and i'm getting worried, my radiator fan wont come on, i want to change the temp switches on it but i dont know exactly what they are so does anyone know the part number and where to get them, its a 1.6 n/a diesel it has two switches on the rad and i want to change them both (its not the fan as it works when wires going to switch are shorted)
thanks for any help

In all the time I've had the van I have only ever heard the fan come on once and that was when the engine had been running for a long long time in a stationary van.

I have some kind of extra fan fitted for hot country use that runs off a switch under the dash. I have seen this discussed on US Vanagon sites also. I've never used it in anger but I suppose I could if the temp was climbing.

1.7d na KY engine.

cheers i'll go down to gsf,
the reason i'm worried is my temp guage went up to 3/4 of the way on friday in that hot weather and no sign of any fan movement so i shat myself, luckily the traffic started moving and she didnt blow but think i'd better change the little buggers.

just remember the fan takes its temp from the rad switch, the gauge from the engine and they are 17l apart........

never come on till 3/4 or above and any ive seen...........

ah, so is there anyway of testing these switches apart from getting the engine really really really warm?
(and at what point on the temp guage do you start getting nervous)

I get nervous when its in the red.

If you can remove the switch, then rig a rudementry circuit with the switch in a pool of water that can be heated maybe.

has the fan been checked to see if it runs out of the thermo loop
