66 C code 289- I just detailed my engine compartment, installed a 160 degree thermostat and rebuilt the heater box with a new heater core installed. I pulled the radiator when I started the project. I also installed a fan shroud (stock metal).
I got the car back together earlier this evening, and refilled the radiator. I started the car and let it warm up. Once the car warmed up, the antifreeze overflowed, so I shut the car off and put the radiator cap on, wiped up the mess, and restarted the car. The temp gauge was almost on the hot mark, and after starting, it didn't cool down. Before I did this work, the car had a 190 degree thermostat, and if I had been running the car and shut it off, then started it again a minute or 2 later, the needle would be on the hot mark, then quickly lower to the normal running temp.
I'm kinda baffled as to why it is overheating now, especially now that I've done the mods to help it run cool. It has a 3 row radiator also. Any suggestions? Heater blows hot air, no hose leaks anywhere, inside or engine bay.
Another question, the carb spacer- does the hollowed out side face down, or up?
Last, the fan hits the shroud intermittently when I put the car in gear. from looking at the brackets that hold the shroud on, everything is adjusted as low as it can go. the bottom of the shroud has the least amount of clearance, and I tried pulling on it to see if I could gain any more space, but didn't have any luck.
Thanks for any help!
