Found why my truck stinks....leak

I would guess it is coming in along the side of the gasket next to the "A" pillar. The three Fj60 that I have removed windshields from have all had water in them from this area even though it has not rained in 6 months.

I may also be coming in through the heater ducts from the fresh air opening in the center of the front cowl. There is a drain and if they get plugged with leaves or pine needles it can end up in your cab.
 
Here is a picture of the drain. The downward elbow and the rubber pipe have been removed. Theses are located behind the fender near the front door.

I get the same thing when I wash mine. Pissed too when I found it. I noticed that the a/c drain tube was also pointing up, turned it downward and put a zip tie to hold it better and help seal it off better.
Gonna check now...I do get a dripping from upper passenger side a arm near sun visor area, when it rains, and i am on the road.

If it's the passenger floorboard, make sure it's not antifreeze. That would indicate a heater core...

So I'm trouble shooting the wet floorboard syndrome too. I know one cause is the weatherstripping, so I'll take care of that. But re: D'Animal's post, is there a way to check/clear that drain tube without removing the quarter panel?
 
nope. The fender comes off pretty easily though. 12 mm bolts all the way around
 
If you have a roof rack then I would suspect the rain gutters. The caulking gets brittle and breaks. Peel out the old and put in some new 3M rain gutter sealant (all around body caulk). It fixed mine.

Roof rack is newly installed. Would that torque the rain gutters and open them up a crack?
 
BINGO! I bet its the Gutters.

I discovered the solution to my leak was the rubber gasket between the cowling and the rear of the hood.

This rubber piece keeps water from dripping into the engine compartment and down the firewall. If water drips down the firewall, it will find its way to the rubber grommets in the firewall. If any grommets have holes, are missing or have aftermarket wires going through them and not properly sealed, water will leak through onto the floor boards and soak the carpet.

Before tearing apart the truck, check the rear hood seal first and your firewall grommets.


I almost tore apart my car looking for the water leak after every rain. The rear hood seal, who would have thought!

You do not have to take the fender off.

You can blow into the air vent screen between the wipers. The only thing in there is your wiper motor and linckage. If your compressor does not have enough air just use a leaf blower.

You can also open you door and try to still the small end of a wet dry vac onto the end of the drain.

my question too...
 
Leaking hood/cowling weatherstriping

Dudes - This issue started for me after a major power plant over-hall and I was worried that it was a new unsealed hole in the firewall. We are talking LOTSA water :eek::doh:. Not just a damp carpet. So I knew it had to be somewhere that water was concentrated/funneled.

While exploring for possible leak locations I found that two of the plugs (Toyota calls them clips) that hold the welting down to the cowling were missing/broken. Talking about 169, 010 & 910 on this diagram.

Toyota part#'s are
55791 - Weatherstrip
55791B - Clip
90563-06003 - Clip

For the clips I found something very close at the hardware store and have installed them. Rainy here this weekend so will be a good time to see if that's the problem.

Will report back.
