that used to be my problem too. i really had trouble finding out what was wrong with it. BAKA MAHINA takbo ng FAN mo??

in my case, i thought yun nga. Lahat mahina ang electricity. lights were dimmer, aircon blower mahina din. i tried replacing my Alternator to a bigger capacity, (75 amps) and yet mahina pa din.

In the end, we were able to trace down the culprit... kulang lang pala sa body grounding. After adding some wires to body ground, everything went ok. My temp now rarely goes to half mark. when it does, either kulang sa tubig radiator ko, or im driving in traffic at noon time. otherwise, my temp just goes up just in between the 1/4 and 1/2 mark.

There's also a thread in clubmitsu discussion board about Earthing or Body grounding. you might also want to check it out.
