My 1966 mustang has a water leakage problem, most of it appears to be coming from the cowel vents. I am ordering a cowel vent repair kit, any suggestions on the easiest way to repair these leaks? it seems like a lousy place to get at.

 

Hope one of our teckies can help and good luck

 

Wish i could help,but i am not familiar with the design of the classic mustangs besides with the visuals.Good luck.

 

well thats is a major job, have done mine in the 65 mustang, have to remove the fenders and hood, windshield, then drill out about 200 spot welds that hold the top of the cowel vent on, put in the patch panels in , and weld it all back together.. have pics of mine

 

, it may be easier to keep the stang out of the rain and be careful with the
hose...sorry for your luck!

 

the other way is take the dash apart, and remove all the duct work, heater box guage cluster etc, and fiberglass the under side of the cowel, around the vent tubes,, but it would still be an idea to remove the front fenders to clear the drain holes at each end of the cowel.. I repaired both ends of my cowel, then fiber glassed that whole section around the vent tubes so now its completly sealed, and no one will ever see it once the thop cover is welded back on

Wow .... that's a lotta work for a leak.

 

Thanks for the info! It is a hell of a lot more work than I am able to put into it and I couldn't do it properly myself so it would cost a bloody fortune. My car isn't a show car, just something I enjoy driving around in the summer so I fixed it real cheap. Got a can of urethane foam and sprayed all the cracks and joints under the dash and around the cowls. Not a professional job but it stopped the leaks.

 

Without doing what firstday65 is suggesting the old girl will leak for sure. It was the most major cause of the floor pans rotting out. Our 66 coupe was repaired properly and it was a very large undertaking. The drip pans in our car are stainless now. We are in the process of re cauling the seams with factory caulking. Floor pans were replaced as well as firewall. Massive undertaking but well worth the effort as they are a dissappearing breed and with the new body design being a shadow of "old school" these old girls are increasing in value quickly. Time and patience does pay of even if it is personal satisfaction on a job well done. Just my 2 pennys...and happy motoring!
