[QUOTE="supermini, post: 1382705, member: 30887"] Do you mean that the fan is run by a belt connected to the pulley? Mmmm:confused_smile: That's Strange. What model of proton is this? They should only have electric fans as most FWD configured vehicles. There is a lack of space and the engine sits sideways in the engine bay unlike RWD models. To answer your question, as long as you have the correct diameter fan installed to suck out or blow out the hot air running through the condesor, no problem! Clutch fans should not effect your engine power. How it works? The pulley is constantly turning, The fan is built with a heat activated clutch mechanism. The clutch inside the fan expands when hot causing it to tighten up and spin. It releases and stops spinning when the clutch inside the fan cools down. This action should not effect your engine power. These fans are usually used in RWD configured cars to cool the radiator, not the Air cond condensor. The Air cond condensor usually useses and additional electric powered fan. The lack you feel should be coming from your air cond compressor. Is it OEM or you've replaced it with something similar? It may need to be replaced again or serviced. Another thing with modifiying the fans, make sure you have no gaps inbetween the fan and the condensor otherwise, the airfolw will be disrupted causing the condensor to overheat resulting in impropper cooling inside the cabin. Also, these causes the main pipes running to the condesor to overheat and leak.... My advice, if it ain't broken, don't fix it!:angel_smile: [/QUOTE]
