Engine Cooling Fan not working on 3SGE motor Options

[Racer_J]

Hi guys,

Does anyone know how to fix a non-functional engine cooling fan on a 3SGE motor? Or even what could be causing it not to come on when the engine gets hot? Sick of using the interior heating to cool the engine down when in traffic!


Cheers

Well... I've had a look at my engine cooling fan(s) and still can't get them working. I ran a direct feed from the battery to each of the fans and they both switched on. But somewhere the system has broken down cos they still don't automatically come on when the engine is hot. I'm wondering if its a dodgy relay or even the temp sensor in the bottom of my radiator? I've checked the electrical connections and they seem fine.

Has anybody had a similar problem or could shed some light on this for me?

Thanks

Most of the people on CCUK who have had this problem have found it to be the temp sensor - perhaps do a search on there as I would imagine there's a simple way of testing it

That's what I'm thinking mate. I've had the connector off the sensor last weekend and the contacts are good, so it must be the sensor itself.

One of the guys at my local Toyota dealer said there's 2 sensors! One in the rad and the other in the thermostat housing. I changed my thermostat last year (as I believed it could have been that causing the problem) and don't recall seeing any sensor in the housing. I'll check CCUK then might just replace the sensor in the rad and have done with it!

Thanks for the advice.
