Thread: D2 TD5 COOLANT CONFUSION

You've got a few things in front of you. Start by turfing the egr and cleaning the inlet manifold. If your not sure about which coolant is or has been in the engine flush it and fill it again. I recommend the nulon red oat (or any other oat) over the traditional green stuff. The hoses are a 100k km/5 year thing so if there's no history do them too.

Do you mean turfing the EGR?

I'm looking at at least blanking the exhaust manifold very soon. Is it really better to take it right out and get the pipe kit?

Will be going right over the coolant hoses on the weekend. I see these hoses as the easiest way of toasting a head in very short time if one lets go. As i said with the wife driving it she wont have a clue until it's too late.

Is it definately 50% concentrate 50% water. Should it be distilled water?

Think I better drop the sump and check the oil pump bolt too then. Ah, what did I do on weekends before Land Rover.

Sorry for all the questions but searching the forum threads brings more questions than answers half the time.

Thanks

Most use OAT red 50/50. Can buy it ready mixed to that,or can buy concentrate and break it down to 50/50.Use distilled or demineralised water.

I think it`s a good idea to change annually despite manufacturers claims.

In this thread it has e-mailed responses back & forth to Nulon,

Also a suggestion to earth your alloy Radiator!

If you are only topping up until you do the job don't waste your money on coolant. Just put water in it until it is fixed. Straight water for a short time will not do any harm, and as you still have coolant in the system in will just be a bit less concentrated.

Thanks for the feedback people.

Roverv8 seems you investigated this a few years ago. So has the green been OK. I'm guessing it must be or you would have a bit more to add about failures since. I think I'll change all the hoses and run green.
Does seem like having to go back to red brings in a whole new varient in chemical flushing etc. Etc.
This rig had a water pump and then a rad and then a fuel block all within 6 months about 4years ago but only 20k km since so I'm wondering now what coolant it ran prior to that now. I dont think its actually ever been off road either and has been serviced by Land Rover stealer and then specialists.since 05 so I'll just hope they all did what they were supposed to in that time.

My recently purchased D2 Td5 with 145,000 km came with a full service history, but from an independent, not a LR stealer. I have been going to ring them to find out what coolant they have used. I will do this and report back my findings.
