  fan and blower and its not that. I've bridged RAD1 and RAD 2 relays and the fan runs. I've disconnected the coolant temp switch and the fan runs.  Are there enough clues above for someone to offer some advise on how to proceed further as I desperately need this car on the road for my wife

• Vauxhall Astra G Petrol 1.6 - 'Using' coolant... normal? 30 Jan 2011 (Forum)
  far so good. But the very decent seeming seller volunteered that the car 'uses' a little coolant (but with no sign of any leak) but that his mechanic had told him this was normal for an Astra. I'm just slightly worried about this water 'use'. Perhaps I'm barking entirely up the wrong tree here

  I had some trouble with this about six months ago as the car was using/loosing coolant, it went to dealers no problem found, all topped up and was fine.

• 2007 Ford Focus2 1.6 petrol - Slow heater warm up 17 Dec 2014 (Forum)
  The interior heater on this car always used to warm up very quickly. For some time now, although the engine temperature gauge shows that the engine heats up very quickly, the heater can take about 15 minutes to get hot enough. There is then plenty of heat. Therer are no coolant leaks
