I have a 2001 Chevy Camaro with 85,000 miles. Engine Size is the 3.8L.
Question: I am looking to replace the heater hoses. These hose's are made as one assembly with aluminum pipes connecting them together with a crimped coupler. Also two of the hose which connect to the belt tensioner have a unique end connector.

Can I just buy replacement hoses and connect them to the existing pipes or do I need to replace the complete heater hose and pipe assembly? Also, this problem has to do with the serpentine belt coming off the pulleys. The issue only occurs at the time when its raining or wet out be it a light rain or heavy down pour the belt will come off. Any other time when it is dry out I do not have any concerns. What could be the possible problems with the belt?

Answer:
Your best bet is to visit your local GM dealer and purchase original quality replacement parts. You would get the proper hoses there, and the fittings you mention are 'quick disconnect' fittings which would come with the hoses if you purchased them completely. I wouldn't recommend piecing the hoses together with just general heater hose, as the factory units are pre-formed. You'd have a hard time getting the bends correct without that. Also be sure to purge air out the cooling system when the repairs are finished. If you do not get the air pockets out then you ill run into a problem of no heat from the vents or even an overheating engine.

As for the serpentine belt coming off the engine when it's wet, you either have the wrong belt on the car, or you have a bad tensioner, or broken pulley. There may be a pulley that is not aligned properly with the other. Either because the bearing is bad and it it loose, or the component is loose. There is a laser tools that can check that they are all straight. Usually under no circumstances does a belt normally come off- dry or wet.

Chevy Camaro A/C Hot Drivers Side Vents

Question: I have a 2011 Chevy Camaro and the A/C blows cold on the passenger side and hot on the driver side. It's not a dual control system. I took it into a mechanic and he evacuated the system and replaced the Freon to normal levels but I still have the same issue. Any idea why it would be doing this? I'm trying to avoid any expensive repairs. I also should mention that before I took it into a mechanic I tried adding R134 myself using the A/C Pro brand. Could that have caused damage to the compressor?

Answer:
First off, no, using that kit from the parts store would not have caused any damage. If the temperature coming from the drivers side vents cannot be changed at all when changing the temperature controls, then it sounds like the door for that side is broken. Even though it is not a dual zone system, there is still a temp blend door that controls air temperature coming out of the vents. Electrical testing of the motor would be needed to confirm that, but it is a common problem on Chevy cars and trucks.
