1.9cdti mine reaches 100 and still no fan

 

[PaulEll]

Have you ever heard the fan cut in?? You tested it to make sure it works???

 

[mr.d]

it only ever did it once before a few weeks ago since then it has never kicked in.

 

[blink]

unless you get the coolant warning light, i wouldnt worry about it

Turn your heaters on full and see if it cuts in. Aslong as the engine temp doesnt go much higher than 100 you'll be ok for now

Take your fan off if you can, if not, connect it to a direct power, ie a wee 12v smoke alarm battery and see if it spins, if not you know its goosed

putting the heaters on full will reduce the temperature of the coolant, reducing the demand for the radiator fan, its a good way to keep going when your car starts to overheat

i did that last year in 27C heat, was sweating like Gary Glitter in a court room!

Full heat and open the windows and all that lovely heat just bellows out lol. Thats why i got bonnet lifters, paranoid about over heating. Got new water pump, thermo and cooling at 40k lol

It depends on the engine type.
On mine Z16XEP the coolant needs to go up to 112 or 113 for the fan to kick in. Then it drops to 105. It normally runs at 108 C.

If your derv is reaching 100 degrees regularly then I would look into reason why, my 15 months of owning the 1.9 and the fans have never kicked on, and the engine normally runs at 80 ish, highest I've seen it is 84 with a little enthusiastic driving, but still no fans.

dont think i have seen mine over 101, but i dont look that often, the 2nd fan comes on if the car is stationery though after a while, you cant hear the 1st stage fan when its running, however.

 

[Cal91]

I have never heard the fans on my 1.9 kick in the whole time I've owned it.

I'd quite often hear my other cars kick in.

 

[blink]

you might find one fan is running, the one you cant see from the engine bay, it should run with the a/c on too

 

[raffy]

mine never goes over 90 c then drops down to about 85 c when on the move is this normal ?

 

[astra_life]

Never seen the fan kick in on my 1.7 and I was bleeding the cooling system at the time and then decided to see if it would kick in, waited 45 Ish minutes after the blessing was done still no fan and the fuse and relays are fine, ( I know the thermo opens at 93c only ever seen the engine get to that temp once)

I 've changed my thermostat twice because it was stusk open. The first time temperature never reached 70 C and the second time it went up to 90-95 C. You should ask a garage the normal temperatures for your engine type and see if the thermostat works properly.

Z16XEP running normally at 108? Really? Mine would run at around 92 when I had it. Very rarely would it hit 100 :sus:

Agree with this. My Z19DTH runs around the 83-84 mark most of the time... with that said though, I have seen mine his 137. It proceeded to then die approximately 30 seconds later :lol: Bloody radiator burst

I was thinking about this tonight. I went out this evening and got back home, 2 hours later I decided to top up my washer fluid and when I opened my bonnet the engine was still warm. I have also never heard my fan. I was concerned at first that the engine was still warm but i suppose a dash light would appear if the engine was overheating or if the fan was broke.

 

[blink]

they stay warm for hours and hours

 

[McBride]

how do people know what temp the cars at when the fan kicks in ?? in other words how do you display the temp.

my fans on all the time, only have be sat in a traffic jam for 5mins and its on
