Automotive Workshop Equipment

Automotive workshop equipment finds a vehicle's fault without stripping parts and carries out its service: testers for engine sealing, fuel and oil pressure, the cooling system and the battery; brake fluid and transmission fluid exchange kits; oil filter wrenches; tyre inflation, gauging and repair tools; booster clamps.

Measure before you strip

On the engine, three tests separate most faults. A compression test shows each cylinder's pressure and the spread between them. A leak-down test finds where a weak cylinder is losing it -- valve, rings or gasket. Fuel and oil pressure tests give the pump and regulator figures.

On the cooling system a pressure tester brings the radiator and hoses up to working pressure and makes a leak visible; a smoke leak detector finds small vacuum and EVAP leaks by the trail of smoke. A battery tester loads the battery at cranking current (CCA): a battery a voltmeter calls full can collapse under load.

Fluid service and filters

Brake fluid absorbs moisture and its boiling point falls with time; a brake fluid tester shows when it is due, and an exchanger swaps old fluid for new without letting air in. Automatic transmission fluid kits come with adaptors for draining and filling by vehicle type.

A cap-type filter wrench is the cleanest answer but fits one filter size; you need the diameter and flute count. A workshop that sees many makes is better served by adjustable chain, strap or three-leg wrenches and cap sets.

Frequently Asked Questions

  • What is the difference between a compression test and a leak-down test?

    A compression test shows how much pressure a cylinder makes; a leak-down test shows where pressure escapes. Measure compression first, then leak-down the weak cylinder.

  • Which vehicle does a cap-type filter wrench fit?

    The cap is made to the filter's end diameter and flute count. The product page gives the size; send us the filter code with a quote request and we match the cap.

  • Why does the current rating of a booster clamp matter?

    It is the load the clamp and cable can carry. A diesel or heavy vehicle draws more cranking current than a car; an under-rated clamp heats up and will not start it.
