Question about fan shroud

[Phoenix7]

ok I like everyone's posts for different reasons.

Here is my take on it:

If your stock fan is working properly then leave it alone. You need the shroud in order to maximize the air-flow through the radiator (assuming you still have the stock underbelly tray and ducting in front of the radiator). If you remove the stock shroud you will overheat the car when it's idling or cruising at low speeds ( stop and go traffic) since the shroud can't help the fan pull all the air out.

If you know your stocker is toast then you can go with an Efan (cheaper than OEM replacement) but you should still have a shroud. You need to make sure the new Efan pulls at least 2100cfm. An improperly installed fan (running all the time) WILL kill your alternator so look into a good setup ( i have a 35A breaker, relay and thermosensor) to ensure you aren't drawing too much power at fan startup (fans tend to "spike" and draw much more amperage when they first kick in).
