2001 2.5 MPV overheating
Installed a New thermostat and tested it with boiling water to open , new water pump, new 3 way molded radiator hose ( it had a cut in it) and still the coolant perculates. you can see the upper radiator hose jump or twitch. Heater gets hot but the temp gauge rises to dangerous overheating levels and then engine begins to miss a little bit. the upper radiator hose is very hot but the lower radiator is not as hot but very warm. If you idle awhile the temp returns to middle heat range. Is ther a way to purge the air from the coolant system? Could i have a radiator clogged up?

Just a shade tree mechanic but if the lower hose is not warm then you're not circulating coolant. Jumping and twitching in the upper hose would indicate pressure fluctuation and maybe air. I realize you tested the t-stat but maybe wire it open and reinstall to test circulation and prove the lower hose is not blocked.
Just my $.02.
I had the same MPV and my wife loved it. It had a ghost I couldn't remove. It misfired constantly. Interested to know what happens with yours.

I went ahead and opened the thermostat permanetly and i get heat at the interior vents, upper rad. hose very hot, lower rad. hose just warm. Engine ran 2 miles before temp gauge rose to danger zone, returned home and upper rad. hose was jumping and twitching. I believe the radiator is cloged and needs to be flushed clean. I'll attempt this tomorrow.
