Swap the wires on the fan so it blows through the radiator. ?It will make a big
difference, and I'm speaking from experience. ?
Just a few weeks ago I got my newly rebuild engine back in the car and ready
for Drive Your Triumph Day with 4.5 miles on the engine. ?Going down the
freeway, it was?right at 190 temp. ?Then in town, and this was on a chilly
morning, I overheated at about 220. ?We opened the bonnet and the overflow
bottle was full, and my son asked me if it mattered which way the wires went on
the electric fan. Hmm, good question. ?My fan is on the inside of the radiator,
so with the engine off, we turned the key to turn on the fan and with a piece
of paper put up to the fan and it sucked it to the fan, blowing forward. ?My
son turned the wires around so it now sucked, and off we went on the Drive Your
Triumph Day drive, and the temp was perfect.
So yeah, swap those wires so is blows air through the radiator towards the
engine. ?I'd be surprised if that doesn't fix your problem.

My temp even on a 68 degree day in Florida today runs at the mark between
185 and 230. Assume 200 or a little higher? I have a stock four blade
metal fan and prev owner put electric fan on front of radiator with manual
on/off switch under dash. The electric fan blows the air out the grill.
Seems backward to me. Doesn't help cooling either way. Is there a
preference on the best alternative fan blade to use for better cooling?
Macy's hurricane fan? TRF Yellow blade fan? Other? Thanks in advance.
