2.8 CRD Sludge in water

Anyone know why I have a cream coloured sludge in my water reservoir?

It is normal for HOAT coolant to do that. If you want to clean the tank, pull it and clean it with Prestone Super flush.

That really does look crappy.


It looks like a full flush and cleanup is in order. I have not seen one look that gunky before.

The CRD section at lostjeeps has a fair amount of info on how to flush out the system.

Its a straight forward job, dropping the old coolant , undo the radiator plug, take off the lowest coolant hose at one end.> replace fluid with >> eBay item number:

3.7lt @£60 I would need x4 of those to refill my coolant thats £240!!!!!

I think a 5year Ethlene Glycol will be OK @ £18 for 10lt at Eurocarparts will do the job!

What you describe above is just to drain the system I need to flush out that sludge!

Is this Ethylene Glycol HOAT?....I cannot find this out on Google

Make sure you only use HOAT antifreeze or major damage will occur

I would concur with Billwill. It really needs to be HOAT, not regular plain old ethylene glycol. This is an item you don't want to skip or substitute on at all.
