2007 Avalanche Question


Recommended Posts

Posted

I know, I know...I still haven't made a formal announcement with pictures, etc. but I purchased a new 2007 Chevrolet Avalanche almost a month ago now. Work has been so hectic that I don't find the time to get on the forum anymore.

 

Anyway, I thought that the bed area of the Avalanche was supposed to be water tight. I'm not having any problems with the mid-gate, but the bed itself. I have the hard tonneau cover on (visible weather seal) and the tailgate up (visible weather seal around that as well) but I am still getting a lot of water in the bed area. I asked my salesman about it and he said that is why there are drains in the bed. NO...the drains are there for when you wash out the bed or for when you have the tonneau cover off and water gets in the bed. Why would Chevy put so much attention to the weather sealing if it is supposed to leak?

 

Just wondering if anyone else had the same problem or if mine is leaking and shouldn't (I think this is the case).

 

Oh yeah, I will formalize my purchase soon...I PROMISE!

My 2004 and 2006 Avalanche both had the same issue. Our two Escalade EXT, one a 2003 and the other a 2005 did not have any or at least nearly much water in the bed after a rain. It seemed to seal better than either Avalanche. But neither Avalanche had much water, just drops in the rear that came in at the seal between the last panel and the tailgate. Our current Avalanche - 2006 - also has a slight sag in the last panel - came that way from the dealer - about 1/2" drop in the middle of the panel where it meets the tailgate.

Very common problem. I've seen it on both the Avalanche and EXT. I know a guy who was so fed up with the leaking that he traded the Av for a crew cab shot bed and put a hard LEER tonneau cover on it. He still owns the truck and likes it a whole lot better then the Av. No more leaking.

OK, so is this something the dealer will attempt to fix? It is really driving me nuts that it leaks.

I don't think the Avalanches are supposed to be water tight. They are similar in design to the Honda Ridgelines which I worked on for 2 years at the Honda dealer. Even with the hard cover, they still got water into them. I'm sure if you looked closely at the corners, you will see drain holes.

Is their water in the middle of the bed area or just around the edge? I was told if it around the edge about 2 or 3 inches in where you see the edge of the mat that is for the water management system and you might see water their, but if you put your things to the inside of that they will not get wet.

Well that sucks... you'd think it'd be water tight. That would likley be a deal breaker for me if I were considering an Avalanche.

I have an '04 Avalanche Z71 and even parked outside in a downpour have had no serious water leakage problems. After a particularly heavy deluge, I did have some drops between the last panel and the tailgate seal. Usually this is the area that any leakage will occur. Make sure your upper drain areas and rubber seal channels are not clogged with leaves or any other debris as this could slow the water down and cause puddling and leaks. The AV's 3 piece cargo cover is not advertised to be "water proof", but in my case comes real close.

    • Ok that confirms the extra quart theme they are still going with which must mean they have noted some initial use more so then some engines and probably the bigger factor in all of this probably isn't the engine so much as its the insane distance or OLM that lulls a lot of the driving public into driving their new vehicle off the lot and not even doing one short interval oil change because the manufacturer doesn't say different and if the dealer follows that logic as well. Selling the rarely needing to be serviced concept seems to go over well with the public that wants to get away with as little as possible for dollars spent on the vehicles maintenance and I bet there are 3.0 engines just like other vehicles out there that never have their oil checked by the owner which goes back to why they probably felt the need to add that extra quart to avoid a costly theme.    Speaking of cutting filters open, it was probably over two years ago now that a youtuber who buys vehicles to do longer term reviews and pulls a fifth wheel through the mountains of Colorado on summer trips and that becomes part of the testing. Anyway he had a GM HD with the 6.6 gas and a Ford 250 with the 7.3 gas at the same time and of no surprise the Ford had more power etc but somewhere along the way in the few thousand miles he put on the truck, he changed the oil and was seeing glitter and cut open the filter and yeah, things were not looking spectacular. The truck about that time or soon after seemed down on power compared to what it had been and then threw some engine code, I expect the cam/lifters were failing and so he brought the truck back to the dealer and made some deal to get out of it as he knew it would sit for months waiting on a new engine as they were so backlogged at the time. He kept the GM for some time after that using it exclusively until he sold it after buying his next vehicle to do a review on. Definitely the filter can tell a story when things are starting to go sideways, but it would be a sickening feeling to cut it open and be faced with an ugly mess like that and be running a magnet through the pleats and the oil on the dirty side of the filter and see all the fines sticking to the magnet.    The dealer may have some ideas based on experience as to where that coolant smell is coming from, I would imagine if they can't find it but its smelling they would put dye in it to they could give it a run cycle and use the black light to see where it pops up, if its a hose connection, water pump, rad or even a head gasket etc. 
    • Good looking truck, suspensionmaxx looks like a solid option
    • Thanks for the info, im considering a leveling kit or 4" lift kit.
    • charm.li (website) has the vehicle-specific diagnostic procedure for that code, you can use to find what the cause of it is.
    • It’s at the point of amusement. I’m retired I have time. It’s fun seeing people try to convince me I’m using oil. I’m buying oil at the prescribed time. It gets drained and new goes in. Do I add in between, no. My oil doesn’t even get dirty in 5k miles. I don’t even see any drop on the stick. I check in the same place. All is well.
