How To Build Engine Test Stands

It is a bit costly to have an engine test stand. Aside from that, you also need to carefully account for some adjustments because of the varied engine sizes. If your budget is tight, you can opt to assemble an engine test stand out of some easy-on-the-pocket parts. You just have to know which of those parts are specifically matched to the engine that you wish to test. Here are some useful hints on how you can build an engine test stand:

  • What is an engine test stand?  It basically permits you to operate an engine even though you are not inside the vehicle. You run the test so you can readily discover the presence of any engine defect or malfunction. After your discovery, you can plan to fix the problems without the necessity of working around the rest of your vehicle.
  • What are the requirements of an engine test stand?  There are several components involved in building an engine test stand. You need to be familiar with them in order for you to efficiently operate on your engine. Your engine motor requires electricity, a cooling device, an exhaust, and some gauges.
  • What are the procedures involved in running an engine test stand?
    • Use your engine hoist to easily lift your engine. Raise it up to an appropriate height, ideally about 4 feet above the ground.
    • Construct a metal frame around your engine. You can improvise the frame by using two metal pieces. Each metal should be 4 feet long and a square inch thick. Position them vertically close to the back of your engine.
    • Check out the bolts on the end mounts of your engine. Attach them into the pieces of metal. Be cautious here. Make sure that the lower parts of the each metal are properly placed on the floor. Follow the same procedure when you work on your front engine mounts.
    • Bring out some metal strips, about four pieces. Weld them directly to the foundation of your metal rods. This allows you to create a strong base around your whole engine. Then, proceed by releasing your engine from its hoist.
    • Take care of your tachometer, water temperature gauge, and oil pressure gauge by drilling three holes through a wooden block. See to it that the holes correspond with the respective dimension of the gauges. Set the gauges and secure them with screws. Continue by plugging the wires into the engine sensors. Actual sensor placements may differ based on design.
    • Mount your muffler, including its tubing, directly into the port. Fasten your muffler so you can generate enough exhaust during your testing.
    • Tie up your radiator to the metal frame. Then, start running hoses from it to prevent overheating. Double-check the water temperature by referring to the extra sensor attached to your radiator.
    • Position your car battery just below your engine test stand. Connect the ground and hot cables to their respective engine block points. Your car battery powers your engine. You really don’t need to have an alternator. And finally, turn on your engine and conduct the necessary tests.

A good substitute for a metal frame is a wooden frame. Just make sure that its heavy enough to bear the weight. While running the test, provide enough ventilation.
