Ginetta G40 Maintenance Routines

The following routines describe checks and maintenance for a car used to full potential on track, and also occasionally on the road.

Oil changes

  • Approx. every 2000 miles

Brake fluid change (or caliper bleed)

  • Every two or three track days

Spanner check

Before any track excursion, test the tightness or level of the following in particular:

  • Bolts holding the alternator
  • Bolts through the wishbones at the front
  • Wires into the alternator and on other side of engine to starter motor
  • Clips holding the airbox together (they can come off and you'll fail a noise test for induction noise)
  • Exhaust clamps - just after the manifold, 1/3 along the side pipe, at the joint by the rear wheel
  • Clips holding the boots on the CV joints at the rear
  • Wheel bolt torque
  • Oil and other fluid levels
  • Tyre pressures equal all around
  • Damper settings equal side to side
  • Hose clips on the cooling system
  • Mounting bolts on differential (tighten, see bottom of page for picture)

Oil catch tank

  • Empty the oil catch tank after every track day

Air filter

  • Remove, clean (with warm, soapy water) and re-dry the air filter after every four track days

Air conditioning

  • Run the air conditioning to cold once a month

Known issues (bearing in mind this is a racing car, so some of these things will happen regularly)

  • Exhaust movement (over time, the middle clamp below the passenger door allows movement of the system backwards)
  • Alternator weakness (early types)
  • Alternator upper mounting bolt breakages
  • Alternator battery charge cable breakages
  • Fuse changes very difficult (old dashboard)
  • Do not use a plug-in 12V compressor for inflating tyres; it will blow a 5A fuse and stop the car starting
  • Brake bleed screw on rear calipers sieze, paticularly on the side near to exhaust s- do not over-tighten; try to keep in a heated garage
  • Rear-view mirror fals off, if stored in non-heated garage
  • Clutch is single-plate and can't take repeated practice starts
  • Differential mounting bolts come loose (need regular tightening - 10 mm hexagon key to approx 25 n/m)
