I'm a new member with an issue and looking for guidance please.
I have a 2000 Honda Odyssey with 200K+ on the odometer. It is overheating on the road. When started for cold it will slowly read hot on the temp gauge, then pass normal operating temp and push to hot.
I have changed the themostat, thinking that was the issue. That has not fixed the issue. The top coolant hose is hot, the lower hose that goes to the thermostat is not. No heat in the van through the vents. When the lower hose is pumped agressively by hand I can make the temp gauge return to close to normal.
It is possible that there is a small head gasket leak, but not enough to see coolant pouring out and no milky residue in the oil either. The head gasket was confirmed by a dye test.
I was leaning towards the water pump being the issue, but wanted some experieced opinions before getting into a job of that size. I also read something about the temp sensor or a temp valve near the thermostat being a possible issue. Any thoughts or suggestions on how to further troubleshoot or repair are very appreciated.
