1969 383 Water Pump

[bobfake]

Hi all,

Working on low rpm, hot day in traffic cooling. Ordered a Mr. Gasket 4367 thermostat. 1968 383. Regarding water pump, just need a quick brain check here...back when I got my first couple of Chargers in high school (1977'ish), I seem to recall the water pumps were one-piece units. What I am seeing now is that they are two piece units? A housing and the actual pump?

I recall this one piece (pic for description only):

Versus the 2 piece like this one:

Just wan to confirm I need the two piece unit?

As always - thanks in advance!! Bob

THe 2 piece is for a big block.

Thanks...I had a 383 in both of my Chargers years ago and thought they were one piece. Maybe back in those days, both parts came pre-assembled, making me think 1 piece...

They never were one piece. All B, RB, Hemi had the housing as one part and the pump as another.

Thanks! So I suppose there’s no reason to remove the housing…just replace the pump. Looking at a Flowkooler pump…

Correct, you only need to replace the pump. If you get a Flowkooler pump get their recommended thermostat as well.

Hi all...I know our cars running hot can be an issue and there are many schools of thought on this, but I wanted to share my experience.

After I installed the Flowkooler water pump, my Super Bee still ran quite hot, especially in beach traffic around here. I just want to put out here that I installed an ECP radiator with twin 1500cfm fans with shroud and that did the trick. Just back from Chrysler Carlisle and even sitting in beach traffic in Rehoboth on Thursday for about 45 minutes, sitting in a long line to get into Carlisle sand hitting some beach traffic coming home today the Bee never got above 220 degrees.

I also had them weld a bung for the temperature sensor for the fans.

Anyway - just wanted to let folks know what worked for me.

Hi Bob,
Are you running A/C as well with this set up? I have a 383 with Vintage Air. Thanks.
