The temperature gauge is designed to let you know what is happening in the cooling system. To let you know in advance if something is wrong. The gauge should always start on the cold when the engine is first started, then climb to a normal operating temperature after running for about 30 minutes.
THINGS TO LOOK FOR
Gauges must be seen at all times. They must move from one value, being cold, to another value, being hot. If the gauge stays on cold or doesn’t move then this is a warning sign. Get it checked ASAP. The same applies if the gauge stays on hot or just in the middle. If a gauge climbs 3/4 of the way the engine should be switched off and then wait for at least 30 minutes before checking the water. Every minute of driving a vehicle on high may add a $100.00 to the repair of the cooling system.
IS IT EXPENSIVE TO REPAIR?
Temperature gauges can be expensive. The wreckers is an option.
