Low Speed Fans

[Dazandtrace]

Hi all. I need to know when do the low speed fans kick in. If I put aircon on then I get both fans running on and off. Switch aircon off. Then no fans run untill temp gauge goes over halfway. Should I have fans running low speed any other time. Hope this makes sense

Thanks Daz

fans come on at over halfway if you sit in traffic and gauge rises it comes on too cool engine down 

it shouldnt come on other than that

OK thanks. Iv got a 2.8crd voyager and sometimes the temp gauge sits a just under 3/4 sometimes only just over half and that can be at 70mph on open road is this normal

hi i got v6 petrol mine never goes over halfway but maybe thats where diesels sits 

[tomada3]

yeah if its sitting in normal range and not in red should not be problem

Hi what is normal range. As this is the first time iv owned one of these. Iv had gauge sit at 3/4 never the red.but that's under load. I have found one problem that I have rectified and that was the rad cap. Iv put a new oe part on seems to have helped. Could there be air in the system iv let car rum with cap off for about 20 mins while hot

Thanks for info

normal range is anywhere in the white you can check hoses to see if you have blockage

OK thanks I'm doing a coolant change this morning so will check for blockages and also flush the best I can.

Hi ya well iv done a coolant change plus also had a new radiator as it was blocked. Looks as if that was my over heating problem as car runs a lot cooler even under load.

So I thought while I was at it iv change oil and filter and fuel filter aswell.

Thanks everyone for the advice
