AISIN Engine Coolant Thermostat P/N:THS-006
Keep coolant circulating at the right temperature with the AISIN Engine Coolant Thermostat (THS005). This standard-design thermostat drops in as a direct-fit replacement for the 1999-2003 Chevrolet Tracker [L4-2.0L], 1999-2000 Suzuki Esteem [L4-1.8L], 2010-2012 Suzuki Grand Vitara [L4-2.4L], 2010-2012 Suzuki Kizashi [L4-2.4L], and 2010-2012 Suzuki SX4 [L4-2.0L]. It regulates coolant flow between the engine and radiator to help the cooling system reach and hold its normal operating range.
If a stuck thermostat is behind overheating, a slow warm-up, or a temperature gauge that swings, this engine coolant thermostat replaces the failed original.

This part cross-references / interchanges with the following part numbers:
What is an engine coolant thermostat and what does it do?
It regulates coolant flow between the engine and radiator, staying closed during warm-up and opening as the engine heats so the cooling system holds its normal operating temperature range.
What vehicles does the AISIN THS005 fit?
It fits the 1999-2003 Chevrolet Tracker (L4-2.0L), 1999-2000 Suzuki Esteem (L4-1.8L), and 2010-2012 Suzuki Grand Vitara, Kizashi, and SX4. See the Buyer's Guide tab to confirm your vehicle.
At what temperature does this thermostat open?
It starts to open at 82°C (179.6°F), per the manufacturer specification.
Does it include a gasket and a jiggle pin?
Yes. A gasket/seal is included, and the assembly features a jiggle-pin check valve that helps bleed trapped air from the cooling system.
What are signs my thermostat may need replacing?
Signs include engine overheating, an unusually slow warm-up, or a temperature gauge that swings. Diagnose the cause first, since these symptoms can have other sources.
