Aux Belt Idler Pulley - Gates T36204

An aux belt idler pulley's primary function is to guide the v-ribbed belt, maintain proper belt tension, and help manage belt wrap around other accessory pulleys in the engine.

Signs include squealing or chirping noises from the belt, visible wear or damage on the pulley surface, excessive wobble when the engine is running, or intermittent failure of accessories driven by the belt.

The pulley has a width of 25 mm, an outer diameter of 70 mm, and an inner diameter of 8 mm. The bolt diameter is also 8 mm.

No, this pulley is specifically designed for certain Ford models, including the Fiesta Mk5 ST150, Ranger TKE, S-MAX, Mondeo Mk3, and Mk4. Always verify compatibility with your vehicle's specific make, model, and year.

It means the pulley's role is to change the direction of the belt (deflection) and keep it running smoothly on its path (guide), ensuring optimal contact with other pulleys.

While possible for experienced DIY mechanics, it's often recommended to have it replaced by a professional. Proper belt tensioning and alignment are critical for the system's longevity.

Check the condition and tension of the auxiliary belt. Inspect the idler pulley (Gates T36204) for wear, damage, or wobble. Replace the pulley and/or belt if necessary.

Ensure the auxiliary belt is properly tensioned and aligned. A faulty idler pulley can affect belt performance. Inspect the pulley for smooth rotation and proper seating.

A worn or improperly installed idler pulley can cause vibrations. Verify the pulley is securely fastened and rotates freely without excessive play.

Ensure you are using the correct bolt size (8 mm) and that the pulley is aligned correctly with the mounting bracket. Refer to vehicle-specific repair manuals if needed.
