History:
I have a 67 318 with factory A/C in my 67 dodge charger.
When I got the car going again it never ran over half staff on the factory temperature gauge. It did work and sweep from cold to about half staff so Im pretty sure it worked.
The motor had an odd vibration that I had accredited to a shitty balance job during the rebuild of the motor in the 80s. This after replacing driveshaft u joints having it balanced and verifing correct torque converter was in it and then having rims/tires balanced. It also did it in neutral at a steady RPM.
Getting on the freeway and I hear a noise which turned out to be my fan belt going awol.
The vibration went away.
I watched the temp and it started to climb.
I drove about 2 miles to my house. Car never puked coolant.
The impeller on the water pump had broken and cracked the housing.
I got lucky, nothing came apart.
The car has factory clutch fan setup and shroud.
The radiator has been recored.
Here is the dilemma.
I replaced the water pump with a new one that was special ordered as it seemed to be specific to 1967 and specific to a car with factory A/C.
At the same time I installed a new fan clutch (hayden) and a 192 degree stant thermostat along with new upper and lower radiator hoses. Also add dexcool coolant, replaced all belts.
On the test drive my heater hoses blew apart. One week and three car part store circus acts later, those are replaced.
Topped off the coolant.
Now when I drive the car the temp gets up to about 3/4. It hasnt climbed past there and the car isnt puking any coolant. The motor feels hot but it always has felt hot to me. Hell its FLORIDA. Its always hot and muggy here.
The motor also does not ping or hot start or anything. Drives just like it used to just that the damn temp gauge climbs.
I looked at the oil and also pressure tested the cooling system suspecting a possible head gasket issue. Everything tested great. Motor runs like a top.
Im starting to lean towards the water pump being wrong. Unfortuneately for me and I dont know WHY i did this but I threw the water pump I took off, away. It was not need for a core as I bought a brand new water pump not a reman. That being said I was unable to stare and compare.
Does anyone have any experience with this or can possible point me to the correct water pump to try with a 67 318 factory a/c car???
Or have any other suggestions.
Im having a hard time believing that my perfectly working factory temp gauge has now **** the bed.
I also dont want aftermarket gauges in my cruiser. I just dont like the way they look hanging under my dash or wherever. They detract from my factory 40 plus year old interior. I feel like the car had 89k miles put on it with the stock gauges and I may put 500 a year on it so whats the point?
I will probably put a mechanical gauge on it and monitor that for a few drives then remove it down the road, however.
Until then any insights?
Thanks guys/gals
