I have 75K so I am willing to replace the old water pump and thermostat to complete a totally new cooling system (Radiator replaced about 3K ago).

BUT, I'm starting to think it's my fan. It doesn't kick on now that I actually take a good look. Should I just replace the low speed fan relay? What is the fix for this problem?
