Hoy hoy all, I know its been a while since I've posted anything. That's what having a female companion will do to ya. Priorities now have a filing system.
Have a query for the group. Let me set this up right... My convertible is doin' UA Parade duty again. Two years ago in my first parade, the 'bird managed not to overheat (thank goodness). But it was approaching the point where I'd have to make an early exit. Glad we didn't have to go any further.
This year I want not to worry about it. So, I've been thinking of plunking down $100 on the Kooler water pump from Ames.
Just wonderin' if anyone else has gone this route and what their result was/is.
Glad I thought of this before it got to late to do anything.

I bought a koolflow from Summit ,when my original broke, didnt change it much at all...a 3 core all aluminum radiator did it for me...dropped another 10-15F.....I had done lots of things to cool mine over the years ( fillers, gapping the impeller, timing , thermostst, carb settings,etc,etc) , little by little got it down from running 230 in summer to 200-205...now 190-195

By far the best investment to me was the aluminum radiator..... Everything else helps but the radiator did the job for me...

I've done everything under the sun but the side fillers. And I think those won't help much. Two or three years now since I went to a four core, from the stock three. That helped with delaying it getting hot. Gapped the impeller and divider last year. That helped some, and the Water Wetter didn't do diddly.
Just did some reading, and found I'd better check things. Seems I have the early '69 pump (4"), so the Kooler pump is not an option. Unless I change the pullys, but I'm not shellin' out $400 for that.

Flow Kooler worked no better on mine vs Perfect Circle.

they do.....I had one missing , installed it ,got me 5 F less

I had mine out last night and while idling down the dirt road to get back to the house after a 45 minute drive it actually cooled down. Aluminum rad, new water pump and no fillers installed yet.

I did the swap from a steel stamped impeller to the cast, and then beat the divider plate down till it touches the impeller, with the gasket in it cleared it. My hot running car with the temp. creep on the high way now runs stable 195-200 at 3000 rpm ... It used to go 220 and at idle it now runs 190 and never moves...

I had the same problem, installed a clutch fan & the upper fillers & the problems was solved.

I'm suspecting my desert cooler 4 row is full of poplar tree fuzz. We have so much of that fuzz in my neighborhood it looks like snow.
