Buying Cooling System Parts for a 2002 Isuzu Trooper

On this vehicle, the cooling system system keeps operating temperature in the narrow band the engine was designed for, from radiator and water pump to thermostat and hoses.

  • Confirm you have the 3.5L V6 engine — every part on this page is matched to it.
  • Read the notes on each row for position, trim and spec qualifiers before you order.
  • Where labor overlaps, replace the thermostat and refill with fresh coolant whenever you change a water pump or radiator; original hoses on an older vehicle are on borrowed time.
  • Cross-reference the manufacturer part number against your old part or a service-manual listing.

Start with the largest groups on this page: Temperature Sender / Sensor and Coolant / Antifreeze .

Frequently Asked Questions

How many cooling system parts fit the 2002 Isuzu Trooper?

Our catalog currently lists 104 cooling system parts for the 2002 Isuzu Trooper across 16 subcategories and 41 brands, covering the 3.5L V6 engine. Each part is matched to the engine(s) it fits.

What are the signs of cooling system problems on a 2002 Isuzu Trooper?

Common symptoms include a rising temperature gauge in traffic, sweet-smelling steam, crusty deposits around hose clamps, or a heater that blows cold. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.

What should I replace at the same time?

Where labor overlaps, replace the thermostat and refill with fresh coolant whenever you change a water pump or radiator; original hoses on an older vehicle are on borrowed time.

What do the market flags (US, CA, MX) on each part mean?

They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2002 Isuzu Trooper was originally sold in the US, the safest choice is a part marked for the US market.

How do I make sure a part fits my 2002 Isuzu Trooper?

Every part on this page is matched to the 3.5L V6 engine. Then replace coolant with the exact specification the manufacturer calls for — mixing chemistries can gel and block small passages. The notes column carries position and trim qualifiers where they apply.
