Looks like yours has an earlier radiator, the series 3 radiator has a more rounded top tank as seen in Sleepy's photos on page 4. The position or angle of the bottom pipe changed between 2a and 3. The top hose should be the same though.
My bypass hose is cut from a suitable Holden hose, $3

yeah i bought through fwd in brissy and i think it wasnt there fault just that someone has done a diesel conversion on this and id say the radiator was part of the conversion, along with the non original hose.

the bypass hose i just took of the top bypass bit on the thermostate housing and fitted it that way so all good now. specially the lights are woring a rippa as well.

it seems as though i may be keeping the work ute now so this old girl will be up for sale shortly, as i have a few pressing budget issues soon and may need the dosh at my most reluctantcy to sell it as it would be great to have as a round town bush/extra work behicle.

Before you sell it, run a 500ml bottle of 2-stroke oil (chainsaw/bushwakka/common or garden premix stuff) through a tank of diesel.
If you want, rather use about 100ml in a 20 liters.

The 2-stroke oil has anti-soot compounds that will clean any rubbish off the rings and valves.

If you're filling up with high sulfur diesel, you'll find the engine will be all coked up.

It's worth a try, and won't hurt.

ok thanks but at the rate its going now itd take a year to run a tank out seeing as its only moved from 1 side of the yard to the other when i mow, or into the shed to work on, thats kinda why i am looking to sell only cause i got the work ute now.
