems

[ctr kid]

i own a bb prelude 93 model with jdm h22 5speed conversion!

cold start in the morning or anyother time! engine starts as soon as u turn engine off, the radiator fan starts at "acc" position on the barrel! really strange. the only way 2 turn it off is pull out fuse , relay or batt terminal! even if u dont start engine once u ture the key and then ture it back 2 off it starts!

changed relay but still the same... thats it im selling it!!!!

any ideas???

accords and preludes have a circuit in them to run the radiator fan when the engine is off to cool the engine bay, its only ment to run when the enginebay is warm or hot

:thumbsup: :thumbsup:

but if the fan still run when the car hasn't been started than there is a problem but if you start the car and let it run for a while and than turn it off the fan still runs to cool down the motor and stuff

3rd gen prelude's do, but do 4th gen prelude's? Surely if it had a engine conversion, the controller for this may have been replaced.

yeah man if its got JDM in it it cuold have anything,

but your saying the fan is on all the time

could be a problem with the relay

does it have a thermostat or something to decide if its hot enough? this might be messed up???

ill check today! i hope its as simple as changing the thermostat!

i find that when i go for long drives, that when i turn the car off then the fan starts...
when i go on short drives then the fan doesn't start....

is taht what everyone is talking about?
