New water pump for MGF and MGTF. Fits all K series engines including 1.1, 1.4, 1.6 & 1.8 litre variants fitted to Rover 200, 400, 25, 45, 75 and MG ZR, ZS & ZT. As it's a cam belt driven pump it's a good idea to change the pump when replacing the cam belt as the act of tensioning the belt can cause an old pump to fail.
