Wheres the thermostat on a vectra V6

[brian chim]

Got to do the thermostat on my 1998 2.5 V6 vectra on saturday. Can anyone tell me where is it positioned so can go straight to it to save me a bit of time.

Cheers Brian

its under the inlet manifold in between the heads

[brian chim]

will i need to strip anything out like the inlet manifold? How long do you think it would take?

Cheers Brian

[steve vxr]

yes the inlet manifold will have to be removed and best to get new seals, last time i did 1 it took about an hour

Right hand side looking at the engine bay?

How much and would it be worth doing the water pump at the same time?

[steve vxr]

its on the left between the heads, i wouldnt change the waterpump unless it needs it

You will need to split the thermostate housing from the front pipe. Remove the twisted top radiator hose, remove the bolt that hold the dipstick tube. Uses a set of pipe pliers to grasp the tube where you have removed the hose from. Rock it back and forth while levering the tong out towards the rad. It will be very tight.

If your confused it will become clear when your down to the thermo housing.
