Uprated Ford Sierra Cosworth Fan Switch

Motorsport Developments

Fits:Ford Sierra CosworthAs many of you will know, the YB Cosworth cooling fan circuit is not really suitable for the amount of current the fans draw when on for long periods of time and this leads to the fan circuit overheating the fuse connector and relay terminals, resulting in a no fan situation.Secondly, on many cars, when the fans DO actually work, they often come on too soon, and then won't go off when you are moving. That's because the original system was a little close to the bone to start with and whilst on the standard radiator it is not always too much of a problem, put an aftermarket radiator on and you will run into switching problems such as the fans will stay on even on the motorway at 70mph. This is due to the heatsink effect from the alloy end tanks and the current draw from the system often leaves the ECU and fuel system circuit with woefully inadequate current supply, leading in some cases to damaged engines!This switch will usually switch on your fans at around 91 degrees C and off again at around 87 degrees C.It works the best and closest to those temperatures in an uprated alloy radiator, but it is a good upgrade for normal radiators too in my experience, working around 93/90 in standard radiators.We have fitted and sold literally thousands of these units with not one unhappy customer, so get those power sapping fans to work properly this summer.Please note:The switch you receive will be a different colour to the one pictured. This is a stock picture which, interestingly, lots of traders have copied. Are they actually selling you the right part? Take care out there...
