The shroud is designed to fit factory mounting points and will suit a range of aftermarket radiators, however spacing will vary depending on tank width. We only stock the 2024cfm fan, but both models are readily available, and we encourage International Customers to source theirs locally to save on shipping costs and for warranty purposes.Ĭomes with SPAL 30130012 one way flaps x7.Ī mounting kit can be added for convenience. Most people that have cooling problems with a belt-driven fan at idle and slow speeds don’t have a shroud their fan is drawing very little airflow through the radiator, and most of their cooling comes from ram air being driven through the radiator at speeds above 40 mph. The shrouds have mounting points for the factory temperature switch wiring and connector.

This is a great upgrade to these cars as they were not designed for stop and go.

The series 2 have a plastic tank radiator and the shroud mounts on the top and sides. However, if you add a shroud you are now cooling 100 of the radiator core, which allows you to make more horsepower. Brand New radiator fan shroud for MGBs using mechanical fans 1962-1976. The series 1 had a factory aluminium radiator and the shrouds mounts on the sides. This is to accommodate normal engine and radiator movement, and also the flex that occurs in the fan blades at higher engine rpm.Ĭhecking these measurements when running a belt-driven fan and a fan shroud will solve overheating problems and fan contact problems caused by improperly placed fans and shrouds.Custom made, CNC cut, 3mm Aluminium radiator shrouds to suit Nissan Skyline R32/33/34, designed to mount SPAL 16' fans part number 30102049 (2024cfm) and 30102113 (3000cfm). There should be at least 1 inch of clearance between the two. The last measurement you should check is the distance from the face of the fan to the radiator. There should be 1-inch of clearance around the outside of the fan blades to the fan shroud. Among the most significant benefits of selecting Toyota OEM parts is that they provide a. This can damage the fan shroud and the fan. Advantages of Choosing Toyota Genuine Engine Cooling Fan Shroud Parts. If there is not enough clearance, you run the risk of the fan contacting the shroud with natural engine movement and body flex that affects the radiator and fan shroud mounting. If there is too much space here, the fan won’t be as efficient as it could be in pulling air through the radiator. The other very important fan to fan shroud measurement is the distance around the circumference of the fan and the circular opening of the shroud. This causes dissimilar resistance along the length of the fan blades, which stresses them. Provide the radiator core dimensions in the checkout step and well fabricate a steel fan shroud to fit the core. It’s also important that the fan blades do not extend past the top, bottom or sides of radiator surface. Make sure you use Flex-a-lite spacers using any other brand with a Flex-a-lite belt-driven fan will void the warranty. You can use 1 or more spacers – up to 3 inches in total. We manufacture a variety of fan spacers to move the fan forward and rearward, letting you achieve the optimal position. If the blades are not far enough inside the shroud, the fan will pull air from around the shroud rather than through it. Instead it will create turbulence inside the shroud, spinning the air, but not efficiently pulling it through. If the fan is too far inside of the shroud, it won’t pull as much air through the shroud as it could. Looking from the side of the engine, the fan blades should be half in and half out of the shroud. If you have a fan shroud, the position of the fan blades in the shroud is very important to maximize airflow. Most people that have cooling problems with a belt-driven fan at idle and slow speeds don’t have a shroud – their fan is drawing very little airflow through the radiator, and most of their cooling comes from ram air being driven through the radiator at speeds above 40 mph. Without a shroud, air will take the path of least resistance, pulling air from over and under the radiator instead of through it. If you rely on a belt-driven fan for engine cooling, a fan shroud is a must to pull the air through the radiator.

The first thing we want to make sure is that you actually have a fan shroud. It’s critical that the fan be positioned properly within the fan shroud and that there is just enough clearance around the fan blades. If you’re running a belt-driven fan, there are a few things you need to do in order to maximize the engine cooling that the fan can provide.
