Rubber nose piece has split - barely hanging on

Wait for your car to cool down before attempting this procedure. Standing in front of your car with the bonnet open, you will see your radiator closest to the grill/front section of your vehicle. Next, follow the thick black hose running to your engine header. Closest to the header of your engine you will notice a T-piece connection section (plastic) with an electric plug on the top of the housing. The T-Piece with the plug pointing upwards, is connected to a "cold start" sensor. (Normally having 4 wires connected to it) There should be a clip holding it down in its housing. That is your hot & cold start sensor. You can remove this part and take it to your nearest parts supplier as a sample. Nearly everybody stocks them nowadays. Replace it and your troubles will be over. To remove, check for a plastic or metal split pin lookalike ( looks like a U clip as wide as the housing) just below the electric plug, on the side of the housing. Simply slide the clip out to the side using a screwdriver, and lift out the sensor using a long nose pliers. Place the long nose pliers inside the switch section and jiggle from left to right. The sensor is only sealed with a rubber O-ring, and should come out fairly easy after the clip has been removed. Replace with new and replace plug. All your cold start problems should be over
PS. Please do not remove this when the car is hot!
