Re: 2003 Chevy Malibu coolant hose part number



I can't tell you for sure which is correct without seeing where they go, but by length you should be able to determine the proper hose.

Choice 1 is GM Part# 88907377 and it is about 13" in length.

Choice 2 is GM Part# 88907378 and it is about 17" long.

I strongly recommend not using the bulk hose in this application, as it has to make some sharp turns to avoid other components, and molded hoses as manufactured are the best choice in this case.

I have no issue reusing the spring clamps.

Is the hose that connects to the right side of the top picture choice #2?

I can't tell by that picture, unfortunately. That is why I would double-check by length. You should be able to visually see the difference I would think.

Yeah, you're right. Thanks for the help! I appreciate it!

I'm pretty sure it's 88907377. I found a picture of it at rockauto.
