perentie coolant

[charlie a]

Hi all - My 110 Perentie has a sticker saying the vehicle uses Nalcool Maximum coolant.My questions are whether this product is readily available or whether there is an easily available substitute that I can use to either replace the Nalcool or, hopefully, just top it up as required.

looks like Nalcool has a number of different coolants. Anyone know which one was used in the Perentie?

I know my local NatRad said he would refill with N2000 when I asked about it a while back.

I am in the process of benchmarking the cooling system in my Perentie, part of which will be changing the existing coolant. My radiator is stickered stating that only Nalcool Maximum coolant is to be used in the Perentie's cooling system. A bit of Googling put me onto a firm called East Coast Lubes in Brisbane who in turn referred me to a firm called Southern Cross Lubes in Melbourne who deal with NSW. I spoke the technical/lube engineer (a very helpful guy) who advised that Nalcool Maximum was no longer available, with the replacement coolants being Nalcool NF48C (concentrate) and Nalcool NO5 (the same product but premixed at 50/50).

Apparently the 2 Nalcool coolants are a high quality heavy duty diesel ethyl glycol based coolant with corrosion prevention additives for both cast iron and aluminium protection. If my engine is anything to go by (12/1988 vehicle build) it does an excellent job; the fluid that came out after being run with a Nulon radiator flush in it was near perfect - no rusty fluid, and the amount of sediment and scale wouldn't have covered a 20 cent piece. The inlet and outlet of the water pump and the outlet of the thermostat housing are clean as a whistle with no corrosion or tuberculation evident. In addition to the anti-freeze properties of the ethyl glycol the additives supposedly deposit a coating to all internal surfaces of the block and cooling system which I think is the purple deposit I could see inside everything.

Now for the bad news - both the concentrate and the premix can only be bought in a 20 litre quantity, with the concentrate costing $190 - $200 and the premix costing $140 - $150 via a distributor.

Based on how good a job it seems to do it I will more than likely shell out for some of it - probably the concentrate - but it will hurt! If any other Perentie owner local to Newcastle/Hunter Valley would like to split a drum I'd be interested......

Cheers, Dave

sounds like it's worth using. Also sounds like you'll want to pair up ( or 3 people would be better - should be enough concentrate to do 3 cars) with others and see if you can do a deal with a radiator shop to do them.

Obviously you can DIY; I've had good results with having a proper pressure flush done on the system, which is something only a shop can do.

goto kmart, get 2 of the tectalloy coolant 1l bottles, buy 2x 10l bottles of water.


thats what you need to look after the suzi.

flushing is done in a similar manner and a pressure flush gun can be purchased from supercheap on some days, a good tool store for around $90 and you'll find about 8 different uses for it once you have one and work out how it does what it does.

you need to have a semi decent air compressor to use it.

Thanks for the info on the nalcool as we use it at work.


We have used the afloc brand till last year, the local agent sent one drum of NF48C that was labelled ready to use to and another with recommendation to add deionised water.

Are people over thinking this? Just get a good quality coolant like Castrol or something. This is not a Land Rover engine that is going to warp a head in 20 seconds or corrode a part if some super space shuttle designed coolant isn't used.

I think that's what Dave was saying in post number five above

there are several tectalloy coolants

which one dave?

Have you considered waterless coolant
