Yesterday my sons and I started up the Hudsons after the winter storage. The 49 sedan started up OK no problems except for no brake lights. Does anybody know the number for a new stop light swith.

When we started the Brougham, the engine sounded loud upon checking it out we noticed a whole in the intake manifold. I have posted a picture of before and after. There used to be a plug or something that filled the whole and now its gone? Any ideas of how to replug this whole. It is 9/16" in diameter.

SL-134 is the napa/echlin number.

as a side note: are you by chance using silicone fluid? when using it, I was lucky to get a year out of a stoplight switch, (i had other problems as well due to the silicone fluid.) since changing to dot 4 i have had no switch problems.

should just be an expansion plug, i would be looking for clues as to whether it went in (no good could come from that), or hopefully out when it was lost.

Thanks for the advise on the manifold repair and I am going to look very closely to find out where that old plug went before replacing it.

I am using silicone fluid. I've used it in this car for almost 20 years with no problems. But I have heard about problems with silicone. I think my switch is just old.

It takes a 9/16" expansion or freeze plug found at any auto parts store. Clean out the hole, bottom seat the plug and with a punch and hammer, expand the plug by hitting it in the center (lightly).

Take note there are three of these plugs under the carb mount on a 2V manifold and 6 on the underside of a twin H intake they rot out so check them.

yup a freeze plug better for them to go than crack the motor or something along those lines

I agree with Nick S. I am using silicone fluid in my car and have lost a switch almost every year too. I got into the habit of keeping one in the car.
