rustykramermetalfab Posted June 16, 2023 Share Posted June 16, 2023 I am looking to change coolant and want to replace all the hoses I can. Looking and found some dayco part numbers supposedly for the 2006 Dynasty daycoaftermarket.com but no diameters of the hose listed. If there is a listing of the proper part numbers on Monacoer's I have not located it. Can anyone advise ID of the hoses? It would appear measuring that the OD is somewhere around 2.750 I have not pulled any just not ready to do that yet. I would like to have everything ready once I start this project I just don't want to have a batch of hoses that are all 1/4" wrong. Thanks for any help guys.

Guest Ray Davis Posted June 17, 2023 Share Posted June 17, 2023 Many have taken their hoses to NAPA or some other store and found a hose that is longer but has a portion that matches the old hose and cut that part out. This was a topic often yrs ago on the old Yahoo forum. Link to comment Share on other sites More sharing options...

You have to use the Heavy Duty tab and not the Automotive tab. I looked at the ID of the hose and then tried to measure best I could on the coach. Hope this helps.

georgecederholm Posted June 17, 2023 Share Posted June 17, 2023 On our 2005 Exec, I was able to determine the hose ID values by measuring the actual pipes, then trying to verify by subtracting hose wall thickness (times 2) from the hose OD. I did find that the pipes Monaco used were slightly smaller than the inlet/outlet fittings in the engine (2.25 vs 2.375, I think) so a couple of the hoses had different ID values on each end so check both. I also found a Gates site that has a lot of info on sizes and shapes. I found the best Gates fit I could guesstimate and with that number, I could cross reference to most anything. I ended up getting the hoses from Amazon and Walmart.com. https://assets.gates.com/content/dam/gates/home/knowledge-center/resource-library/catalogs/gates-molded-coolant-hose-id-guide_web.pdf#page112 Link to comment Share on other sites More sharing options...

rustykramermetalfab Posted July 3, 2023 Author Share Posted July 3, 2023 I am getting ready to change my coolant out to Peak final charge. Not sure exactly the type Global or not? I have been searching but not really sure based on what I see on the web. 2006 Cummins ISL 400. Plan to flush with Distilled water in between. I am going to change out all hoses. thanks Link to comment Share on other sites More sharing options...
