V6 Ecotec Temperature

[WyldOne]

Hey all,

Had a few issues with my VT Commodore, V6 Ecotec engine overheating.

Just out of curiosity, I would like to know where does everyone's V6 Ecotec temperature gauge sit at?

[acarmody]

Half-way or if you read the digital temp on your dash, than ~91 degrees, what it should run at.

diff engine but so far i've seen 90-107c or so... 90c is cruising speed in nov, when it was cold

107 is in the middle of a heatwave with the air on

Mine sits always on half way, no idea why it does though. Short trips or long trips always gets to half way then sits there, I would prefer it to be cooler but I think its probably because its not exactly made for Australian conditions like they used to be. Aussie cars used to be made to always run cool but these things warm them self up pretty quick.
My VN always sits under 1/4 and if it gets to half then I think there would be problems although its never got that high.

[MikeCuzzy]

Most sit just below half way at the hottest, as does mine. It's between 1/3 and 1/2 if that makes sense.

By overheating do you mean you can hear the audible chime coming from the dash and the "HOT" word coming up in the cluster display? If it only happens shortly after cold start up (1st 10mins) it's most likely a sticky thermostat taking too long to open or if it's a longer intermittent overheating, intake minifold gaskets, heater tap or radiator could be the issue. All common well known issues to mechanics. Hopefully nothing major

Good question, or is it a more, "that's a fascinating smell" overheating.

An engine runs at it's most efficient when hot, running temp is anywhere between 80-100 deg C, entirely normal. Gauges can vary anywhere from 1/3 to over 1/2. 107 is OK on a hot day with the aircon on.

HAD MY VT FOR 14YRS (1ST OF THE 1997 VT,S TO COME OUT) its never ever gone past half even on 45C DAY

My temp needle always sits half way in between the 1/4 and the 1/2 way marks. Even on stinking hot days with air con on. The only time it has gone over was once when I tried to make a dash home after the top hose sprung a leak, (big mistake)

[Hangman]

My VS sits on 1/4 when cruising, halfway give or take in traffic.

My VP runs cold as according to the temp gauge. Will get to half way and kick the fan in sitting in traffic, but on the freeway it sits just above C.
I think the thermostat might be stuck open...

[Boltonator_VT]

Mine used to be quite high, but after fixing the radiator, it now sits a little bit below a half. Sometimes on hot days where I go from 100kph to a crawl in traffic, it can start to rise but my fans kick in at 1/2 and it never goes above this.

[IMCRZY]

Thermostat opens at 91c (asuming it has a standard thermostat) & fans come on at 104c so in saying that it should never go higher or lower than that, every needle type gauge will be a little different from car to car so thats nothing to really go by

[edals]

Mine ALways Sits here on the Gauge, Never moves, When In diagnostic mode only seen it go to about 104° then the fans kick in and comes back down, Most Times always at 91°

[showbags]

if your concerned it's running too hot, tridon make a 81 degree thermostat. the part number is tt203-180. v6's standard thermostat opens at 95 degrees not 91.

[WyldOne]

Well my cooling has got a new lower degree thermostat (81c), new water pump, flushed, pressure tested and new coolant over the period I have had the car. It now runs at around 80-95degrees so all is good! Thanks guys!
