Funnel Holder

When pouring viscous liquids such as oil or antifreeze, a regular funnel often drips and creates a mess. A dedicated funnel holder provides a secure place for the funnel while excess fluid drains into a catch cup, keeping your workshop floor clean.

  • Metal holder with stainless‑steel catch cup
  • Fits funnels 8–18 in tall (opening 2.83 in)
  • Mountable to the wall with graduated holes

LED Headlamp

Working in cramped, low‑light spaces is easier with a modern rechargeable LED headlamp. The Biat model offers a 230° light strip, side spotlight, motion‑sensor activation, and six lighting modes, all powered by a 1,200 mAh battery.

  • Wide‑angle and spotlight modes at two brightness levels
  • Motion sensor for hands‑free operation
  • Adjustable elastic headband fits most heads

Hardware Organizer

Small bolts, nuts, and screws disappear quickly in a busy garage. The Boltster silicone mat uses a honeycomb pattern of openings to hold hardware securely, even if the mat is dropped.

  • 10 in × 10 in mat with holes for 7 mm–17 mm pieces
  • Heat‑ and chemical‑resistant silicone
  • Color‑coded (red, blue, green) and includes a hanging hole and label pad

Oil Filter Wrench

Stubborn oil filters are a common headache. A band‑style oil filter wrench, like the Craftsman model, wraps around the filter and provides extra leverage for safe removal.

  • Fits multiple filter sizes
  • Band design prevents damage to the filter housing
  • Use only for removal—not for installing new filters

Radiator Cooling System (Why It Matters)

Understanding the radiator’s role helps you choose the right tools and fluids. The system moves coolant from the engine to the radiator, where heat is dissipated, preventing overheating.

  • Thermostat detects excess heat and signals the coolant pump
  • Coolant circulates through engine passages, absorbs heat, then releases it in the radiator
  • Regular maintenance of the radiator ensures reliable engine temperature control
