What Inhibitor For A 903

Can anyone tell me what inhibitor I should run in a 903 also should I run any particular coolant.
Cheers

I'm still running Fleet Guard Compleat 50 in mine, unfortunately it is no longer available. After my last filter change and a hose replacement I topped it up with Gulf Western All Fleet Heavy Duty Diesel Concentrate. They claim this is compatible, and is designed for heavy duty wet sleeve diesels and the sca additive. I have been using the pre charged (3 unit I think) with sca fleet guard filters, but haven't been able to check the concentration in the system properly as the local supplier always seems to have out of date test strips.

I used to use Fleetgaurd DCA4 and got it from local Cummins dealer.

I just buy 200 litre Drums of Premixed Stuff off Cummins (Fleetguard).And run it in everything from the Lawn mower Up..
I still refer to It as TEC50.
But It's now called something else (not too sure what)

Go to your local KW dealer and use their All Rig pre-mixed coolant. Spin on a zero unit water filter. Top ups are done with the pre-mix. Keeps it simple.

It shouldn't matter too much mate, just make sure its a good quality one. It does pay to shop around, there are some that are good for half a million clicks and all that's required is a filter change every year to keep up the DCA.

just put a fleet guard wf2075 water filter and a bottle of fleet guard DCA65L and she'll be fine!
903's were around long before all the pre mixed coolant became necessary

Just bear in mind that one will have no anti freeze/anti boil protection with water.

Considering the negligible cost of coolant over tens of thousands or even half a million kilometres, I'd run a modern coolant and reap all the benefits...

if "one" needs anti boil protection "one" should be checking thermostats,water pumps,bleed lines and radiators!!

pre 1988 engines were designed to run on water with DCA additive.
the latest "modern" coolant from fleetguard that is supposed to be so environmentally friendly that us humans could probably drink it is causing lots of water leaks from pre 1988 gaskets and seals that weren't designed to handle the latest chemicals

...jeeeez newto .. and i thought i was becoming a bit of a hard arse!
