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.

  • OE-engineered: manufactured for exact form, fit and function to help maintain cooling system performance.
  • Brass and stainless steel construction with a standard-design element.
  • Calibrated open point: starts to open at 82°C (179.6°F).
  • Includes a jiggle-pin check valve to help bleed trapped air, plus a gasket/seal.
  • Sealing flange: 52.0 mm outside diameter, 27.0 mm flange height. Made in Japan.

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.

Frequently Asked Questions

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.
