thanks

 

Hi, what's the most likely cause if the fan cuts in too late (as in over 3/4 on the temp guage) but comes on straight away with the AC turned on. The radiators' got new coolant, new water pump, bled etc.

The car runs at like 1/4 when driving but after you pull up for a bit it gets hotter and hotter until it's very hot before it starts too cool back down (ie. thermo fan kicks in).

I did the test thingo by removing the temp sensor wiring and starting it up, it correctly came on low speed at 6 secs and high speed at 12 secs or whatever the time was according to the gregory's... and all seems fine. VS V6 motor

 

Thanks Doc. Only thing is though, as I said it drives cool - and if I switch the AC on as I'm slowing down, and stop, it stays cool. If the AC isn't on it gets hot after I stop.... if i switch the AC on (fan comes on straight away) it pretty much instantly gets cooler again.

That's all that makes me think it's just cutting in too late, as when its forced on by the AC the temp gauge stays at about half.

That beign said it was hot today and went for a 20km drive in often stop start lights and it was still under half way and getting warmer still???? Shouldn't take that long should it????

 

Upgrade of VE SV6 to Three Window Cluster?

Hi Dr Bob,

I have upgraded my last two cars, a VSII and a VYII to a three window cluster.

I have now succumbed to the good pricing, and bought an SV6 manual. I would like to upgrade the cluster again, but am getting mixed messages from most sources.

I understand that the cluster is tied to the particular vehicle. It appears that it now requires more than a Tech2 calibration to install a new one, i.e. can only be done by a dealer.

Before I cough up the bucks to buy a new cluster, are you able to confirm whether the upgrade is feasible, and if so, what is involved?

I am aware that you were able to set up VY and VZ cluster for a price. Do you have similar capabilities with the VE?

Thanks & regards.
