That's why I just went with good ol green. Thanks for the suggestion, that's some pricey stuff!

Well, having repair mans remorse after filling with standard green. I dumped my old coolant for recycling, and I thought for sure it was green...a little brown too. But in the light if the recycling shop I could see it had a pink tint to it while poring it put. Now I wondering if I'm ok or if I need to dump it all, flush and fill with Fleet Charge or similar. Thinking there were 2 coolants blended together before I changed it, and, how real are the internet stories of mixing the two types. The only leftovers would have been in the heater core and lines, maybe around 2 gallons. I need to think on this one.

Got the job finished today. What an absolute mess of a job....so glad I degreased and washed the motor as I was still a fifty pig when I was done. The hoses mentioned above worked pretty much perfectly but it sucks cutting and wasting so much. The green fleetrunner belt I bought could have been another 1/2 longer, but I got it on there. I did add 1/4 turn valves for the heater hoses and also had to replace the exhaust clamp hanger mount they made for the hard pipe. I ended up putting back in about 8 gallons of coolant and distilled water, and I hope to run it a bit this week local to check for leaks. I think I spotted one more 5/8 elbow and a 5/8 hose section I missed on the back of the engine. I guess I'll just carry some spares. Good luck to the next guy...and here's to another 17 years!

Can't pass up a Bucees! No problem with either of the FL ones on 95 with the Neptune and my Ram in tow.

Straight from cummins I do think new. Bill was 6k and glad it wasn't mine!

I'd have to look at it to scope it out. I do know the turbo was replaced due to vgt and egr issues not too long ago.

I had a major jackpot while refinishing the cooling tubes on the Neptune tonight. I feel they are still in good enough shape to put some more miles on, so after wire wheel and roloc disc cleanup, I put on 2 coats each of primer and paint. But, while I was wire wheeling, I noticed some numbers stamped on the ends, and after some super internet sleuthing, I present to the 5.9 ISB roadmaster crowd the following: Upper Coolant Tube Part number: 01808094 Lower Coolant Tube Part Number 01807611 Currently both available in STAINLESS for about $200 bucks each..with 2 day manufacturing from PA! https://bhtubes.com/coolant-tube-2-x-2-1-4-diameter-replaces-01808994 https://bhtubes.com/coolant-tube-2-1-4-diameter-replaces-01807611 Now, the upper part number is 1 digit off on the upper, but the pics they show are identical to mine. I don't have any idea why this manufacturer was so hard to find, but it's awesome that these are out there with the aging fleet we are running. So go check out BH tubes, no matter what rig you have. Some pics of tonight's work for reference....

I found its a 16 pound so that's what I picked up. Hope to start reassembly tomorrow.

Yes that's the petcock I was referring to. It is for the cooling...its an air bleed and I'd connected to the bypass circuits. It's fed by 3/8" heater hose with Parker style barb fittings. All of these are pressure and adds to the bill when a complete hose job is in process.

While I'm at at it, anyone with a Cayman / Neptune know the rad cap pressure? No markings on the one I took off and it needs replaced. Thanks!

Ok, got all of the hoses off and got to finally look at the coolant tubes. I think they looked worse than they really are. Surprisingly clean on the inside for what looked like original coolant. I plan on dressing them then primer and paint. The coolant hose from the tank to block turns out to be 37 inches of 1 1/4 heater hose with NAPA markings so I hope to find it. As far as the little hoses, the oil filter had to come off and the little 90s were hard to get to. The one behind the filter is actually silicone, which I was glad to see because it takes some heat where it is. Had to stop for the night, and i need to get some supplies at NAPA before putting it all back together.

Got after it today. Have more work and hoses than I thought. There is a tiny 90 elbow up against the motor that is cracked pretty bad and there are some hoses behind the oil filter I am going ti tackle as well. Getting to be a big job!

Thanks, I figured it out once I looked again. That means I have more hoses to change!

After really getting deep in there....it looks like a fuel bleed?? Definitely connected to engine tubing.

Any idea what this is on my Neptune? Upper drain for something. Can't tell if it's water or coolant that comes out. Haven't dug too deep but seems too high up for anything coolant.

Awesome Carey! In fact, thats what I was coming up with through my searches! It is really expensive for what it is. Other thought was to use a corrugated style hose that be easily had since not much water is actually passing through there.

Thank you. Check out the post I just made on the main page about hose lookup on the Dayco web site.

Would have been nice to find this earlier! Not sure how accurate it it's but seems legit based on my 06 Neptune hoses. Check it out...... Use the application tab, heavy duty and put in your coach! https://na.daycoaftermarket.com/en/applications/automotive/#page=application

Picked up my thermostat from Cummins. 65 bucks....I guess cheap insurance. I can't locate the correct type of hose for the overflow tank to block so I guess I'll tear into it and work it out then. Last thing before I start was to decrease and pressure wash what I can to try and stay somewhat clean. Maybe this weekend?

That is a furnace fan cut in/ out switch. I know, my furnace at home is a 1970! I replaced it last year. It sits in the flame and turns on the fan once the exchanger is warmed up, then it is slow to cool so the fan keeps running until it resets. All mechanical like a thermostat. Honeywell L4064B2236 Combination Fan and Limit Furnace Control https://a.co/d/7nVL2QI Looks like they used it as a fire warning. Probably makes a light or alarm go off somewhere....interesting idea!

Had a chance to adjust my entry door today. My door seems to be a bushing model, with no bushing present. I was looking around for something to make one out of and gldug into the rv toolbar and came up with something I think will work for a while. I had some 3/8 tubing and a flare kit from a blown tire in a 5th wheel a while ago that took out my propane line. I made a little flare and cut off. Fit in there pretty good! Time will tell.

Hey Carey, was under the Neptune today and realized there is about a 6 foot section of 1.5 inch hose that runs from the bottom of the pressure tank to the block. Did you deal with that hose? Got under the front today near the heater core. I located a transition from heater hose to what looks like PEX! Pretty sure it is....and the connection is right on top of a crossmember for the stairwell.

The bedroom door now opens in, not out into the bathroom to compete with the WC door that opens out and the shower door that opens into the same space! When 2 people try to utilize this floor plan in the stock form it's a train wreck. I don't know how anyone lived with it the other way!

As title says, one trip was all I could take with this crazy configuration! Had time tonight to swap it around and it seems better already! Would love to meet the floor plan designer....must have been a wine dinner sketch. Don't mind the blinds....already on the list! I know I saw someone else post this but couldn't find it.

Wonder if my neptune should have these? I do get windshield wobble on some roads.
