coolant

[LRO]

Hi
What is the best coolant to use in the 4bd1:confused:

Afloc..... if you cant get that almost any ethlyglycol based coolant will do the trick providing ou keep it in the right blend percentages.

You can use the OAT type stuff as well providing you give the entire cooling system a thorough flush out.

The OE spec was soluble oil!!! :o:D:eek: So any ethylene glycol based coolant would be an improvement.

dont knock soluable oils as a coolant addative, on old cast iron on brass radiators engines or boiler type engines like the southern cross AK series of stationary engines its hard to beat as it doesnt mind being cooked or boiled as much as some of the new coolants...

I use Fleetguard Compleat premix in 20 Litre barrels.

That reminds me JC did u ever find the vehicle with the blue coolant in it? :eek: :oops2::Rolling::Rolling:

I started using it in my 11m cruiser (7L Turbo Diesel) and have continued using it in the TDi 300. I have no reason to suspect it wouldn't excellent in the Isuzu.

Cheers,
