What do you guys think the average life of a thermostat would be? Maybe it all depends on the engine, cooling size etc? I've seen some cars go a long time with the same thermostat and others within 50k. The reason I bring this up is I'm putting the second thermostat in a Festiva in 75-80k. Don't know the actual mileage since I went through 3 Motoraid's till I gave up and went with Stant. My dad's other Festiva I replaced the thermostat last winter with the same mileage. On that one I went the OEM Motorcraft thermostat which is a dual stage, going to do the same with this one. Maybe that's why they didn't last as long? With the mileage he's putting on now probably never know.
Our Escape at 100k, parents Vibe at 95k, sisters Focus at 85k.. and I can think of a few others over 100k with the original thermostat. Some aftermarket thermostat may be okay for a select few but I'm starting to think OEM is best regardless. FYI alot of Mazda engines spec a dual-stage.. although not sure why. Never of heard with any other manufacturers.
