Hi sorry if this has been asked before but can I use the thermostat from the 740d as a direct replacement on my 2002 FF.i would sooner use this than mod my housing.If anyone can go through fitting the 740d stat I would be very grateful
Thanks

Did mine a few days ago with the 88 degree stat, mine has a blanking plug where the sensor would go. No issues running without the sensor.

Have read issues surrounding excessive heat due to 105 degree thermostat fitted to 4.4 engine, have just ordered
Thermostat Housing aluminum type of the the bay of plenty 08.10.052 11531720173 from doctor_car for £12.50 and picking up 88 degree thermostat from eurocarparts.
hope that helps

I bought this stat

No problems found with fitting it.

Thanks for the replys
Have you noticed any difference with the new stat fitted
Regards

Much quieter, and the pipes around the rad are no longer rock hard. I needed my stat changing anyway so it would be a positve thing to do in my view.

Re rock hard hoses, what is the pressure rating on the coolant reservoir tank, 140 or 200kPa (look at the number underneath the cap)? Ron B. VK2OTC

Caps rated at 200.

I'd suggest changing to 140 kPa p/n PCD000070

Referring to MicroCat, it was changed to 140 quite early in L322 production.

See an earlier post of mine:

200kPa and 140kPa, not psi. A 200 psi cap would be about 1400kPa or 14 bar (using the approximation of 1 psi = 7kPa)

Use the 140kPa cap.

Mine had a 200 but was changed to a 140. If you look at Microcat, you'll see the 200 was for early models.

PCD100200L 1 CAP, L322 RANGE ROVER to (V)1A001049
PCD000070 1 CAP, L322 RANGE ROVER from (V)1A001050

None under my tenure. A year of ownership.

140 kPa = 20 psi
200 kPa = 29 psi

The 140 will stress your cooling system less.

The 200 will allow a higher temp before boiling occurs. Ron B. VK2OTC
