How To: Check a used car for leaks before buying

Engines can be rather complex pieces of machinery. Comprised of several thousand components that all need to work together in harmony so that the engine can provide the power needed to propel the vehicle. Some of these parts need lubrication, other need cooling. As such, there are various channels and pipes that will feed the engine these liquids and various components need to seal against other to keep these fluids in.

Over time, some of these joints, connections and seals may perish, allowing fluids to escape. This can sometimes be a warning sign and sometimes it's a minor inconvenience.

We take a look at how you can go through the engine and what to check for when it comes to leaks, ensuring peace of mind before you purchase.
