“””I had a Mazda that didn’t even have a thermostat..... just had to run the heat on high the whole way””””
Uhmmm. NO thermostat would make the engine run cooler.
Are you sure? I don’t think so. The thermostat runs to keep the engine from overheating, so running the heat brings the air away from the engine and under the hood.
According to freeengineinfo.com, Thermostat replacement is generally done if a car is overheating. The other possibility is that the car is no longer heating up correctly due to the thermostat sticking.
Meaning if the thermostat isn’t working (or isn’t there) the engine will overheat, not run cooler.
Not always correct. If the water flows too fast, it doesn't do the heat exchange and it runs hotter. If you're going to remove your thermostat, rip out its guts but keep the copper ring part to kind of restrict the flow. Learned this on a Vega.
Leave the thermostat out of your RX7 and life just got expensive.
You know it's bad news when the temp goes from normal to pegged in seconds that you've got problems. With a Vega, it's a blown head gasket.
