Does anyone have a good place to buy radiator hoses for my Windsor?

HJLowell · 03-14-2019, 05:05 PM

NAPA Has always had what I needed.
I take in the old hoses and they match.
Big rig dealerships the same usually.

Someone posted this link a day or so ago where you can put in your coach and
it will show the hoses for your coach .
However when I put in an 04 Windsor it tells me the hoses are 2 1/4 inch
but I thought they were 2 inch , guess I'll have to measure my hoses .

I'll take those part numbers and my old hoses to NAPA in the morning. My hoses are 2 1/4". Surprised me too. I thought they were 2". I'll see what happens. I drained and flushed out all the green coolant today. Very time consuming! I'll be replacing it with Peak Final Charge "Oat" along with a new thermostat. A couple hoses are a little hard to get to, but shouldn't be to much trouble. My body doesn't contort in tight places as much as it could when I was younger.

Thanks for the input!

So did you find what you needed Wolfy ?
Thanks

I went to NAPA. Their computer wasn't much help. It only looks up according to year, make and model. So then they pulled out the books, leaving me to figure it out. They weren't very helpful. The main hoses are 2 1/4". It wasn't to hard to figure out that the big, lower radiator hose was going to be a problem for them. I checked with Auto zone too. They handle Dayco hoses, but couldn't get one long enough for the lower radiator hose.

After going home, I called Monaco. They told me that all the hoses on my rig were "Gates" brand. So they were able to give me the part numbers. As soon as I came home I jumped online looking without much luck at Gates corporate website. So I called them and talked to Bill. He was very helpful. He said that all the part numbers from Monaco were obsolete and not in their system anymore. He emailed me a download of all their hoses. I was able to figure it out from there, I hope. Gates doesn't sell to the public. I was able to search out the part numbers on google without any trouble. Bill said he receives many calls every week from shops looking for diesel pusher hoses.

Amazon had the main hoses needed and are now being shipped. One hose from the radiator upper hose to the reservoir tank is more heavy duty. Maybe because it's so long, 43". Gates recommended I call Motion Industries for that one. He said that hose is used on heavy equipment mostly. I'm guessing that Monaco had a reason for such a heavy duty hose. I'm not going to question their thinking and will replace with the same. I caught Motion Industries on Friday, just before closing. They will research it on Monday and call me back.

Removing the old hoses, most were easy to get to, with the exception of two that are very hard to reach, but do able. I flushed the system four times before I was satisfied. Very time consuming. I'm glad I'm doing it myself. I doubt that a shop would flush it out that well.

If it all works out, later in the week, I'll post the part numbers used.

Looking forward to your post with hose info.

RamiDav · 03-17-2019, 10:56 AM

The exact replacement hoses probably wont be available .
Finding a hose of the proper diameter but longer seems to be what most people use
A longer hose allows you to cut it to the need length .
Here is a thread from a few days ago that may help .

I spent the day installing every coolant hose on the Windsor. I'm sure glad it warmed up to 78 degrees today. It made the job a lot more comfortable. I bought all the hoses on Amazon. It took some time to figure out what part numbers to buy. To anyone wanting to do the same, here's the part numbers. It will save to a lot of researching time.

Two of the hoses "Gates #21418" had to be cut into three pieces each. Out of those two hoses, you end up with 4 small straight pieces and two 90 degree elbows. Just enough out of both, so don't cut any one piece to long or you won't have enough.

One "Gates #20401" is the large elbow needed on the front, lower radiator. No cutting needed for that one.

One "Gates # 24920" connects to the reservoir tank.

I bought the "thermostat is Cummins. Part#5284903"

The plain coolant filter, without additive is "Fleet guard # WF2077"

The job wasn't all that difficult, but it was very time consuming.

Thanks for the info. Getting ready to start on my Diplomat.

Thanks,

I used to use NAPA all the time and I'm an Amazon Prime user. Both have been good in the past. But currently I am finding that Rock Auto: www.rockauto.com has better pricing. This is where I have purchased all of my parts for resurrecting a 1992 Holiday Rambler Imperial 35'. There was one exception - I purchased front calipers from O'Reilly Auto Parts locally when my calipers started to not release.

When ordering parts at Rock Auto, they understand "P30" and most of the time if there is a difference in part choices based on application of the P30 chassis, they will designate "for MH" (motorhome).

AdmiralRV,

Please note that my Windsor is a side radiator and your hoses will be different for a diplomat rear radiator application. I still believe I would look at Gates hoses first. You will have to measure all your hoses. When looking at hose charts, the length of the hoses are a centerline measurement, if that helps you any.

Good luck
