Outer Limits 4x4 Board

Intermittent cooling problem where the needle will climb past half way.

It's okay when it's moving at speed, it's just when it's crawling.

Oil appears to not have any water in it so I am assuming the head gasket is ok.

It's not using any water so I am assuming the radiator itself is water tight.

Just wondering if I should I start by:

1. Flushing the motor / radiator etc with garden hose

if that don't fix it

2. Replace thermostat?

if that doesn't help

3. Replace the radiator and hoses?


Any suggestions or common faults problems etc would be appreciated!

Thanks guys

Does it have a viscous fan hub? If so id be overhauling it

That it does!

I'll check it out, cheers mate

Definitely check fan hub, I would also suggest removing radiator and getting it checked/tested/cleaned.
