VS Commodre Temp Problem ???

[steven2760]

Hi i am new to this site and am wanting some help with my VS Commodore.

I am having some problem with my VS getting quite hot. Even on a cold, raining day the temp is sitting at 1/2 way, and when i am stuck in traffic it gets up to 3/4 before the fan kicks in.

I am just wondering if this is normal for a VS ??

Is it possible to change anything so the fan turns on earlier ??

Thanks Steven.

pretty sure fan settings can be changed in the ECU but that would be more effort (and cash) than it's worth on an otherwise untouched tune.

First thing is to make sure the cooling system is up to scratch.
You may need to flush it and replace the thermostat and radiator cap (cap has nothing to do with temp but I always do both).
If it still runs hot, remove the radiator and have it tested for blockages (or do this as part of the flush).
If still to hot then maybe start looking at the electrics. The earth near the battery is a good place to start.

yes normal

3/4 is approx 110 deg c and the fans cut in, 1/2 is approx 100 dec c and 1/4 is approx 90 deg c
( i have checked these temps with tech 1 my self. i work at a dealership)
its just a missleading gauge

but as mentioned check the cooling system o be sure its up to scratch

The other alternative is to wire the cooling fan so as to manually switch it on....or turning the A/C on turns the fan on.
Otherwise it's completely normal and part of the design of the Ecotec engine system.

Someone on here the other day posted that they bought a temp sender for the temp gauge from holden.He said it was a different length,and when he fitted it the gauge went to 3/4 before the fan cut in,where as it was cutting in at half way before replacing the sender.He said he took it back,they ordered another one, a different one again,and the gauge reads normal again.Fan cutting in at half way on the gauge.
The people who's gauges sit at 3/4 normally might want to look into this.They might have a different sender fitted.

99% of the vs commodores i drive works like that, fans cut in at 3/4 etc, my vr with level 3 cluster cuts in at half way where as before with the level 2 dash cut in at 3/4, perficaly normal i wouldnt touch it unless its acculy boiling or you are loosing water, you will just be wasting your money, but its your car not mine

Interesting situation.

I don't think I've ever seen a VS with a gauge showing 3/4 before the fan cuts in that hasn't had some sort of cooling system issue.
To me a fan that cuts in a 3/4 is not normal and requires some investigation.

same with my v6 vs ute..the temp gauge will go up too 3/4 while idling ....i had since new, now 14 years later
since i fitted a 2 1/2 inch sports exhaust last november the gauge has not gone past half always stays around the 1/4 while idling even with the ac on during a stinking hot day

Yeah, that was me - But I will stress that I was recalling my experience, I don't know whether the longer one was faulty to begin with. The shorter replacement sender works, and thats all I need to know for now.

EDIT: I cross-checked the readings with EFILive at the time, so I knew that even though the gauge was at 1/2, the coolant temp was still at normal operating temp.

If the engine is not overheating then it don't matter whether the gauge reads 1/2 or 3/4 when the fan kicks in. The gauges and sensors are not precision items and only give an indication of what's going on. It's just like "normal" operating conditions.....what would that be?... in Darwin or Hobart, summer or winter.
My opinion, FWIW, is the same as others have stated above: keep the cooling system in top operating condition and watch the gauges for anything "out of the ordinary".

Can anyone help me? my driverside sun visor falls down when i go over any bumps or uneven road is there a way to tighten the shaft ,any ideas

My VS was doing this and I found the radiator was cracked around where the top hose goes on. Just a hairline crack but when it got hot it pissed water out. Get your cooling system pressure tested and serviced/flushed. :-)
