Is your engine running hotter than it should, especially in traffic or on slow climbs? The problem might be your fan clutch. This Four Seasons 36969 is a standard rotation, thermal, standard-duty fan clutch replacement. It's a completely new unit (not rebuilt) made from alloy steel for durability. The \thermal\ part means it's designed to engage more firmly as under-hood temperatures rise, pulling more air through your radiator to cool the engine down, and then disengage when it's not needed to save engine power and fuel. It's a crucial part of your vehicle's cooling system. The package contains one fan clutch unit. It's relatively compact (package is about 13.7cm H x 18.8cm L x 19.1cm W) and weighs around 1.2 kg. Noise level is rated at a quiet 14 decibels. Before ordering, make sure this is the correct part number for your specific vehicle's make, model, and engine. Replacing a worn fan clutch can make a huge difference in your engine's operating temperature and overall health.
