Vr problems

[Kovacic_VR95]

G'day guys, i know one thread at a time haha...

Q1. Ok with the vr i purchased for sum reason the thermostat aint working even after i turn the car and drive it around for 2hours now i guess thats a thermostat problem and all i have to do is replace it for around $50?

Q2. Also the tank was empty the other day i put $10 in and the dile in the fuel gauge came up half way i was like hang on ther was nuthing in it b4 now is this a fuel sensor problem or??

Q3. Another one, when im driving and come to a red light ill break now when i break and the rpm get low near 500rpm or under the car has a like eletrical sound like it has stopped but hasnt stalled weird, wat is it?

If you guys know anymore problems with vr commodores that are common throughout may you reply back with more as dont want to do thread after thread.

Cheers

Bit of work there for yourself.

1) ChRiDDa has made an excellent how to up on performing a full service on the cooling system here: How To Flush A V6 Cooling System

I would run through that. Includes replacement of the thermostat (not as expensive as you think).

2) In the fuel tank there is a float that goes to a variable resistor. As the fuel tank goes up and down, the float goes up and down which slides the variable resistor. The resistor sends the level to the instrument cluster. It is possible that this has been damaged. If someone has been rough removing the fuel pump for example, they may have bent the wire rods which will cause the variable resistor to give odd readings. I would fill the car up, watch it work its way down during your driving and see what you find. It could also be the instrument cluster, couple of different faults there that it could be. Give the top of the dash a hit next time it seems a little low and see what happens.

3) Can you describe the sound that youre hearing a little more. Revs should drop to about 700RPM. This is controlled by an IAC (Idle Air Control valve). You could try cleaning the throttle body out, which also includes this IAC valve. Instructions here: CleaningThrottle Body VR V6

You can also check for error codes as shown here Checking error codes VR/VS (Revised)

These are very easy to check and will sometimes give you a good starting point to fix a problem.
