Already time for a cooling system rebuild.

Picked up my '74 Swinger (318) from the paint shop a couple of weeks ago. Drove it to work last weekend to repair an exhaust leak, then my dad wanted me to pick him and take him for a cruise down the Natchez Trace Parkway. The whole time, it's running fine. Bought new alternator, A/C, and power steering belts on my day off and drove it to work this morning so I could change them. About two blocks from work, the cap on the overflow tank popped and out spewed coolant and steam. Heard a groaning noise as I pulled into the shop, maybe the water pump?

Since the car is now stuck at work, I don't have the luxury of time to troubleshoot what went wrong, so I'm just going to replace/rebuild everything. There's a radiator shop nearby we use for that work, so that's easy. I've been on Rock Auto looking at the various water pumps, thermostats, etc., available. Being a Mopar newbie, I'd like to ask what do you guys recommend for replacement parts?


If you are going to change parts, I’d buy either the Milodon or Flowkooler high flow water pump and a Stewart Components high flow thermostat.

It’s not that much more money and it’s better products.
