Out here they need an extra or larger transmission cooler because of the temps we have, especially if towing, the standard cooler just doesn't cope with the extra load.

03-04 nicer finish as well, not just grey or brown.

I was told the injectors are different.ECU is also different
Also if you look at the LR engine spec,you will see MY 03 in auto has higher torque figures than previous D2's

I think the figures went from 315 to 340nm if my memory is correct.Power is the same.I have had both models & the difference isnt noticeable.

From what I've read and been told on here the later injectors work on a higher preshure.
Different timing chain and cam rockers to start with.

{The things I've learnt on here :eek:}

Cheers.

can any one tell me what their td5 does when you disconnect your coolant temp sensor wiring, while running at normal op temp, need to know to diagnose faulty sensor, coolant or fuel temp

Hey Baz
Had to replace my **** A/T oil cooler recently and asked if I could get a bigger one. I am already chipped to 140kw and want to go up from there and was told "no, there isn't room for a bigger A/T cooler".

Have you done this?
Cheers
Mike

Mike, I recently went to fit a P38a tranny cooler to a D2, only to discover the same problem. There is very little room, and the plumbing would want to be pretty carefully routed. I would give it a go with my own vehicle though nothing is impossible:), the customer didn't want to pay for the extra R&D time, which is fair enough:o

Thanks Justin,
That's a bit of a bugger... I've already got a bigger intercooler stuffed in there ;)

I did say nothing is impossible Mike:cool:

I came to the conclusion in the end that fitting it behind the grille would be the best place, modding the grille plastics accordingly. This vehicle however had a winch etc in the way which made THAT impossible. Definately feasible without one if you don't mind chopping a bit:D

Disconnecting the coolant temp sensor with the ignition on will cause a permanent fault to be recorded. The a/c fan will then always run whenever the engine is running until the fault code is cleared.

The fuel temp sensor appears to be disabled in Aussie (at least) ecus (certainly mine and lots of others) and the fuel temp defaults to 60 deg C.

The coolant and fuel temp sensors are identical and thus can be swapped. They can also be purchased at auto outlets as its a common Bosch sensor that's used in lots of vehicles eg Commodores.
