Does Putter's first pic offer any help identifying where the seal is?

Just to be clear I access it from the inside of cab not from the cowl. I will check any other areas in the cowl area that access the cab on drivers side?

You remove it from inside tha cab. There is a clip under the cowl. You should be able to remove it with a pick. Installing the clip with the cowl on may prove to be a pain. I had my cowl off so it was a non-issue.

76bonanza · 11-01-2005, 02:43 PM

Well I am thinking of pulling the cowl on weekend and siliconing anything in there that loos like it might leak to the cab ya know what I mean.

Is it just the screws on top the bolton each side to under hood and the two behind each door? Anything more to removing it?

Thanks for your help

Correct. Well, ya gotta remove the wipers of course. If you have nice paint use a friend. While you are in there use white lithium grease for any moving contact patches on the wiper assy..

76bonanza · 11-01-2005, 08:19 PM

On removing those wiper blades is that a cover over the nut thing. Do I just pop it up with a pry bar or something?

texascowboy593 · 11-01-2005, 08:42 PM

On your wipers at the mounting point there is a small clip. if you use a flat blade scru driver as a "pry" bar it will push it outward and the wiper assembly should come off. Do this with care as not to damage your paint!!!

Rokay. I kinda lost track. I was talkin lube and he was talking sealers. Guess he was suggesting the sealer instead of the rubber gasket. Would not suggest it. The gasket is rather thick and if you do not use it I could see the geometry being a little out of kilter. Maybe it would not matter... I'm definately not a rocket scientist. Did not know that about RTV. Never occured to me to use it as a body sealer though.

There are different silicone sealers available. If you use one for automotive purposes, be sure that it says it is safe to use. When RTV types of silicone sealers are curing, they give off an ammonia type of odor. RTV in contact with steel, will cause it to rust, eventually.

Just be sure to read the label, so you will know.
