How many of us are there? Owners of Dodge based RV's?

Thanks Griff

The OEM is what I put on a few years back. The 'new' one didn't seem any firmer. No springs to be had. I'll try the 'suitable flex hose as it was much more ridged. Bought a cap too... will try flushing the system, swapping hoses, new cap, new coolant. Not quite up for trying the water pump just yet. Going with the easy stuff...

Without the part numbers... they would have had no clue what to hand me. lol. Kinda standard for me. Thanks again... I'll let everyone know how it goes...
