Thread: Puma Defender Air. Cond. Engine fan/ noise?

Had trouble too but once I followed the "calibration procedure" it all works pretty well. From memory:

1) reset everything to zero, there's a reset menu somewhere (this was the critical step I was missing at first)
2) on each fill-up enter the number of litres used and number of kms you've done
3) you're done, however to improve accuracy repeat from 2) on subsequent fill-ups (the more the better), the litres and kms are accumulative across the fills.
4) buried in a menu somewhere is the "calibration factor", note this down for future reference and you can just plug it in if you ever factory reset your Ultragauge (I recall it is about 0.7ish for a 2.2 puma)

The readouts I have set if I remember correctly now:

I only wanted the 4 most critical readouts IMO - Engine temperature, intake temperature (surprisingly accurate on outside temperature), alternator output and boost.

Minimum you can have set though is 6 fields, so I have cab temperature (UG temp) and kilometres since last start as well, although those don't tell you much to be honest

Cheers,

Lou

just a FYI. i used to have a 2.4 and had no luck with the fuel usage, it was never accurate no matter what i did. i now have a 2.2 with a level sender that the scangauge can read. if i fill the tank to one click on the pump nozzle i can do about 100 kms on the highway before the gauge reads less that 73litres. so i guess one click is about 13 ltrs over 73 ltrs??

G'Day Gents,

I made some adjustments to the settings the other day, and now it fails to reset when I fill up...... Bloody thing....

I am now thinking of turning of ALL alarms except the temp alarm.


Thanks gents. There have been a few days that I thought mine must be broken.... :-)


Cheers,

Phill.

Whats any of this got to do with Pickles' question about fan noise?

I was wondering about that myself!
But thanks for your info & input.
I was worrried that the elec fan was on more than it should be
,but from what has been posted up, that does not appear to be the case.
Do you think that when the elec fan is running, that that would make the engine fan more noisy because of the additional amount of air being pushed through it by the elec fan?
Thanks again, Pickles.

I dont it would make the engine fan any noisier. I ran mine in the driveway yesterday to watch what the condenser fan was doing. It was actually cycling on/off at fairly short intervals i.e. on for about 3-5secs, off for about 20 secs. This was mainly to do with fairly low ambient temp. and would roughly match the compressor cycling.
You really have to be right in front of the vehicle to hear the fan. Unless you have bionic hearing of some sort!

Conversation went off on a tangent after I suggested Pickles invest in a Ultra Gauge...

I know you like the "factory look" with no extras, but as I mentioned before it can be mounted very discreetly and removed in a few seconds. Certainly gives you piece of mind about a number of critical indicators (including engine temperature) that the original Defender gauges are a bit slow in picking up.

Cheers,

Lou

I forgot to add, that, as the aircon condenser is dumping extra heat into the airflow coming through to the viscous fan clutch, it would cause the clutch to lock up sooner and stay engaged for longer...so yes, having the aircon running would make the engine fan seem more noisy because you would hear it working more often.
But its due to the extra heat, not the extra airflow.
