OVERHEATING
#11
I'm Running V-Belts, This engine never got hot when it was in the Granada. I will pull the cover on the "new" pump and look at it.. I may depending on what I find post pics of the two. I do know the "new" pump does not have any casting numbers on it at all I guess that because it's not a reman. I may try changing to a 24" radaitor as well. I can also say DON"T BUY PARTS FROM AUTOZONE FOR THESE CLASSIC CARS I Have had nothing but issues with their parts.Angry

I have to agree, the people at Auto Zone only know what the computer tells them. Otherwise 95% of them wouldn't know there azz from a hole in the ground! JTS 71 Mach1

Something else to think about: A 4 bbl carb will get better gas mileage than a 2 bbl, because the front jets are smaller than a 2 bbl. as long as you don't kick in the back 2 bbls.
A 2 bbl needs larger jets so it can run at high rpm.

Remove the thermostat and see what happens.

I used a "failsafe" stat, when it overheated it locked the stat in the open position. I noticed that at low RPM the water circulated fairly well, with higher RPM's it tries to push the coolant out the filler neck. I thought at first the system may be "airlocked" but if it was the coolant would not circulate at low rpm's it would try to push the coolant out as well. SCo_hmmthink

I pulled the "new" pump and took off the cover there was about 3/16" to 1/4" gap under the impeller , when I checked the original pump there was only about 1/64 gap,( big difference) I changed the intake also but noticed my new brake booster was hissing under the dash so I took it off and sent it back to have it replaced. no brakes so I will drive the car in a few days. I did run it for about 30 min and it never got over 160 DEG. I will know more after I get the brakes going. I have 2 temp units on this intake 1 in front and 1 in back I want to see if one end heats up faster or if the temp stays consistant, that will tell me if it is a circulation issue. Pray

It will be interesting to see what the story tells.

I'm still waiting on the brake booster to get here, almost 2 weeks and no boosterAngry hopefully it will be here today... I'm ready to see if this car is fixed : changed the pump,changed the stat, replaced the shroud (the other one was broken), straightened all the cooling fins in the radiator that were bent, changed the intake, replaced the 2 1/2" fan spacer with a 1 3/4" spacer, set the timing to 4 DEG btdc. we'll see what it does after I get the booster back on.Pray

As for the lower hose that Steve inquired about,My 428 would run the same , but as the rpm went up the pump would suck the hose into itself. dose it have the spring in it, if it came from a cheap parts store it might not be there, this might not be notice while driving,
