Coolant and your vehicle

The cooling liquid in your engines system does
a lot more than just keep everything running a consistent temperature.
Coolants' main functions are to; raise the boiling point, lubricate engine seals to prevent them becoming brittle and to also prohibit the build up of rust.
Overlooking something as simple as the coolant could result in the failure of a $5 seal with the collateral damage in the $1000's.
This being the case with the Volvo (right).

Regular servicing ensures the basics such as coolant and lubricant levels are checked properly. Low levels could indicate a leak or fault which can easily be rectified but if ignored will cause problems and perhaps the inconvenience of being stranded 'somewhere in the great outdoors'.
