Geezerjobber Posted October 18, 2022 Share Posted October 18, 2022 Aircom compressor not working can I bypass it with smaller belt, rather than replacing pricey aircon? Td5 defender 2000plate Quote Link to comment Share on other sites More sharing options...
Phill B Posted October 21, 2022 Share Posted October 21, 2022 Definitely can on (some) other cars. Doubt you can on a 200tdi though as the water pump pulley is in the way. Bypass the aircon and the belt can't get around the water pump pulley on the way to the idler pulley. I could be wrong. Quote Link to comment Share on other sites More sharing options...
simonr Posted October 21, 2022 Share Posted October 21, 2022 Do you need to bypass it? The pulley on the AC Compressor has a built-in clutch which disconnects the pump when the AC is off. (unless that's what's bust?). Leaving the belt running over the compressor will make a trivial difference to the overall efficiency of the engine, no more than the idler pulley. 2 Quote Link to comment Share on other sites More sharing options...
