What the AI looks for in Automotive Replacement Engine Fans & Parts

Drive type
Replace like with like: belt-driven mechanical fan (clutch plus blade) or electric fan assembly, unless you are deliberately doing a conversion Mixing parts from the two systems, such as a spacer on a clutch-equipped engine, causes fitment and cooling failures.
Vehicle and engine match
Match year, engine, and A/C or towing package. Cross-reference the OE part number rather than trusting a generic fitment list Fan diameter, clutch duty rating and connector type often change within one model year depending on engine and options.
Diagnosis first
Confirm the failure before buying: clutch that freewheels or leaks, fan motor that does not run when commanded, a blown relay or fuse, or a bad sensor Overheating at idle has many causes, and buying the wrong part is the most common wasted spend in this category.
Shroud and clearance
Keep the original shroud and keep blade-to-radiator and blade-to-hose clearance A fan without a shroud moves far less air through the core, and contact damage is immediate.

Questions

Should I convert my mechanical fan to electric?

Only if you have a reason such as space, a swap or a build. A healthy OE clutch fan usually cools better at low speed and when towing than a mismatched electric kit.
