Vehicle Production Information
Owners searching for an engine coolant thermostat for a 2002-2006 Jeep Wagoneer should be aware that this model was not produced during those years. The original Jeep Wagoneer (SJ) production ended in 1991. The name was briefly used in 1993 for a luxury version of the Grand Cherokee (ZJ) before being discontinued again. The Wagoneer and Grand Wagoneer nameplates did not return to the market until the 2022 model year.

Are You Driving a Different Jeep?

- Jeep Grand Cherokee (WJ/WK)
- Jeep Liberty (KJ)
- Jeep Wrangler (TJ)
Please double-check your vehicle's model and year before searching for parts. The Jeep Grand Cherokee is the most likely model to be confused with a Wagoneer.
General Information on Thermostat Failure
While we cannot provide specifics for the requested vehicle, here are common symptoms of a failing thermostat that apply to most vehicles, including the Jeep models from that era like the Grand Cherokee.
Symptoms of a Bad Thermostat
- Overheating Engine: If the thermostat is stuck closed, it will prevent coolant from reaching the radiator, causing the engine to overheat. This is a serious issue that requires immediate attention.
- Low Temperature Reading and No Heat: If the thermostat is stuck open, the engine may not reach its proper operating temperature. This can lead to poor performance, decreased fuel economy, and a heater that blows cold or lukewarm air.
- Erratic Temperature Fluctuations: The temperature gauge may swing from normal to hot, or vice-versa, indicating the thermostat is not opening and closing correctly.
- Coolant Leaks: Coolant may leak from around the thermostat housing.
