Was looking at this:

Iíve got K74 2006 Trojan

Does this radiator look ok?

As a non expert it dosent look too bad a job,

Any pit falls I need to be aware of?
Tips for refilling coolant?

Many thanks..

I would change the stat for a new one and flush the system completely.
Fresh antifreeze ready for winter, and a new rad cap,
They can be a pig to bleed up.
Raise the front end onto bricks or a kerb, you can remove temp sender to help the air come out.

Make sure all the pipework and mounting points are correct to yours, also the actual size . There are several different size radiators for a K74

Bit of an update,
Finally got a radiator had a right debacle with sizes, radiators being out of stock radiators being the wrong size and wrong radiator caps... the new radiator on.

2 quick questions
When I filled the radiator up had the engine running up to temperature I was expecting the coolant level to drop. This hasnít dropped and it all seems full. How do I know if there are any air locks in the system and how to I make sure I get them out. Had the heater running and it heats up. I did think this the heat temp out of the fan did fluctuate slightly but car temp held steady.

Any advice to make sure I donít have any air stuck in the system would be great.

Many thanks
Dickie

Easiest way to refill and stop potential airlocks is to have the front of the the truck raised ( on ramps , or stands ) and fill using the top hose. Have you run the truck in normal use ? If you aren't getting any movement on the temp guage then just check the water every few days .

And K74 radiators are a bloody nightmare to find the correct one ... so many listed on evil bay that are the wrong size lol!

Yer had it on ramps, have taken it for a short spin and the temperature didnít seem to go up anymore than normal. The bottom radiator pipe still has a bit of a cold patch on it so Iím hoping that the air will work itís way out.
Iíll keep an eye on it. Thanks for the help..👍
