Does anyone have DIY instructions for changing the 2 top left heater hoses and this part: 2028321115 - Heater Pipe; Assembly Through Left Side Firewall to Heater Core.

The hoses are very hard to reach. Thanks!

Hi Mr Darwin
Did you find the DIY ? I know this thead is 3 years old....but I do have to do the same job and it is like the part is impossible to reach

Any help ?
Thanks.

 

It is an easy fix. I don't know the technical terms, but let's call the broken piece 'the connector'. This piece mounts in the 'firewall' and connects the heater hose on each side. if you look at that part of the firewall, you will see how it is attached on each side. take those screws out and you can lift the firewal up a few inches, that allows you to replace the connector piece. hope this makes sense and works for you.
