Diesel Cooler leak

[sln8458]

As the title, I have a diesel leak around the cooler somewhere

Simple question(s) to start with:
If I remove the complete cooler from the car, will the remaining connections on the car leak?
If this is the case, whats the best way to stop them leaking?

I've seen a 'new' cooler on ebay (£150+p&p) is that a good price? Is it worth having one to do a simple sway over, then look to repair the old one?

HI Steve.
It is usually one of the hoses leaking or the valve, which you can replace with one from a Freelander 1 TD4 with the same engine, it resides in the engine bay on the FL1 so does not get damaged.

You should be able to takes the hoses off and not lose to much fuel, same for the valve.

Thanks Steve,

I stuck my head under the car last night and everything is covered in diesel, hence my thoughts on pulling the cooler out completely to work on it.
Also I suffer badly with diesel fumes, they make me physically sick (obvious then that I would have a diesel car!!! )


Thanks for the links.


PS. I assume that as this is in the return line to the tank, any air that gets in during the repair will subsequently clear to the tank when the car is next started?

To ascetrtain the likely cause of the problem, it is best practice to fully clean the rear facing area of the cooler using brake cleaner spray, a tin of this should be enough - before doing this, I would place a container beneath the cooler as there will be plenty of fluid dripping off. After everything has dried off, make checks to the hoses and their attachments as I have had a few hoses to replace of visiting cars, if they all appear to be ok and the metal pipework is sound, the most likely cause would be the plastic valve body, which usually can be found on a impossible bracket to remove from. What happens is the securing bolts suffer with corrosion which expands the bolt material beyond the abilities of the plastic valve body that they pass through, this in turn fractures the casing and allows the leaks. As Arctic states the Freelander2 has the same valve, but in a better location, and unlikely to find one that has defects. The replacement of the valve is fairly easy to do apart from detatching it from the rotten bracketry, there will be fuel losses but you could consider changing one pipe at a time to minimise exposure to the reaction you suffer with when in contact with raw fuel.

Can anyone confirm if this is the correct cooler for the Facelift 75's please?

sorry about the image size

I can find nothing on Rimmers apart from its for a Range Rover

It look to be ok so does this one below.

Spray your with engine gunk cleaner, and then jet wash it off and you should find the leaking hose most of the time it's the end of the hoses that have flared with age, you can trim them and refit with a good jubilee clip.

Hopefully you've sorted it mate, a couple of the connections can be tricky.

Hi Andy,

Yeh, they were probably the ones I gave up on, couldn't get my stubby fingers in there. I ended up cutting some of the old pipes on the cooler. Between the 'T' and the valve, also the 'T' and the upper connetion to the cooler, plus the larger connection to the valve. Then able to slide the cooler out of the plastic frame. Remove the frame and the rebuilt the new cooler in situ.

Diesel down my arm, coat.......
