Roger E 0 Posted January 13 Share Posted January 13 My hood will not stay up---creeps down or or just shuts. How do I repair? Link to post Share on other sites
TAKerry 384 Posted January 13 Share Posted January 13 maybe new hood springs? Link to post Share on other sites
Pfeil 607 Posted January 13 Share Posted January 13 Hood springs for sure. In the mean time a hood stay. 1 Link to post Share on other sites
John348 1,410 Posted January 13 Share Posted January 13 I am pretty sure that they would be the same springs used by Chevrolet. The FIlling Station sells them and also has a tool you can either rent or purchase to do the job. 1 1 Link to post Share on other sites
Rusty_OToole 2,012 Posted January 13 Share Posted January 13 Some cars have different spots to hook the springs in, for adjustment. If your car does not have them you may have to buy new springs or make a prop. Link to post Share on other sites

You can't see them from that angle, they are along side the cowl behind the fender. The springs on the Chevy's are real "wimpy" and are known to get weak, I am 99.9% sure that they are the same Edited January 14 by John348 (see edit history) Link to post Share on other sites

Though both "A" bodies are the same body length from the cowl back, but Chevrolet has 115" wheelbase and Pontiac is 120". It's all in the front end for the straight eight. Hood and front fenders are longer. Longer means weight and leveraged weight multiplies. If fact Oldsmobile "A" body wheelbase is 1/2" shorter than Pontiac as well. 1 Link to post Share on other sites
Harold 138 Posted January 14 Share Posted January 14 IIRC, there were instructions for making a hood-spring stretcher in the '49-'54 Pontiac shop manual. Makes it easier and safer to remove and install the springs. 2 Link to post Share on other sites
bob staehle 43 Posted January 14 Share Posted January 14 I think Padgett was referring to the throttle linkage return spring Link to post Share on other sites
PhilAndrews 342 Posted January 14 Share Posted January 14 (edited) The springs on my Pontiac have seen better days- the hood stays up by itself but not particularly far- leaning over the fender to check the engine oil is about the limit of it for access. I've found people will lift the hood waaaaay up if they want to take a look, to the point the hood has taken the paint off the fenders where it's touched. If you like to park it up with the hood open, would recommend a prop, I modified a bolt and replaced one of the radiator shroud bolts with it. Nice and reversible, too. That way the prop can't go anywhere and I didn't have to drill a hole. Made a prop from a length of aluminum tube I bought from the hardware store, and that sits up in the notch in the strengthening brace. Polished up nice and was... easier than replacing the springs.

PhilAndrews 342 Posted January 14 Share Posted January 14 I added a torsional twist (rather than pull or oush linear) spring to my carb to take up the slack in the rods- which ended up not needed once I actually pulled my finger out and adjusted the linkage correctly. It's just not totally easy to get right with the Hydramatic and high mileage, worn out links. Link to post Share on other sites

That is amazing! You think that there are so many other hardware (window regulators, vent window assemblies, glass, and such) that they would be the same hood springs Link to post Share on other sites

PhilAndrews 342 Posted January 15 Share Posted January 15 (edited) As we're on the subject of springs: Top spring (by gas pedal linkage). Hooks to a groove on the lever arm, the other end to an anchor in the flywheel plate. Bottom spring- through a small hole in the lever arm, to a hole in the torus/flywheel lower cover. I found with the pins through the alignment setting holes the wear on the lower linkage would cause the lever to go over-center and make the pedal difficult to press down initially. Adjustment to keep the correct positioning of the TV arm in relation to the throttle position is still possible though. The lever arm should move quite far in the initial stages of gas pedal movement. That big top spring from the carburetor to the engine is not required if you adjust the linkage correctly.
