    Since my '64 is running warm these days, I'm looking for ways to bring the temps down (I'll be installing a fan shroud tomorrow morning). Has anyone used Water Wetter, or any other coolant additive, that helps to transfer heat from the engine to the water?

    I have, and do, every time I change coolant (2 years). I also added a shroud about 4 years ago. I couldn't tell you which of the two made a difference, but I never get over 1/2 on my gauge anymore. I figure why not- the science sounds right.

    With only a 2 row radiator there's not much room for error, the shroud will help. I tried water wetter in my racecar and found no measurable difference, but it's cheap enough to see for yourself if it helps.

    Do the shroud first. See how far it helps. If you think you need a bit more, then do the additive.

    That's basically what I decided. I have the shroud in-hand, so it's going on, no matter what. I will be interested to see what changes with the shroud, because I'm not using one with my 352, and it never has overheating issues, even though the FE is known to be a hot engine. 'Course, the radiator is huge!

    I'll post my post-shroud results tomorrow.

    Right there. "'Course, the radiator is huge!" That's the difference between a full-sized truck and a car-based pickup, the amount of room for a radiator. The mid-Sixties Ford cars all suffered from a small, relatively speaking, core support opening. So, to maximize cooling, you either used a thick radiator core, a fan shroud or both. And you may want to spend some time making air dams that push the vast majority of air through the radiator core, shroud and fan, in order to maximize the cooling effect.

    If possible go with the largest (widest) radiator you can. Running a 4 row aluminum on the 74 and a 3 row on the 79 and both have shrouds with a clutch fan sets up. No issues. Additives to me all seem like snake oil and are only a "band aid" fix at best.

    I tried the Purple Ice snake oil today. No change. :( I ordered a 17" fan, which should arrive by next weekend, and will hopefully fit my new shroud.

    A factory type 3 row radiator will cool that thing just fine, even without a shroud. Ask me how I know. ;):D

    Ditto on the factory 3-row on a 65 289. No shroud and no issues. Even with add-on air.

    Just my 2 cents, Make sure your coolant is at the right concentration, too heavy on coolant mix is as bad as as not enough
    heat transfer is compromised use a coolant tester to see what your concentration is.

    That's what I did this last round. I know, lazy. But it got it done, no muss no fuss.

    It's not lazy just smart. No guessing no buying distilled water to mix or using tap water and contaminating your cooling system.

    Tap water? TAP WATER?!?

    When I got the 'chero last October, the first thing I did was to change the oil and radiator fluid. Unfortunately, the radiator fluid was straight water, so I will never know if it was distilled or from the hose (my money is on the hose). But you roll the dice when you buy a classic, because you really have no idea what the previous owners did during the past 50-ish years.
