Despite being subjected to excessive heat and cold, radiator hoses tend to last a long time without needing
replacement. Regardless of a typical long life, it’s a good idea to inspect them for condition every time you
have an oil change. It’s a simple inspection. Just squeeze the hose with your hand. It should be firm and
resilient and rebound firmly. If the hose is soft or conversely brittle, replace it.
Brakes: Brakes are always operating under high temperatures because of their
very nature. Brake shoes and pads are designed to create friction in order to stop
the motion of the wheels, which are attached to the brakes. This friction
produces intense heat. Add the higher temperatures of summer and (if under
extra load) the increased braking required when towing a trailer and it’s like
having a blast furnace attached to your wheels,
Have the brakes checked in the hot summer months (every tire rotation or
6,000 miles).
