Thread: What coolant do you run in your RRC?

1) Tectaloy 60 or 90 or whatever the green stuff is.
2) Because I can get it up here!

bmw branded blue stuff

cause that is what the previous owner was using and some concentrate came with it



ps cant look at the details as it is in the shop getting a transfer case swap...

Caltex green concentrate mixed with demineralised water. Because I keep it at work.

The GREEN stuff, Not the Cheep Brands, at highest concentration suggested and mixed with de-mineralised water.

Because it's relatively cheap to replace often, and LR recommends it, as did VW/AUDI and it performed perfectly in my 600K Passat... and ANY leaks are easy to find with a UV torch/light source, fresh or dried tracks AND glycol has a most distinctive odour...

Tectaloy 60
That is what I am currently using. The premix.
I bought it because it mentions "protection against aluminium corrosion".
It has gone off and I will be refreshing the coolant. I could continue to use it. It is a type B conventional coolant.
Tectaloy 90 & 100
Type A organic coolant. The green is silicate, phosphate & amine free.The red contains Ethylene Glycol 369g/Litre.

I assume I should be using type A and not type B. Would this be correct?

Now, I have a few bottles of Penrite concentrate. It is green, type A HOAT.
7 YEAR 450,000KM GREEN CONC
350,000 KM GREEN CONC

They also make a type A OAT.
7 YEAR 450,000KM BLUE CONC
8 YEAR 500,000KM RED CONC

Now, I have a number of aluminium block vehicles with copper/brass radiators and, now doubt, steel bits. Sixes and eights.
Would these motors have any issues with the Penrite coolants listed above?

Yep. Used to use that all the time on Minis. Back when times were simpler.

Blue mb coolant aka febi lemforder vaico.. because i have enough bottles of it.

I use the pinky-orange stuff, as it's meant to be better for the alloy parts of the engine. As I understand it, the green stuff is meant to be for iron or steel blocks and heads.
