Coolant leaks can normally be temporarily repaired with heavy duty adhesive tape, hose and clamps.
If a serious oil leak occurs, shut down the engine immediately and try to find the cause. Oil leaks are a lot harder to repair
temporarily because of the pressure involved. However, if the main flow can be stopped to a drip or dribble, place a can
underneath the leak and replenish the engine with new oil (from a spare oil can) at the same rate as the loss.
Drip trays of metal or glass fiber should be used beneath the engine to stop lubricating oil or fuel oil dripping into the
bilges. Care must be taken to avoid galvanic action between the drip tray and engine (e.g., a copper tray should not be
used under an aluminum alloy oil pan). Remember to keep the drip tray clean because this provides an early indication of
leaks.
