on the slam panel passenger side, to the right of the washer bottle filler spout you will see the mounting bracket for the fan control relays, follow the looms from that, one of them will go down to the resistors which are mounted below the contoler only way of testing them is check for continuity across them and seein if the rateing is printed on the caseings and go from there

hi all i have a 97 2.8v6 ghia x

when iam in traffic the temp gauge goes right up just into the red then both fans cut in a pulls the temp back down Ive had this checked out in a garage and he said that the water temp (tested it with a temp laser gun) was not getting as hot as what the gauge was saying weather you can test the water temp like this i don't know when you have two fans on the rad should one come in before the other to stop the gauge reaching the red and then if it goes into the red both fans cut in like a emergency to get the temp down if this is right what can be stopping the first fan cutting in a reasonable temp please help as wife is driving me mad thinking the car is going to blow up

got your reply out the resister 27 someone else said it could be on of the sensors on the thermostat there are 3. or could it be one of these relays on the slam panel at fault

please help me out

Hi,

On my mk2 2.8V6 there is a sensor on the battery side of the radiator (about half way down). This has two temperatures stamped on it (105/95C - or there abouts), this then leads to the fan controller (I think). It could be that the lower temp is not triggering the fans and they are only coming on at the higher temp - perhaps this could be tested by shorting out the various combinations from the sensor. I vaguely remember when I was checking mine I had it stuck in boiling water with no effect and only got the fans to kick in with with a hot air gun on it (It's a shame that I didn't repeat the test with the new sensor to see what happened!). Saying that my fans only come on together even now, but my temp dial never gets past half way.
