Timing belts on schedule
Many engines use a timing belt with a replacement interval listed in the owner's manual. On some engines a broken belt causes serious internal damage, so replacing it on schedule costs far less than waiting. We look up your engine's interval and replace the water pump at the same time when it makes sense.
Overheating is urgent
If the temperature gauge climbs into the red, pull over and shut the engine off. Driving an overheating engine can warp the cylinder head and turn a hose or thermostat repair into a major one. Call us and we will help you plan the next step.
