vr 5l temp doin my head in

[Matty o]

hey all been a while since ive been on but now i have a question about my 5l.
wen i bought it it had a v6 cluster in it n it ran about the line above a quater
on the guage then would creep up to bout half then found out the clutch fan has
packed it in. so any way we locked the clutch up so its direct driven to keep it
cool till i get one next week and put the v8 cluster back in just coz its ment to
be there. any now with the v8 cluster back in it sits on half or just over
and doesnt move even on the highway at speed so we then replace the thermostat n
no different. could this be the cluster playing up or the fan issue/
theres no leaks any where n also the tacho sits at 200rpm
at idle which makes me think the cluster. any help would be appreciated
sorry but the story but im tryin to write this on an iphone lol
thanks again...

200rpm at idle??? it should be sitting around 750-1000rpm at idle probs the cluster

[Matty o]

yea i knew it was low but just with the symptoms i thought it could be

[Matty o]

will the v6 do the same job or are they differently calibrated

[Matty o]

anyone????

[BottleFedVS]

the main diffrerence would be the V8 tach. every thing else should be the same as the V6.
I've got a V6 cluster in my VS Calais atm. I'm needing to change the tach or the whole cluster depends whats available here in wa

i might have a v8 tach here sumwhere

i cant work out y im gettin two different readings between the 2 clusters

[VrWagz1]

By the sounds of it, you have 2 shagged/incorrect clusters. I would shout yourself a new one off ebay. They are fairly cheap. I have played with clusters before. I have 2 half ones here and a vn/p one from the l3 conversion i did. They are finiky things.

[Matty o]

yea i mite have to. wot is the sensor underneath the throttle
body that has the single green wire coz i found it not hooked up?????

[VrWagz1]

lol, thats the dash temp sensor. maybe just the problem
The multiwire one on the manifold is for the ecu

[Matty o]

would the guage still work even if it wasnt hooked up

[VrWagz1]

shouldnt no. Its just a heat variable resistor that earths out the gauge slowly as the motor gets hot, giving you the needle rise. If its totally open cct, the needle should never get off the ground. If it was dead short then the gauge should be off scale.

[Matty o]

the guage dont move wen it gets to a certain temp not even
at speed on the highwayy would this still indicate the cluster issue

[VrWagz1]

Thats a strage scenario you have really. Cause it shouldnt operate at all if that wire is dosconnected. Maybe that wire you had was not the temp sensor wire. Have search on here or google for some picrures of where the sensors are located. If its the temp dash gauge sender unit, it will be on the base of the inlet manifold(under the throttlebody) next to the ecu temp sensor (so theres 2 sensors there beside each other).
If the cluster is still working(albeit badly) then theres definatly a wiring or cluster issue there.

[Matty o]

ok yea im thinking cluster hopefully
