Having just spent a decent wedge having work done on the engine to cure an overheating issue, also a rebuild of the driver\u2019s electric window, my father took the car for a drive on a sunny summer day, mid 2001.<\/p>\n\n\n\n<p>When it got to being a bit longer than expected, my mother and I weren\u2019t that surprised when an AA flatbed trundled up the street. The electric window had jammed down, after being opened to let the extra heat out, the extra heat coming from running the blowers full chat to try and add cooling to an overheating engine.<\/p>\n\n\n\n<p>Many 4 letter words were thrown at the car, it was allowed to cool in the street, then driven in to the garage where it was left to think about just what it had done.<\/p>\n\n\n\n<p>Hence my priority number 1, was to try and check the overall health of the engine. Pulling the radiator cap, I wasn\u2019t entirely surprised to find it was not full to the brim. Some crystallising and residue left in it wasn\u2019t that much of a surprise. When I removed the top hose and plugged the radiator boss and the thermostat boss with rubber gloves, I discovered there was still coolant in the system though.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"1000\" src=\"https:\/\/mcnab-racing.co.uk\/wp-content\/uploads\/2021\/12\/img_3830.jpg\" alt=\"\" class=\"wp-image-1023\" srcset=\"https:\/\/mcnab-racing.co.uk\/wp-content\/uploads\/2021\/12\/img_3830.jpg 1000w, https:\/\/mcnab-racing.co.uk\/wp-content\/uploads\/2021\/12\/img_3830-300x300.jpg 300w, https:\/\/mcnab-racing.co.uk\/wp-content\/uploads\/2021\/12\/img_3830-150x150.jpg 150w, https:\/\/mcnab-racing.co.uk\/wp-content\/uploads\/2021\/12\/img_3830-768x768.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p>For a long time I have felt the cooling system has a glaring issue on the car and in other engine bay shots I\u2019ve found online and on local racecars I\u2019ve managed to have a nosey round, they have taken steps to address or mitigate this.
