td5 coolant

[Bauke]

hi, what is the correct land rover part number for the collant suitable for the td5 as i have 5 bootles of genuine coolant here but not sure if it the right one any help would be much apreciated

[Naks]

I wouldn't worry about always getting 'genuine coolant'.

As long as you use a 50-50 mix of good anti-freeze & distilled/filtered water, you will be fine.

You can buy the ready-made coolant from auto parts shops, or you can buy the anti-freeze and then dilute it yourself.

I would say use the genuine stuff that you have and once that is used up, just get a good quality anti-freeze and dilute yourself, and keep a bottle of the ready-made in the truck at all times.

Also, it is a good idea to install a Madman-type engine monitoring system, it will warn you of coolant loss way before your Td5 cooks - it is prone to do this within minutes of losing coolant.

Make sure it is OAT coolant, not Glycol based.

[Pedro_The_Swift]

and OAT coolant is a nice red/orange colour. There is a reason LR specify OAT.

[justinc]

bloody OAT.

Don't use it Bauke:mad:

I'll start by ordering you a radiator, a heater matrix and some O rings for your fuel cooler.

Clean it all out and use Glycol based off the shelf green stuff that exceeds and covers GMH spec and you'll be fine.


Didn't we already have this conversation??

And MR auto here advise the same.They did mine last time with a Valvoline green product,G5 or something similar.These guys are LR specialists.

Actually, I DO know the part number,

'LRSdontuseititisrubbishandwillruinyourcoolingsyst em110032'

Sadly, it is still available from LR:(

:D:D:D:D

Justin.
The TD5 cant be simply flushed to rid it totally of coolant.
When my clutch was done the repairer used GREEN penrite coolant assuring me the OAT was fully flushed.
When I did my cooling system rebuild last week,1000ks since the green went in the coolant was more redish than green.
The seperate section on the radiator that has connects to the fuel cooler was red,hadnt even mixed with the green.
I flushed many times with water before stripping the cooling system and again after.
I realise there are those who like/dislike OAT.I believe all these TD5 cooling system failures we hear about,oil coolers particularly are caused by running a combination of the red and green coolants which are incompatible.
I was VERY impressed with the grey coating on all visible alloy components that the OAT was in contact with in my engine.For an engine with 252000ks/almost 12 years under its belt the components are in excellent condition.

I don't disagree as such with your experience Andy, but I flush these TOTALLY, and have never had a problem with mixing of fluids yet. From what I have seen, over the years I have worked on these engines, including the V8 D2's, where OAT has been responsible for external leaks from as early as 60,000km:mad:, is that IMO OAT does more harm than good. MY opinion only.

I'm glad yours is in such good condition, its a good start for the longevity of the vehicle.

MR Auto Are currently using HOAT..... or thats what they advised me when I had to do a job on a td5 that they had last serviced.

i've used the hybrid stuff too in the past at a customers request. tbh i would just use glycol in that instance anyway for all the hasssle and difficulty in obtaining oat in out of the way places etc.

Oats not that hard to find.... you can get it up on the cape now.....

[Rosscoe68]

you can also get crocs up on the cape, but as with OAT who would really want either of them in your LR

[Blknight.aus]

Everything has its place.

OATs there for a reason and crocs make damn good eating and footware..

Ive had both in big red and AFAIK big reds still running OAT.

So they have changed,was definitely valvoline G-05,green stuff,18 months ago when mine was last done.They had used it for a while on all TD5's.

[Blknight.aus]

valvoline g-05 is HOAT.

Valvoline.com > Products > Zerex > Antifreeze Zerex > Zerex G-05® Antifreeze / Coolant (http://www.valvoline.com/products/brands/zerex/antifreeze/42)

the generic blurb

http://www.valvoline.com/pdf/zerexg05.pdf

the spec sheet.


The Problem with it IMHO....

ITS GREEEN. as are most of the new HOATS and some companies are marketing their HOAT as plain old antifreeze or long life coolant which means some people are using OAT spec coolants and not even knowing it.

IT also means that some shadey grease monkies are using ethyl glycol and passing it off as HOAT.

IN Theory...

HOAT has all the advantages of OAT, can be blended with OAT or Ethylglycol type coolants as required and has the "skinning" properties of Ethylglycol that everyone loves because it means you can ignore what would otherwise be an insignificant leak.

My td5 has red oat in it and allways has from factory and allway will..
