Thread: Anyone's fuel cooler have a thermostat and spring in the end?

Well for better or worse I decided to leave it out. I guess no thermostat is better than a broken thermostat. I will see if they are available somewhere during the week.

All back together and not leaking so far. I will be keeping a close check on it.

It was really good to replace the o-rings as the cooler had been previously bodged with silicone sealant.

Can I just leave it out?

Thanks

No. That thermostat is an integral part of the system, designed to supply an adequate supply of coolant to the fuel cooler, without it, I suggest the life of your fuel pump may be reduced. Next time you go on a long drive, place your hand on the fuel tank. Also, by removing that thermostat, you could possibly interrupt the designed coolant flow, with dire consequences. The TD5 coolant system is a different beast to all that went before it. You really must purchase a RAVE DVD , & get an understanding of the vehicle. Cheers, Bob

I rebuilt mine today and would suggest that removing anything that changes the spped of the coolant flow would be "not a good idea".

However if you want to cool your fuel further it would not be harmful to add an additional cooler. I services a 2009 diesel hilux recently and observed a very nice air/liquid fuel cooler mounted under the passenger side floor. Very tidy indeed. I am going to do some searching during the week to see if I can find one aftermarket.

Probably no different to fitting a B&M or PWR type cooler, just seemed a good idea for the Land Rover due to the temps he fuel reaches in the tank.

Food for thought.

Removing the fuel cooler thermostat could only increase coolant flow to the fuel cooler thus cooling the fuel more.

Feel the the temperature of the filter near the tank to confirm.
Mine runs hot to the touch.
Rave states the fuel temp runs over 82c
I reckon it will be fine for a while

Hi All, thanks for the input everyone. I will chase around a bit during the week and see if I can find a replacement thermostat, without having to get a whole new cooler. The input and advice is much appreciated, these are complex engines and I'm learning as I go on this one.

Any leads on a place to get a new thermostat would be great

The 04 td5 on had a redesigned plate type fuel cooler and no thermostat...

Thanks for that link Northiam, not that i'm going to run off and buy one if I can at all avoid it, but good to know that the thermostat was redesigned out!

I have tested the thermostat which was in there, it did expand a little in hot water but then jammed in that spot, I'm happier to have no thermostat than the possibility that it might jam in the closed position.

Cheers
