Griff & Leeann... calling on your expertise.
So starting to run out of things to try and check.
Overheating... running hot.
In 2013, the Waterpump went out and was replaced. Around 2009 or so the engine was rebuilt. Maybe 10-12,000 miles at most with the rebuilt motor. Last fall I did replace the thermostat, Found out it had the wrong one installed. I did track down and install a 180 degree skirted thermostat. I'm wondering if maybe the 440-3 engine that is in the RV requires a special part for the water pump as it did with the thermostat.
About the only thing I have found online for a resolution to my problem was someone who used some acid based flush that solved the issue.
It idles OK, seems OK until I get up to high way speed.. starting about 50mph, the temp climbs.... from about 3/4 5/6 gauge upward.
I want to travel a few places yet this year but am having problems getting out of town. Any ideas or questions for me?
Second item... Speedo cable. It came with some cruise control on it. IT worked back in 2007, doubt it works any longer. Don't think I need to try and keep it in line... so single cable that goes to the tranny would be fine. Unless you may know what to get for the cruise control module.
That's a couple starter questions...
