Thank god. It's not as bad as I thought. My car has been serviced by one of the coolest-headed mechanic around. He take a look, and found that just the radiator bulkhead (the top part-where interconnected with the cover) is causing the problem. Replaced the top part with quality-graded spare parts and everything turned out alright. He even checked the fan and found that the cable is a little loose. A quick rewiring solved the issue on the spot.

And the most surprising thing was the charge. It was only RM 150, 100 for the bulkhead cap, 15 for the coolant liquid and lastly RM 35 for labour. Luckily for me, I did have the cash during that time and paid him off since his shop doesn't accept any credit card. What a nice chap. Bless his shop. Test drive the car and run around - looks fine, temperature doesn't just jump out anymore.

Alright, one problem solved, now towards continuing the darn exam!
