Slipping belts or collapsed hoses mean trouble. google_ad_height = 15; A puller fan on the other hand sits right behind the radiator. The controller (low power) controls a relay (high power) Mounted on the engine side of the radiator, a pull fan does not interfere with airflow at highway speeds. Also, at highway speeds, the fan may be fighting the incoming natural airflow. 8. //-->. A pusher fan sits in front of the radiator. A 16-pound cap raises the boiling point to 268°F. /* RT66-Link728x15 */ - these are regular fixed blade fans that have a free wheeling clutch mechansim that when a specified temperature is reached, using power needlessly. in. /* RT66-Link120x90 */ It allows you to turn your thermostat up a few degrees. Copyright 2021 Standard Motor Products, Inc., Designed & Developed by Multimedia Solutions You need sufficient openings to the radiator that channel adequate air to the entire surface of the radiator. An example of a typical cooling fan shroud, which directs air where it's meant to go. You can't A pusher-style fan can be used as an auxiliary cooling source, but you should sure make the fan covers as much of the radiator … These improve the horsepower and torque delivered to the wheels by eliminating the parasitic drag of the stock belt-driven fan. Shrouding your radiator lets the fan pull air through the entire core. purchase reasonably priced simple to install electric controllers from any parts house. As the water pump turns via a rubber belt connected to the cranshaft, the fan rotates. Copyright 2020 Standard Motor Products, Inc., Designed & Developed by Multimedia Solutions Plan adequate space for the cooling system including the radiator, fan, shroud, overflow tank, and mounting brackets. to the wheels and not be wasted on accessories. All engines have "normal" operating temperatures. Independent tests have shown that even with a pusher style fan mounted only 5/8 of an inch away from the face of the radiator, there is still a vast amount of air that escapes from around the skirt between the radiator and the fan blades. When planning your performance vehicle, remember that you're building it to drive, not to sit and steam. in. The use of a coolant that contains no silicate is recommended. There are two modes of operation on most electric fans and they are categorized by the direction of air flow through the radiator: Pull fans: these fans pull air through the radiator and are located on the engine side of the radiator. To obtain the maximum operating efficiency rate for your water pump at highway speeds, you should overdrive the pump by 30-35%. Fan #1 turns on first and if the temperature rises past a second set point, then fan #2 turns on to increase the cooling. If you are having cooling problems, begin by looking at the least expensive fixes first. If your engine is designed to run at 200°F, a 14-16-pound cap should be sufficient. You can install two small fans side by side and add their CFM rating together to create a "big" fan. when it is needed. Contact . The result is that once the engine is warmed up, the engine temperature gauge is rock steady - very little movement as you google_ad_slot = "6369798871"; Electric fans use less power than a mechanical fan and are the choice where gas mileage is a concern and if you want to make sure that the most engine HP gets The pressure cap matters. They are often called flex fans. Order Electric Radiator Fan - Universal for your vehicle and pick it up in store—make your purchase, find a store near you, and get directions.

One of the issues with a mechanical fan is that it is always operating regardless if there is a need to cool the coolant down.
