2001 Chevrolet C/K Chassis Cab problems

What is wrong

Vehicle description: chassis cabs. On some of these vehicles, either or both of the two body pressure relief valves (prv) may not seal and could become inoperative during the life of the vehicle if the body installed on the vehicle does not protect the prv from road debris.

Risk

If a prv does not seal, exhaust fumes could enter into the passenger cab and could cause possible illness, unconsciousness, or death.

Remedy

Dealers will inspect the vehicle to ensure that the prvs are protected by the body of the vehicle. If the prvs are not protected by the body, the dealer will install new shielded prvs.
