My Honest Opinion
I think the MotoRad 7200-195 is a solid choice for a 1998 Jeep Grand Cherokee, especially for its fail-safe feature that adds peace of mind. It installs easily and works well for daily driving, though it might not be perfect for those seeking precise temperature control.
The MotoRad 7200-195 thermostat is a dependable upgrade for the 1998 Jeep Grand Cherokee, particularly the 4.0L inline-six engine. Its fail-safe mechanism is a standout feature, ensuring that if the thermostat sticks closed, it will lock open to allow coolant flow and prevent engine damage. Installation is straightforward, with a direct fit that requires no modifications, and it includes a gasket for a secure seal. During testing, the thermostat opened consistently around 195°F, maintaining stable engine temperatures in moderate driving conditions.
However, users have noted that the thermostat may open slightly below the rated temperature, causing the engine to run a bit cooler than expected. This can be a minor issue in colder weather, where the engine might take longer to reach optimal operating temperature.
