Installation Instructions and Repair Stories

Steven from Beaverton, OR Friday, April 15, 2022

When I drained the coolant on my 2006 Morphous, it looked like it had never been changed so I decided to put a new thermostat in it. On the Morphous, which has a similar setup to the Majesty, there is a cross member right over the thermostat housing which makes it harder to access but by removing the temp sensor (at the mounting bracket) I was able to get to the bolts and lift the housing far enough to R&R the part. I didn't even have to remove the hoses. The hardest part is "burping" that cooling system and I had to do several fill-run-ride-burp sessions before the only thing coming from the bleed screw was liquid coolant. I extended the drain hose and dropped it in a container so I could watch the bubbles and catch the coolant rather than let it splash over the exhaust into a drain pan.

Difficulty level: Average
