well today i took my radiator to the radiator workshop around the corner from my work (they are off watt road, in mornington)
$95, to have it "serviced" his word was "we'll pull it apart, clear out the tank tubes and the cores, (high pressure backflush i assume?) and seal it all back together"
since i just got my tax return i didn't mind paying that at all, and ive know gone from driving no more than 30 minutes or so, engine sitting at about 90degrees, creeps up with hard driving or highway driving,
to a happy engine sitting at 60 degrees!!! i drove it for almost an hour and it never went about 67-68degrees! couldnt be happier!
