Thanks! I saw that ,looks like its not metric. maybe pighead re- tapped with 1/2" ?
I'll give that a shot. The good news is, its easy access right now.Seems like you may have a restriction preventing hot water from flowing through the core.
I usually fix this by backflushing both directions using a garden hose until the core flows freely.
Lube rated for electric motors.waiting for the Monstaliner to be delivered (tomorrow) I decided to take a peek at the rear heater and fan.
I discovered :
1. The fan works !
2. the core doesn't leak!
Q; What type of oil or grease should I put on the fan spindle?
Thanks!
Have you flow tested the entire loop back to the rear heater?Question for y'all.
Heater switch works fine now. thanks @Pigeaten ! The valve at the block seems to turn all the way open but the hot water not making it to the rear heater core.
the valve seems to move freely and Ive opened it all the way. Could my thermostat be the issue? Seemed to be getting a bit warmer than normal sitting idling while I was tinkering with the fan/heater. Looking for the least messy way to diagnose... unhook the hose w/ a bucket and hit the key to see if the valve open?
ideas?

No, and how would I do that? I think the issue is the thermostat. I turned on the front heater when testing and It was also not warm, the temp gauge was a bit higher then normal as well , then suddenly the front and rear heater started to get warm indicating a sticky thermo. I did take the rear heater out and back flush it as suggested.Have you flow tested the entire loop back to the rear heater?
If the engine temp was warm but the heater would not warm, that would tell me there’s an issue with the coolant path from the water pump to the heater. If the engine was cool and would not warm to operating temp, then I would suspect the thermostat.the temp gauge was a bit higher then normal.

Correct. I have not yet ruled out the valve at the block but, the screw to open the valve moves freely. Maybe I shouldn't assume the valve opens fully then?If the engine temp was warm but the heater would not warm, that would tell me there’s an issue with the coolant path from the water pump to the heater. If the engine was cool and would not warm to operating temp, then I would suspect the thermostat.
