Avalanche Tonneau Cover Leaking (Causes & Solutions)

It is always disheartening after spending much money on getting an OEM truck bed cover and you notice traces of water in the truck bed. The knowledge of the causes of the problem could help you if you are in such a situation. Below are some of the causes and things you can do to resolve the issue.

Heavy rain

It is an irony that the cover you have spent money on to protect the truck bed from rain also leaks water during heavy rainfall. Just like other types of cover, the Avalanche tonneau cover could also leak water when there is a heavy downpour. Though it might not be as severe as it would have been if the cover is not OEM.

Most of the time, when the Avalanche tonneau cover leaks water during a heavy downpour, it could be due to the position of the panels or when there is an issue with the gasket. Below are some of the things you can do to resolve the issue.

Adjust the panels

After some period of using the Avalanche tonneau cover, likely, the panels are no longer in the right position. When you notice water leakage in the truck bed, you should gently adjust all the panels.

Replace the seals

Another reason why the Avalanche tonneau cover could leak water into the truck bed when it rains is when the seals are no longer effective or missing. Once you notice water in the truck bed after a heavy downpour, you should inspect the cover for missing seals. If there is any, you can contact Chevy for a replacement kit or you get a new one in your vicinity.

Replace the gasket

One of the functions of the rubber silicone gasket on the Avalanche tonneau cover is to prevent the entry of water into the truck bed. In a situation where the cover begins to leak water, you should replace the rubber gasket.

Pressure washer

One of the ways you can care for the Avalanche tonneau cover is to wash it regularly. While washing the Avalanche tonneau cover with the use of a pressure washer, the cover will likely leak water into the truck bed. This could be due to the pressure coming from the machine. Below are the things you can do to resolve the problem.

Dry the truck bed

Once you are through with the cleaning process, you should inspect the truck bed. Pick your wet valuables, dry them, and then clean the truck bed also. You need to do this to protect the cover from being damaged by water.

Seek help

There are instances where you might not be able to resolve the issue yourself. You need the help of professionals or the manufacturer to resolve the issue. Once you experience leakage during pressure washing or regular wash, you should contact the manufacturer or any professional in your vicinity.

Blocked water drain

The Avalanche tonneau cover is designed to drain water with ease. The water draining system does not allow water to stay on the cover for a longer duration. However, the system could be blocked after a while due to the presence of dirt residual on the cover.

When the system is blocked, there will likely be a pool of water on the cover. This implies that the cover could leak from the sides and the tailgate. The following are some tips on how you can resolve the issue.

Dry the cover

If the draining system of the Avalanche tonneau cover is blocked, there is a high chance that the cover would retain water when it rains or when you wash the cover.

This will then cause leakage if you leave it there for a longer duration. You can use a dry towel to get rid of the water on the cover. You should also dry the cover before you open the cover to prevent water leakage.

Clear the blockage

Once you notice that the Avalanche tonneau cover does not drain water the way it should, you should inspect the cover for potential blockage of the draining system. If there is any, you should carefully attempt to clear it.
