Holy ****,again.

Is your rad ok?

Getting hot all over?

I would get a compression test done before taking head off and changing block.

Ps,

You need to pay for your oil cooler kit

Payment details are in the thread.

As above,water pump will be worth a look.

Have seen plastic impellors crack on water pumps,they don't overheat at idle only when the engines being used as the shaft spins inside the impellor and doesn't pump any coolant around.

Best to keep things simple and remove extra things they take coolant.

Remove Hester matrix since they block quite often, just disconnect the pipes at the bulkhead and join them up.

Same with the oil cooler and egr cooler.

Remove thermostat all together.

So simply engine with two pipes going to each end of the radiator, they should rule out everything els if the radiator is new.

Doesn't mean it's Ok, I deal with plenty of relatively new parts failing down to manufacturing defects etc

Any blockages in waterways?

Before now seen mixtures of K Seal and coolant system cleaner clog up, fortunately in an overflow so no issues

Have you checked coolant flow around the components?

Checking for blockages.
