Changing radiator hoses
I have a 2004 DP with a rear radiator. I am getting ready to change the coolant and figured I would change the radiator houses.

How do I get to the upper hose?

2004 Rexhall 40'
Workhorse R20
Cummins 8.9 ISL 400

Limited number of members with coaches built on the Workhorse R chassis .
Rexhall might have it's own access issues .
Have you looked through all the access panels ?

First thing would be to source the parts , you'd hate to damage one during removal and find out there isn't a replacement available .:blink:

I will have to look for access panels. Under the bed has one but seems way too far away from the upper hose.

I will check on house availability.

Use t-bolt clamps for rad hose. Had worm type clamp break(rusted s/s clamp) on upper rad hose.
