1996 VS Taking 10 minutes to warm up

could check your computer for error codes (mite display coolant temp sensor problem or sumin)

howto check and also list of error codes http://forums.justcommodores.com.au/showpost.php?p=265242&postcount=3

hope this helps

 

is it taking 10mins to warming up while at idle?...or 10mins of driving to warm up?
because being an efi engine it doesnt need to sit and warm up, the best thing to do is to drive it as soon as the revs even out when you've started it up (usually takes only a few seconds)...

 

Your thermostat could be seized open.

 

is it blowing black smoke out the exhuast at all?, and what oil u using? not to thick is it?

 

Your car will not overheat with the thermostat stuck open. It will only take longer to warm up.

 

The easiest way is to remove the thermostat. This is under the housing that your top radiator hose goes to. When you remove it you will see straight away if it is stuck open. Should only take you about 10 min to remove, inspect & replace if necessary.

 

Slow Warmup = thermostat.

As already advised, slow warmup is usually associated with a stuck/sticky thermostat. It can stick anywhere from fully open to somewhere between there and closed. Usually it sticks part open.

If stuck fully open, the car will run very cool on the open road, especially in cooler weather.

I would investigate the termostat first, before anything else.

The fact that weather is colling down could be ab issue, but could not explain taking ten minutes to warm up.

 

Now that this has been brought up I have actually realised I get exactly the same thing on my 96 vs! Heater takes a good 10 mins to warm up, and i don't know if this has anything to do with it but i'm getting fairly piss poor economy lately as well? Could a thermostat effect that? (I've had o2 sensors replaced, throttle body and iac valve cleaned, complete fuel system checked for leaks but still manage to only get 350kms to a normal exec tank).

Cheers all,

Yes thermostats can be very critical for a cars fuel economy, especially a fuel injected one. In fact it can play havoc with the fuel injection duration thereby using excessive fuel and greater emissions. The heater will take longer to heat up if stuck open and by the sounds of things, that is the problem. If a customer came in with this scenario I would go straight to the thermostat assembly and replace it. If it needs doing usually a coolant change is also required as it may not have been changed in a long time! Never pull one out of a fuel injected vehicle and leave it out as a car not heating up correctly can be just as bad as one overheating!!!

 

i've got a s1 exec and i thought that geting ~400km/tank was normal because of its smaller fuel tank?

though admitably yes mine takes a good 5mins or so to get a hint of warm on it.

will have to look at that on a spare day.

 

Don't forget to check the vacuum operated heater hot water on/off valve - they can stick partially closed and only allow minimal flow.

 

as stated in the owners's manual, VR/VS dont need to be warmed up

if you are picky, rev it until it evens out then drive

 

hmm interesting
mine takes a bit of time to warm up aswell

 

I would suggest that what you are experiencing is pretty normal. In the colder weather, say 10 degrees and below, I can be driving for 10 minutes or longer, and the temp gauge has only just moved off the Cold position. My parents VS is the same, they just take a LONG time to warm up, but you can still get plenty of heat in this time, its just that the gauge takes ages to register.

I have climate control in my car, and no heat is available till the engine coolant gets to 45 deg C, so I am without any heat for about 3 minutes or so, first thing in the morning, and then it gradually increases the heat into the cabin.

As others have suggested, have a look at the thermostat, for the sake of $12 I replace mine every time I flush the cooling system, cheap insurance in my books.

 

yer my climate is the same

pity the thermostat on the super6 is a nightmare to get to!...otherwise id do it more often

 

How can you check if the thermo is stuck open?

Would this cause rough idol also?

 

Even though a manual says that a car shouldnt need to be warmed up, doesnt acually meen that its true. All cars should be warmed up before being driven so that all parts can come up to operating temperture and that the oil can come up to its required viscosity. My 95 VS never reaches the cold part of my guage, as its always below and i feel that it hurts my economy greatly along with engine life. im getting half as many miles out of it then i did out of my VN which never seemed to have any problems warming to about 1/4. I will investigate this firther.
