Hey everyone,

I just noticed my grey water tank has what I estimate to be a pin sized hole in it. Last night it was dripping at a rate of one drop per 3 seconds, this morning it's not dripping but I still see a water drop around the hole. What's the best way to remedy this? I'm assuming there is some sort of patch I can use, but I'm curious what the best course of action would be.

Another issue when I drove it home I noticed a "whurring" sound when I had throttle in and above 55 MPH. It doesn't do it below 55, and even at speeds 55 and above if I let off the accelerator it goes away. It's not a super concerning noise necessarily, and I drove it over 20 hours with no problems. Just wondering if it's something I can fix, a sign of something to come, or maybe it's normal I don't know.

The AC also causes the belts to squeal when I turn it on at a stop, then goes away once I get some load on the engine. It's not a huge deal just kind of startles everyone near the coach when I'm at a gas station or parking lot. What's the procedure to properly tighten the belts? I'm assuming that's the issue since the belts are not even a year old.

Lastly, what size and type of oil filter do you all recommend?

Thanks in advance, hope you are all having a great weekend!

Tighten up your A/C belt, squak noise will go away.
You have a coachman if you have gray tank.
Get some Epoxy and fiber glass mat and glue around the leak. Be sur an
rough sand it well and drain the tank to keep it dry when gluing.
Call me for other concerns as I can see you need help.

Andrew,

I rarely would disagree with JimK, but here I have to.
That tank (I do not know for a fact) is probably polyethylene (PE)or polypropylene (PP) and it is real tough to make anything stick to either.
For the small hole in the gray tank, just get a stainless steel sheet metal screw and put it in the hole.

For filters, most of us use WIX 51258 <Look up 76 Toronado. Anything but Fram.
Oil - That has been a source of discussion (read fist fight) here for a while.
I like the 15-50 Mobil 1 (23$/5 qt at Walmart)
Rotela is also good, and many have used that with no issues.

It takes a pry bar of some kind to tighten the belts.

And if you don't want to put the screw in the hole. use Flextape! Sticks to virtually anything and is a real fast fix.

Hey, it's 40 year old plastic. Don't expect miracles. Tape is as good a fix
as anything. Screws, too. You already know the best method. Drag that
sucker out from under there, order a new one from applied gmc, and install
it.

Andrew,

Here's a repair I did on the black tank in Double Trouble back in 2009.

http://www.gmcmhphotos.com/photos/g6238-black-tank-repair.html

The doublers are held in place by the straps but there is no leakage at all eight years later.

In your case I would put a screw in as Matt suggested and then cover it with a patch glued on with 3M-5200 and if it works you're
done like a dinner.

If not then follow Jim's suggestion.

As far as the "whurring" sound goes, I would not venture a guess without actually riding in your GMC and listening to it.

As far as the belts go if they are not new I would replace them all see here:

For the oil filter see:

If you can get to the hole with the tank in the coach, there is slways plastic welding. I have had 2 black ranks and one plastic gas tan out of a Blazer plastic welded. It cost me $25.00 for each one of them. None of them have ever leaked again. The Blazer one had a gash in it about 4inches long from a piece of steel that my daughter ran over. Again it was a 5 minute job on the vehicle to fix it.

The screw idea also works. I put a screw in a big air compressor steel tank about 5 years ago. It has not leaked since then and it normally holds about 140 PSI.
