IMHO, car manufacturers sometimes get carried away with their testing procedures and expensive tools. Unless you're curious, I don't think I would spend the time and money diagnosing a component that frequently wears out, that can be replaced in half an hour or less in many instances, and that can ...

FAN CLUTCH TEST (MINIMUM SPEED REQUIREMENT) 1. Use twink to mark the fan pulley 2. Turn AC off 3. Start engine & run it @ 2000rpm for 5 minutes 4. Aim laser photo tachometer @ marked fan pulley. Increase engine rpm to 3500 5. With engine @ 3500rpm & using tachometer, record fan speed 6. If f...

I managed to find an official test procedure from a Ford manual. A laser photo-tachometer is needed & you have to measure the rpm’s at different engine temperatures & rpm ranges. There’s a minimum & maximum RPM specification. I’ll try & upload it to this thread for anyone who needs t...

Car is R134a. Confirmed on Autodata service/repair system. Also I think the R1234YF service ports aren't compatible with the R134A gauges?? First 2 times car was brought in to have AC checked: 1. Viscous fan did not free wheel first thing in the morning when engine was cold & off. There was a lo...

It's an Australian import, second hand & only has 65,000km = 40300 miles !! I don't think it has been into a crash repair shop, at least it doesn't look that way. Flap doors/motors confirmed as there are existing error codes for 3 of the flap motors & sensors. AC has already been recovered, ...

Haha oh the scan tool gave pressure readings in kPA & not psi... Pressure readings (Greek to English): Initial high side pressure after car has been sitting in sun & AC first turned on 413-429 psi -> warm vent air High side pressure after car is driven for 5 minutes 355-369 psi -> cold vent ...

Update: Got the car back in last month & recovered & recharged the system with correct quantity as per Autodata - there is no AC gas charge sticker under the engine bonnet. Also did a few Google searches there is only a 10-20g variation between specifications. The car has come back in today ...

I went looking for some AC pressure, component temp chart(s) for diagnostics & came across Nissens. Looks pretty good to someone like me who has just started in Auto AC as it answers questions (like pressure & temp ranges) that only someone with experience would know. Interested to see what ...

In the end the owner of the car requested their car for use over the weekend. I'm going to get it back from them & then I'll recover & recharge to spec. All I could really do was connect the gauges & release a little bit of gas which took the high side pressure from 300psi to 280psi (car...

Noted. I do have a digital thermometer but was in a hurry to get on the road so I skipped vent temp measurements. Yes I removed the heater core hoses & joined them: 1. Both passenger & driver side vents now read 6C @ idle but low & high side @ 50psi & 350psi (too high) 2. Took the ca...
