Four Seasons 36986 Engine Cooling Fan Clutch

Four Seasons 36986 Fan Clutch Overview

The Four Seasons 36986 fan clutch is a standard-duty thermal engine cooling fan clutch built for front-mount fan applications. It uses an aluminum construction, non-electronic operation, and a flange mounting style to support consistent cooling fan engagement in the correct operating range.

Compatible With Isuzu Pickup, Amigo, Rodeo, Trooper, and Impulse applications, this Four Seasons Fan Clutch line part is built for direct-fit cooling service on select import vehicles. The Four Seasons 36986 is a practical replacement when the original clutch shows signs of wear, uneven fan engagement, or reduced cooling performance.

Detailed Product Description

Four Seasons 36986 is a thermal fan clutch designed for import cooling systems that rely on mechanical fan engagement. The aluminum body, 2.69 in. overall height, 2.7 in. mount diameter, and 0.63 in. pilot diameter support a precise fit on the intended application. With M6 x 1.0 hole threading and a 121.9 mm fan bolt circle, this clutch is built around the mounting dimensions commonly used on select Isuzu trucks and SUVs.

This part cross-references Gates 22087 and Walker Exhaust 55587 for the same application. It is a direct replacement option for 1986-1995 Isuzu Pickup, 1989-1994 Isuzu Amigo, 1991-1993 Isuzu Rodeo, 1986-1991 Isuzu Trooper, and 1988-1989 Isuzu Impulse. If you are replacing a worn Isuzu Pickup fan clutch or servicing an Isuzu Trooper cooling system, Four Seasons 36986 provides the correct thermal, standard-rotation configuration.

What It Helps Address

• Engine overheating caused by a weak or slipping fan clutch
• Fan engagement that is delayed or inconsistent
• Noisy cooling fan operation from a worn clutch assembly
• Reduced airflow at idle or low vehicle speed
• Cooling performance loss in stop-and-go driving

Installation Notes and Tips

• Verify the vehicle uses a front-mount fan and standard rotation before installation.
• Confirm the 4-bolt flange pattern, 4.8 in. fan bolt circle, and M6 x 1.0 hole thread match the original unit.
• Inspect the fan blades, water pump area, and mounting surface before installing the new clutch.
• Mounting hardware is not included, so reuse or source the correct hardware as needed.
• Check clearance using the 5.85 in. clutch diameter and 2.69 in. overall height during fitment.

Quality Assurance

Four Seasons 36986 is a new, performance-rated fan clutch that meets or exceeds OEM requirements. It is built as a standard-duty thermal replacement for select Isuzu cooling applications, including Isuzu Pickup and Isuzu Rodeo service needs.
