The old green stuff is technically called IAT (Inorganic Acid Technology) coolant. Dexcool is OAT (Organic Acid Technology). It is not compatible with IAT. If it becomes contaminated it should be flushed ASAP, as you said. Also, the additives package will not protect copper, so it can't be...

In my experience, overheating at idle and in-town, but ok on the highway, is low coolant flow at low RPM. Sounds to me like you've addressed the obvious with the flex-fan and shroud. I tried that and they didn't help either. Your underdrive pulley could be the culprit in your case. Some...

What do you have for water pump, water pump housing and thermostat? Where is your base timing set? Do you have the vacuum advance connected, and to a timed or constant vacuum source?

Is the radiator you're looking at a 26" rad for the HD cooling option? Did they offer that option in 1965, or just the standard 22" rad? Can you post a link to the rad you're looking to purchase?

The cavitation problem would be caused by shear applied to the fluid between the moving pump vanes and the stationary housing. The shear forces would cause a low-pressure region in the boundary layer which would cause steam bubbles to form, and would be worse as RPM increases as you say...

The factory 26" rad used a different radiator support. You would need to drill new mounting holes in your rad support to fit a 26" radiator. Your cooling system would hold more coolant, but the opening for airflow would still be 22". For awhile it was popular to mount a radiator from a Ford...

The actual flow rate is throttled by the thermostat. This both regulates flow to try to maintain a constant temp in the block and also provides a restriction which creates high pressure in the block, which are both good things. The only downside is that the water pump pushing against a...

Also remember there have been issues with some aftermarket aluminum water pump housings. The inlet connection on some of them are restricted, which has caused overheat problems for people. I am running an OEM cast iron housing, so I knew that wasn't part of my overheat problem.

I believe that's the one I have, Bill. I recommend it. Use with their high-flow thermostat.

...with a stock engine and cooling system. With recored or aftermarket radiators, rebuilt or upgraded engines and altered ignition timing and all bets are off. My first high-flow t-stat was a Moroso because it was cheaper than the Mildon. That t-stat failed open and I wound-up replacing it with...

I posted about this on the C-body Dry Dock years ago. I had a pump like #2 on my 451 stroker. Always had overheat problems at idle and stop-and-go traffic. 3-core 22" rad, Flex-a-lite s/s flex fan. Added a fan shroud which did not help. With the fan shroud it took longer to get hot, but it still...

Apparently the 65-68 C-body A/C heater core was also used with 66-70 B-bodies. Google turned up the following, plus some eBay hits: Restoration - Mopar Heaters | Original Air Group Heater Core 1968-1970 B Body 1965-1968 C Body W/ Factory A/C - Bouchillon Performance Engineering Glen-ray...

If your car doesn't have A/C then there's a good chance that the upper hose won't work for you. See my comment above.

When I needed rad hoses for one of my Chryslers with a 26" rad, I looked them up on either Gates or Dayco website. I was surprised to find that the upper hose part number also cross-referenced to Ford fullsize vans, so it was easy to get. The lower hose I think needed to be ordered in but it was...

I haven't shopped for it in awhile, but I did buy it under STP brand and a store brand called "Autolab". When I was researching, a lot of people had good things to say about the GO-5 and it has good technical info online like the PDF that I linked to. I haven't seen similar specs published for...

I have done a lot of research on this topic. Regardless of colour, most coolant is still ethylene glycol. The difference is the additives package. There are 3 basic types: IAT (Inorganic Acid Technology): This is the green stuff that we are used to running in our old Mopars. It's actually...

I can confirm that, for 1966 Chryslers at least, there were different rad supports for 22" and 26" rads. Also, the HD cooling system which got you the 26" rad was separate from the A/C, but often ordered together. Non-AC car with standard cooling system got a 22" rad without fan shroud. AC car...
