Clamps & Fasteners

What are clamps and fasteners?

Every small detail in a vehicle is necessary for its performance. While a fuel system is made up of various components integrated and working together for a more efficient drive, even the smallest parts become necessary in ensuring that the engine operates smoothly and ideally. Some of these are clamps and fasteners that work hand in hand with the rest of the vehicles components.

What are the different types of clamps?

In a vehicle, clamps used are hose clamps which are meant to attach and seal a hose into a fitting like a barb or nipple.

  • Spring clamp – Also known as constant-tension clamps, these apply constant tension on the rubber hose and is the common choice in factory-issued vehicles.
  • Worm clamp – Usually replaced by mechanics when a spring clamp isn’t available however not advised because of their adjustment slots which can fray the hose.
  • Racing clamps – Provides 360 degrees of tension all around the hose’s diameter and made of stainless steel, these become the top choice of replacing original factory spring clamps but are expensive and can be difficult to find.

What are the different types of fasteners?

Fasteners are also vital components in the overall performance of the vehicle, holding everything in place using a non-permanent joint.

  • Nuts – A temporary joint created with a bolt and washer
  • Bolts – Held by a nut with a shoulder and are stronger than screws and used for less permanent components
  • Washer – Provides the nut a flat surface to fasten with a bolt and also used to protect the material in the nut side
  • Screw – More permanent in fastening materials together and is not used with a nut

How to loosen hose clamps?

Hose clamps are normally found in the vehicle’s cooling system and are fairly easy to loosen.

  1. Drain radiator thoroughly – Turn radiator petcock counterclockwise to open and drain the contents in a bucket. Tighten the petcock to close.
  2. Loosen screw on clamp – With a nut driver or screwdriver, loosen the screw on the clamp by turning it counterclockwise all the way to remove the clamp while leaving the hose intact.
  3. Squeeze vertical tabs on clamps – With a pair of pliers, squeeze the tabs on the radiator hose clamps to spread it out and reposition the clamp down lower to the hose towards the neck junction of the radiator.
  4. Pry hose off the junction – Pry off the hose and with the same pair of pliers, squeeze the tabs again and remove the clamps from the hose.
  5. For wire crimp style clamps, loosen the tightening screw – Loosen the screw with a screwdriver but only to a certain point because of the clamp’s nature. Once loose, pry the hose off the junction and remove the clamp from the hose.
