Looks like you have taken a sensible approach. Please keep us posted on your progress

I would have tested the Big Boy to determine if it’s bad prior to purchasing one. Also, they are very easy to rebuild/repair. Usually the dielectric grease inside dries out and gums up it’s action rebuild instructions https://www.monacoers.org/applications/core/interface/file/attachment.php?id=2366

Seems like you need a new clock Spring.

As David mentioned above, I would try unplugging the DRL module.

So I swapped the lines on my valve and the fan has calmed down. Whew. That was easy......for a change. Thanks to all who replied so quickly and offered help and advice. Really appreciate everyone on here!

Thanks Frank. Since it is the same valve That was in the old radiator I don’t suspect that it will need any adjustment but it’s certainly Gond to know Kevin I would like to see the info that you have on the valve. It’s always good to learn how something works.

Ok. I hope so. Hoping not to spend another $350+ on a new valve. Thanks guys. Good to hear that you have the same issue Kevin. I will swap them in the morning and let you know how I make out. So glad to have the radiator and exhaust project behind me. I was a big one for sure

I completed a radiator replacement recently and started up the Coach yesterday. It runs fine and everything came up to temp fine. The radiator fan runs at full speed constantly though. I know this is a sign of a bad wax valve but I was wondering if there is a specific flow direction for the valve. When I replaced the lines with new I lost my marking to tell me which line went where on the valve. Didn’t see any flow direction marked on the valve. I plan on reversing the lines to see if it solves the issue but I was wondering if anyone knew if it makes a difference. thanks

Blowing out the lines and not adding antifreeze is not recommended because there is the possibility of some water remaining in the loops and settling at the bottom. This could get real expense real quick.

I am getting the same error message despite resizing and saving multiple times. Looks like it saved it though

The radiator install is complete. Just waiting on one coolant hose that it supposed to arrive tomorrow. Coach is back on the ground. Wanted to get it down before we escape to Fl for Oct. the startup will have to wait until Nov. how it’s still warm enough when we are back to give the coach a good bath. It’s a mess from all of the grinding and cleaning. So relieved to have these projects behind me. It was a significant endeavor for sure.

Thank you Vito!!

The radiator Arrived late yesterday. RSH did a great job. High quality build! Spent the day today assembling the unit and got it back in place. Just have to connect all of the hoses tomorrow and fill the fluids. Sure will be glad to get this one done. Sorry, don’t know why the image is loading upside down

My manual states that Dextron III is to be used for the hydraulic system. Does anyone know if using Dextron 4 is permissible?

There pricing is very close to where I ordered but I found the site a bit sinful to navigate. Radiator arrived today. Assemble starts tomorrow.

Yes. M-147. USA Truck Pipe had the lowest price

So I finished the fabrication of the new exhaust last night. Overall it went well. Had to MIG weld instead of my usual TIG preference due to the aluminized components. Came out good though. In it goes today and hopefully the new radiator shows up tomorrow. It was in NY as of this AM

Oh. I didn’t realize it was a split tank.

I would replace it. If it has a pin hole then there are other areas that are very thin. I would buy a used one either because you could be down the same path before long. The tank doesn’t have to be the exact size and make. What about the possibility of using a propane cylinder? You can get new ones fairly cheap and have a local shop weld up brackets for you.

It would be hard to dig a trench in concrete 😂. I will never depend on the suspension. I made blocks some time ago to put between the frame rails once the suspension is at its highest point to secure it. I will add more blocking under the tires first and then raise the suspension if needed when the assembly is ready to be installed. Thanks for the tip and concern!

All of my new exhaust components have arrived so the fabrication of that begins. Meanwhile, the new radiator has been shipped and is scheduled to arrive on Tuesday. Weight of the shipment is 352lbs. So that confirms that the radiator is somewhere around 300lbs. Will have to raise the Coach up an additional 12” or so. To get the assembly in without tilting it. I’ve make up a hose to connect to the front air line to raise the suspension when I’m ready. I’ll post a few pics in the next few days

Thanks!!! There was a cap on it but I must have bumped it off

Fan assembly taken apart, cleaned, POR-15 and Rustoleum and reassembled. Need to get a couple new fittings but besides that ready for install. Radiator still not shipped yet. They have been loosing production time due to the Oregon wildfires. Exhaust components arrive tomorrow so that fabrication can begin.

I know that I bought the Cyclone branded one and paid Around $25 or so.

I had a similar issue at time when headed down the road. First I confirmed that my vent pipe was attached properly and then I ran a hose down it to be sure it was not blocked. With both of those things confirmed I decided to try the “Cyclone” roof vent and it completely solved my problem. Have not had even the slightest smell since.
