I think a hodgepodge 340 I purchased a few years ago had a cast iron water pump, so I thought I would ask if factory only installed aluminum (1968-1973)? Thank you.
Everyone has their own opinion (may be talking about plastic fan flex, not the same with a fixed metal fan). Two from internet search:
Shoot for about 1/2"-3/4" clearance from fan to radiator. The very important shroud should have 2/3 of the fan inside the shroud and 1/3 of the fan outside the...
When I see an aftermarket aluminum radiator in a Mopar muscle car I can't help but cringe. I don't fault anyone for using one, I am sure they are efficient units and probably an improvement over factory original units. I just never have been able to get accustomed to seeing them in the engine...
The '71-'74 rallye dash factory coolant temperature gauge only has two marks. Up to the first mark seems to be when the motor is considered "cold". Between the two marks seems to be considered "normal range." Anything past the second mark seems to be considered "overheating". That's how I see it...
After a year in storage, finally installed the Mopar viscous drive 5 blade fan (P4120758) to replace the fixed 7 blade fan. Did not have any cooling system problems, just thought it would be an upgrade. I don't know if it shows in the foto, but the aftermarket 22" shroud I installed some time...
I am thinking about bypassing the factory automatic transmission cooler (built into the radiator) and setting up a stand alone cooler for the 904 in my '72 Satellite Sebring Plus project car. Why? Plan on going to a higher compression motor to replace the current 318 and would like to take the...
On a non/AC car I guess hot water circulates through the heater core at all times, once the thermostat opens, right? Just wondering in the summer (or where i am nine months of the year) if it would make any difference in passenger cabin comfort to bypass the heater core altogether? Thank you.
The white rope caulking on my 72 SSP non A/C heater box was so disintegrated during disassembly that I can't be sure which channel or channels to place it in. Anyone have a foto, sketch, or clear description for me? (sorry, no foto included but I think you know what I mean).
And another...
It's another one step forward/two steps back today in Mopar Land. Pulled the plastic squirrel cage off the heater motor blower during my heater box rebuild. It was stuck a little, so used some WD-40. Well, it finally came off but tiny bits and pieces of the plastic center hub went flying. It...
Pulled out my thermostat housing to repair a seepage (1972 SSP 318). Autozone had previously sold me a thermostat (195 degrees). Referring to my 1972 manual:
From Factory Service Manual (7-8 Cooling System)
Thermostat
The thermostat is actuated by a pellet containing a copper-impregnated...
