Hi all.
I had an interesting experience this weekend. I went on a 150 mile trip and kept up with traffic at 80 MPH. On one long uphill stretch the car started to warm up (3/4 on the gauge) and it never did that before. I pulled over and saw some coolant released from the overflow, so I just raised the hood and let it sit for 20 minutes. I then started it up and the gauge had gone to half, so I re-entered the freeway and completed my journey with no repeat of the heating. When I bought the car it still had the original radiator in it, so I had it rodded and boiled, but not recored. I also replaced the radiator hoses, but could not find a lower one with a spring in it (like they all used to have when new). Now i think I know why the car ran hot (first time in the 3 years I've owned it; high speed and a vacuum in the lower hose that was not offset by a spring in the hose to keep it open.
So, which manufacturer makes the correct lower hose for our cars that has a spring inside it?
Thanks
Norm

Thanks. Everything is fine in the cooling system. I'm positive this (cooing hose collapse) is what happened-I was going up a 2 mile grade at 85 mph in 85 degree weather. Any idea who still makes hoses with springs, or am I going to have to scout junkyards to find one?
Regards
Norm
Today I got confirmation of my radiator hose spring theory-took the same 150 mile trip at high speeds (75-80) as I took when the engine ran too warm last week, only this time with the spring inserted in to the lower radiator hose. The result: the temp needle stayed at one needle width beyond the first quarter mark (like I remember they did when they were new). Case closed.
Where did you find the spring?
That's easy: I went to the name I trust for Cadillac parts over all others: the "JasonZone"

Could someone post front and back photos of the 1963 right-hand kick panel with A/C?
My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.
Many thanks,

Hey guys,
I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great! In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…
