Age can often take it’s toll on the engine; upon further inspection, things that look and function perfectly fine can often be showing signs of wear and tear.
Take the cooling hoses for example. The engine runs and functions as you’d expect but as you’ll see from the images they can be just a fraction away from causing longer lasting damage.
Here is one of the hoses from our 1971 Triumph Spitfire.
Another one of the hoses had lost its flexibility entirely, this is not a good sign. When rubber no longer flexes it is time to renew. What makes this example worse is that the tube has expanded too.
