Coolant Hose Check: 1999 Mercury Mountaineer 5.0L V8

The video above shows to check the coolant hoses in your 1999 Mercury Mountaineer. The coolant hoses (radiator hoses) carry engine coolant through your engine and will eventually wear out. You can avoid getting stranded by identifying signs of extreme wear before they break. In 1999 Mountaineers with the 5.0 liter engine, coolant leaks are most likely to occur where the hoses connect to the engine, but it can also leak from the reservoir or from the hoses. Look for cracks in the hoses and analyze the brittleness or squishiness of the hoses in your Mountaineer - if the hoses are hard to squeeze or squeeze very easily, it's time to replace them. Instead of using a hose diagram, this video shows you where coolant hoses on your 1999 Mountaineer with the 5.0 liter engine are located and the steps needed to analyze them.

Never attempt to replace a hose that is connected to your air conditioner – these hoses contain refrigerant that is under pressure and can blind you. AC problems are always best left to your professional mechanic.
