That Coolant Temperature Light is there for a good reason, it is telling you your engine is overheating due to insufficient coolant. If ignored, it can cause major damage to your engine and wallet. What should you do? First pull over and turn off your vehicle. Once the engine has cooled down you need to check your coolant level and if low get the levels back to normal. Your Coolant Pressure Light could come on for a number of other reasons as well: Heavy load hauling, cooling fan damage, radiator damage, water pump bad, broken serpentine belt or catalytic converter clog to name a few. Regardless of the reason, it is good idea to have a mechanic do a full system check for you as quickly as possible.
