Q: Thermo fan or not thermo fan?

[HK1837]

ok its a fixed fan and it has no shroud..that will do it.

Greg, look closer. It has a HQ-HZ viscous fan. As far as I know all WB V8 had the square bladed viscous fan, which is the same right up till the end of VS in 2000.

you got good eyes byron...ok maz you only need a shroud then...

okkies.... do you have one you want to sell me??

I reckon when you get the shroud you should play around with different temp thermostats as they make a big difference as to where the gauge sits. I run a 4 row in my WB with factory air and a 4.2. It runs cool and really a 3 row would be big enough.

I'm not sure how good a WB V8 with V8 shroud and HQ-HZ viscous fan will cool though. Worth trying. But if not OK you should be able to use the same viscous centre and just put later (square edge) blades on it.

my tow vehicle, WB stato has the viscous fan and shroud and twin thermos that cut in at about 100 deg.

i use a 92 deg thermostat. the thermo hardly ever cuts in... and sits on 92-95 deg almost all of the time.

Factory air should have a thermo fan fitted as a factory item as well. It bolts to the rad support in front of the radiator on WB. So they run two fans. I don't think I have it on my WB. Never done enough traffic driving to need it.

That is right. I think the extra thermo was introduced in HX with ADR27A engines. My HJ Prem doesn't have one.

correct byron..single thermo fan..maz your shroud is in transit..
