Beastmode panda Posted November 10, 2013 Share Posted November 10, 2013 Did the engine swap, plugged the fan back up and when the ignition was on the fan went on straight away? :S. Engine hadn't even been run for 2 days so was dead cold. Now whenever the ignition is on the fan is on too? Any ideas guys? All I did was plug the 1 connector back in as normal.

TrisK Posted November 10, 2013 Share Posted November 10, 2013 Wrong connector maybe. Or you might need to bridge the connections. You do on a gt but not a glanza. But :/ Quote Link to post Share on other sites

But :/ Can't have the wrong connector man, only 1 plug on the whole car goes into the fan one lol! Same loom, same fan, same connector.. Just now it's on constantly :s.

morgey Posted November 10, 2013 Share Posted November 10, 2013 (edited) Be an old style sensor, you need a newer one. old style they work the opposite way around. off until a connection is made (gets hot makes a circuit) break in wire you have no fan.New style is off until connection is lost (gets hot breaks the circuit) its a fail safe as if the wire breaks it cuts in and you won't risk over heating.If you car could get up to temp I bet the fan would turn off ;) Edited November 10, 2013 by morgey Quote Link to post Share on other sites

Seriously? Do I need to take a sensor off that's plugged in then? Quote Link to post Share on other sites
morgey Posted November 10, 2013 Share Posted November 10, 2013 You swapped engines right?The water temp sensor that controls the fan needs swapping from your old engine. Quote Link to post Share on other sites

morgey Posted November 10, 2013 Share Posted November 10, 2013 Well that would be my guess. Quote Link to post Share on other sites
Beastmode panda Posted November 10, 2013 Author Share Posted November 10, 2013 Well that would be my guess. Might just get it wired to a switch lol. Quote Link to post Share on other sites
morgey Posted November 10, 2013 Share Posted November 10, 2013 Unplug the sensor and see if it stops.then run a wire from the connector to an earth. See if it stops or starts1)If it stays running when unplugged but stops when earthed then your sensor is open when cold but needs to be closed.2) if it stops when disconnected then your sensor is closed when cold but needs to be open.

I have this same issue. On my mk3 gt turbo 1994. The fan is always on constantly. Mines is 1) stays running when disconnected and when earthed it stops. is anyone able to confirm if it means I need the old type fan switch sensor or new type by this please?

akyakapotter Posted March 21 Share Posted March 21 Has the ac been removed ? If so you need to bridge one of the connectors by the battery. Will stop the fan coming on straight away. Quote Link to post Share on other sites

Will stop the fan coming on straight away. Managed to sort it now put an older type switch in and it worked the fan is now coming on at around 92 degrees is that correct and good for a 5E running 280bhp or would it be better to invest in a low temp thermostat?

Nilz90 Posted March 27 Share Posted March 27 It stopped working the next day anyone know what can be causing it to not function again? I have voltage coming to the fan switch Quote Link to post Share on other sites
