91 NH Wagon questions

Hey, I bought a 91 NH Pajero wagon, turbo diesel. Got it very cheap, and I got it off a woman who inherited it, didn?t want it. The only thing I have had to do, new wipers, and a new set of tyres. I know nothing about these cars, but I recently took it on a camping trip and a bit of 4x4 work, which bought up a few questions that I?m hoping someone may have answers to...

1. Is there a clutch fan available for these little turbo diesels? While climbing some decent hills, both on and off-road, the temp gauge really started to climb, and my fan seems to be a fixed one.

2. On the dash, it indicates four wheels and centre transfer lock. In 2WD, the front wheels flash. Is that normal?

Cheers guys.
