Hi all,
I have just become aware  Embarassed that with the 4.2 TD LC100 [u]AUTO[/u] the auto ATF goes through the bottom part of the radiator to cool and that this cooling section is separated from the main rad by a thin metal partition. If this corrodes through due to lack of corrosion/electrolysis inhibitors in the coolant (passage of years/miles), total engine/gearbox carnage is most likely to ensue  Shocked My coolant was last changed a few years ago so it needs doing for peace of mind/£ implications.

My question is - Pink Super Long Life or Red Long Life? I understand that Pink is bad for older vehicles - mine is 2001:

"It is generally recommended that you use Toyota Red in older vehicles. This is mainly due to the fact that older Toyotas usually have non-aluminium radiators and Pink is not formulated with the inhibitors necessary to protect them. The Red Long Life coolant had molybate and a triazole to protect the metals (copper, etc.) in the older radiators."

So, does anybody know if a 2001 TD LC100 4.2 Auto has a radiator with a metal composition OK for Pink or should I use Red to be safe?
TIA Brian

Wrong section. This is the 90 forum. We don't know anything about your big lumbering beasts here.

(Toyota red... or whatever the original spec is. It may be a rip off but its what nature intended)

Ok, OK  Embarassed  - I realised that just after the finger hit enter! Can't see how to delete posts (I have tried FAQ etc) but now in the Big Lumbering Beast forum!
People with small ones please IGNORE THIS POST  Laughing TA! Brian
