Description Reviews We see a lot of leaky Gen 2 thermostats here at the shop. It seems like we are almost installing one. As these cars are getting older and higher mileage, all the plastic parts start to get brittle. as you try to remove the thermostat, you will very likely break the water pipe as well. So we created this kit to get both parts in one place. This kit now come with an improved aluminum water pipe! Kit Includes: MINI OEM Thermostat 11-53-8-674-895 Aluminum Water Pipe 11-53-7-589-713A When you're checking your oil, keep an eye on your coolant tank when you are checking your oil. If it's low, then you need to look down the driver's side of the motor (right next to valve cover) to see if coolant is pooling around the top brown sensor. You can also get a SES light when the sensor gets the wrong readings as well as a hard start. This part will actually stop the car from starting in certain conditions because the sensor is giving the car the wrong info (extreme temps). This is an electric operated thermostat assembly, so your car's ECU controls how it opens and closes. They also updated the harness connectors, so you may need a harness jumper to connect it to you car. If you need help, give us a call whit your VIN! The thermostat is a brand new MINI OEM part with a 2 year unlimited miles warranty from MINI. This is the latest and greatest design and will fit all Cooper or Cooper S's with the N16 or N18 motors. Since this is the latest design, you might need a new updated wire harness that we also carry here Don't forget some quality fluid! The water pipe is a brand new Aluminum Water Pipe. Fits all gen 2 cars and is the pipe that goes from the thermostat to the water pump on the back side of the engine.
