Hi guys,

My 60's driver's floor get wet when it rains and I can't figure out where it's coming from. Originally I thought it was the lower corner of the windshield so I put some silicone there but the floor still gets wet. It's to cold to run a hose and do a thorough check.

Are there any common places where the 60s are known to leak?

Thanks,
Carl
 
The WS corner is a prime suspect, but may require removing/replacing the glass and a good glass shop that follows the FSM to get it to seal correctly. Search for various threads on this. I had a competent glass guy recaulk my corner, but it still leaks, so I'm awaiting a full glass reinstall when the time comes.

Other leak spots include the A pillar and roof rain gutter areas. Check all these areas for rust, bad caulking, etc.
 
Thanks Steve!

Make sure the drains in the doors are clear as well as the path runoff takes in the door jamb where the hinges are. If the door seals are bad, runoff will leak past... That was the source of my wet driver's floor even after a new windshield install.
 
Mine was leaking from the rain gutters. Water leaked down the interior A-pillar to the floor. Check the area around the hand grips, if wet there it's likely the gutters.
 
Great info guys! Thanks!
 
I solved the source of a leak by pointing the garden hose at various points on the body until I got a flow of water. You have to start low and work up.
 
That was my test plan but I have to wait until things thaw out around here first.

Does anyone have the FSM pages for the windshield? I'm having the same leak.

Doesn't hurt to seal up the rain gutters either way since they're so prone to leaking/rusting.
 
I would also love a copy of those pages.

Thanks,
Carl

Did you have rot/rust in the gutter? Mind posting a pic of what area you sealed and what you used to seal it?

sorry car is in storage. I had no rot or rust was repainted 4 years ago and the seam sealer had cracked. just used an epoxy seam sealer that was clear to run a bead down it.
 
I had a similar situation that I finally got fixed after 4 months of pulling my hair out. Long story short...I noticed water on the driver and passenger side floor after it rained...the truck has been in a garage for the past ten years so the PO probably never noticed. Had the windshield gasket replaced...no dice. Then I came across an article in the TLCA toyota trails publication.

Toyota Trails - January/February 2017 Issue

This is probably the culprit in the majority of the these pre 1988 trucks. The body seam sealer behind the front fenders that runs down right below the upper cowel are was put on by hand and not well back in the day...(I imagine a tired Japanese guy on a Monday morning that had too much Saki the night before)...and anything that is still there after 30 years is gone...anyways...the fenders have to come off and seams need to be resealed as laid out in the above article. I tracked the author down who lives in British Columbia and picked his brain on this subject (he does amazing restoration work btw) On his advice I found a local body shop, printed the article/pictures off for them and they fixed it perfectly! My truck is now bone dry in the hardest of downpours. I know this thread is a little old but wanted to share my success story.

a little late, but here it is.

I second the recommendation to find a glass installer that will follow the FSM to the letter. I just went round and round with a local cruiser shop here that dismissed the FSM and said they never came that way from the factory. Anyways it leaked after they replaced it. They weren't able to get it to stop leaking after a second go at trying to seal it up. I found another shop and spent another 300$ to have it done right....at least I don't have leaks now :beer:

BTW, there are separate FSM instructions for Canada trucks. It might not be a bad idea to follow those if you live in a cold/damp environment. It involves prepping the gasket. Both USA and Canada instructions still call for adhesive to both lips of gasket...gasket to glass and gasket to body.
 
Don't waste your time or your money going to a shop to get the windshield put in or the adhesive on.
If you have another person to help, you can get the windshield installed in like 20-30 mins, even less if you have a third person. Then after the window is in, another 10 mins to put the adhesive on the gasket to the glass and gasket to the body. The most time consuming part is masking taping it off like the FSM says.
My husband and I are basically clueless, and we were able to do it just fine. Watched a couple YouTube videos on the string install method, and a couple of the window suction cups (but they really weren't needed). Seriously, I really feel anyone can do this. It looks intimidating, but definitely can be done.

I'm not really taller then my 60 in the pic above, I'm on a step stool, which helps with the install if you are short like me. But I was feeling pretty good after getting the windshield in, definitely a confidence booster!
 
@ Aloha Jenn....nice work! Now I wish I would have done it myself!:doh: I live in Portland, OR and literally no glass shop in town would guarantee their work to be leak free and the local cruiser shop was unsuccessful twice. I just happened to find an old school guy at a body shop who was fearless and always glues the way the FSM recommends....working out so far. How long have you had the glass in? No leaks??
 
I had a leak that, as it turns out, was from rain going down the firewall and following PO installed wiring through a ripped firewall grommet below the brake booster. The water followed this wire to just behind the dash and dripped on the floor mat. I re-sealed the firewall grommet and it's been bone dry ever since.
