Hi all, I've never heard the coolant fan kick in, and with my car being a prefacelift model without the coolant temp display I've been getting concerned, so today I let the car idle for 10 mins before increasing revs to 2000 for 10 mins, fan still didn't kick in...

Coolant felt hot (from the reservoir)

Turned ac on, fan started kicking in, turned ac off, accordingly fan turned off... Should I be concerned?

If there was a problem, what could it be? My instinct is the coolant temp sensor?

^what the fan looks like on my one if it's diff in other models

it may simply not have got hot enough   try driving it quite hard, THEN letting it sit and watch for the fan..... If it hasn't overheated, I would suggest its probably fine

I've also done that and no response, I thought it was just due to it getting alot of air with the increased speed, the thing about my one is that there's no coolant temp display so I won't know when the coolant temp starts rising until the warning light comes on, in which case it'll be too late and damage has probably already been done

I have never heard any car of mine use its fan. Even on a hot summers day motorway thrash. I think Modern engines like to run hot.

you could get the wireless OBD port module (cheap off ebay I bought one from china for about £10) and download the relevent app (there's a thread recently here in the fabia II section)

 

that gives a real time temp reading from the computer....

another thing, although you have no gague, when you turn on your ignition, the red coolent warning light should show, if it does, its working, and that would come on if it was overheating....

Sathit, yes your coolant fan sounds as if it's ok. When you turn on the a/c more heat goes into the radiator from the heat exchanger so it makes the likelihood of the coolant fan coming on much greater. It does normally take some while to get the engine hot enough to get the fan to come on though if you only rely on letting it tick over to warm up. As has been said by others, go for a drive first to let it fully warm up and then let it tick over. On a cold day this may still take some time for the fan to come on. On a mild or warm day it should come on much more quickly if you just leave it running at idle.
