🌡️ 13779 OE Type Thermostat by Stant - Stainless Steel Review

I have a 2004 F-250 4x4 with a 6.8 liter V10 engine. I replaced this thermostat when I did the water pump, radiator and hoses. It worked great! Looked exactly like the OEM part I removed.

Stuck Motorcraft thermostat replaced with this stant. My 03 Grand Marquis is safe in the sense that it is no longer in danger of causing critical engine failure by overheating. I like it better than the stock Motorcraft thermostat because it has a factory pre-drilled air outlet. Nice gesture.

My '05 F150 has just covered 100,000 miles and is taking a little longer than usual to warm up. I've always had good luck with Stant products and am replacing my thermostat as a preventative measure. I check my thermostat once a year when I change my coolant to make sure it's still in good condition. Stants are as reliable as factory engine thermostats and I expect them to last 100,000 miles.
