I would also agree that you should get a test tool, I use a Nanocom personally. (You will likely want one for other diagnostics before long, and it could show issues you are not aware of)

I would buy the new thermostat through British Offroad if you are unsure of which you need, they only sell one - and it is the correct one. (Lower temp)

When I had my head gaskets done there 2 years ago they didnt recommend that I fit a colder thermostat - they put in a new stocker, so I dont know if they have changed their view since then.

"heat affected bonnet"
:lol2:

try The Great Australian Sun affected bonnet!

The dont sell it as "colder", its just what they have and it happens to be the cooler option.
My opinion is that in Aussie conditions you want the coolest available. My car now runs at 88-90c in pretty much all conditions, under bonnet heat is greatly reduced and the thermo fan no longer runs in general use. (only extended idle)

We are both wrong, i knew those figures by heart for Td5 and was carried away so forgot we are speaking about a V8:(, it seems that on the V8 there's exactly 10*C difference, i apologise...see ttachments

the way the gauge works is the same for both though so you can drive the V8 at 99C without knowing it or if the electric fan is seized at 119C before the gauge goes up:cool:

Hi mate - I should perhaps have said cooler not colder. In any event they didnt want to budge off stock for me. They know I tow a 2 tonn boat too. There are views that its about the Bosch system running at optimum - fuel economy and emissions in particular, but Pedro I think and others in here run the cooler thermostats. I guess my point is you will have to ask exactly what they are selling at BOR to make sure it is in fact cooler than stock (ie opens at a cooler coolant temp). There was on guy on here that had a cooler one and found it ran hotter so went back to stock. I cant explain that BTW.

Cheers

On some sites the PEL500110 is named ''warm weather climate'' on others ''soft spring style'' so maybe that's suitable for down under :)

as far as i know it has had a rad flush and a new thermostat and water pump installed just recently from looking at the notes in the service history log book so now this is worrying me, i cant remember ever hearing the thermo fan kick in so im going to have to take it for a long drive and really crank the revs up to see if i can get that to turn on i guess so i make sure it even works, ill have to do the rolled up newspaper test also to see if the clutch fan is fkd also. but becides this all i can think of is a head gasket problem??

Don't torment your engine to check the cooling fan, remove relay R4 in the engine bay fusbox and bridge it's contact with a wire to see if it works or not(instead pins 30-87 it's a scheme on the relay)...fuse is F5 to check

As mine is a weekend garage project, ive given the car a good service and changed most of the fluids excpet for the coolant. Mine has a near new radiator in the last 6 months by previous owner, but im going to fit a new thermostat, and give it a flush just for my peace of mind.

As suggested by others, i think i might look into a seperate temp gauge for monitoring - do most have it attached to the engine block or actually monitor coolant temp?

In researching this i notive a bit of debate about using a lower temp thermostat as opposed to a genuine one.

What sort of thermostat are others running here? - would like to hear some feedback on this ....

If I were you, I'd get a new water pump.

Mine stank of coolant for ages and had all new bits EXCEPT the water pump.

Replaced it and only then saw it had a weep.

I.
