Checking Radiator Fan and Thermostat

Post by Mick & Tracey »

Hi

Suspect my radiator fan is not cutting in went it should - what checks can I do?
Running AAZ, tends to run hot if left on idle for a long time after a run, but fan not kicking it (up to 3/4 on temp gauge - didn't want to risk going any further).

Have put a jumper wire across the fan connector block - fan runs on high speed when jumper across middle and one terminal, nothing when across middle and other terminal so I guess low speed is not kicking in for some reason.
So maybe two problems - low speed fan and stat.
Are there any checks for the stat?
How do I check/fix get low speed fan operation

Cheers
Mick
