Heatin and cooling

Asked by May 13, 2019 at 03:55 PM about the 2002 Mercury Villager 4 Dr Estate Passenger Van

Question type: Maintenance & Repair

My Villager has rear heat and a/c. The top heater hose, the inlet hose mounted on the firewall has a plastic union as part of the hose were a temperature sensor is screwed in and is connected to the harness. The hose is a discontinued part and i can't find a replacement hose. My question is can i run a straight hose  without over heating the engine or damaging something being it's connecting to the computer.

1 Answer


As long as the sensor remains I place, you can. Fluid flow relates to hose diameter, and as long as the replacement hose is at least the same size, flow will be fine. Be careful not to damage the plastic union; and I mean really careful.
