328 air conditioning query

You mean it doesn't get cool? or it doesn't even blow any air?

 

burnt out fuse box

 

they are weak as pi55 even when in tip top cond. , mine has a temp of 7c coming out of the vent after 10 mins IN THE SHADE but will never cool the car if the sun is out

Someday someone will make a unit that fits nicely into the older cars and we can use the cars more often in the heat.

But like pap said, is it flow or temp related ?

 

just fit a late model Japanese compresor,guy in Melbourne does it

 

thanks for the advise POP

 

one out of a Magna ?

they're the best I've seen

 

unsure what out of.lambo guy down here does it forgot his name.Gee my old crate gets hot.

 

which old crate ?

 

The one you can blow through

i can't see why a compresor would fix the problem. it really needs all new lines and tx valve to work at capacity with the new gas. it could do with a larger evap too...but that might be pushing things.

make sure the fresh air is CLOSED and open the vents on the dash. that helps a heap. i might just be stating the obvious, though.

JM...have you learnt how to turn off your heating yet?

 

I'm getting Marc to disconnect the damn thing, as if I'll ever need a heater in Qld

better not let Horse know though as he will deduct another 100 points next concourse ....shhh

 

The system should be pressure tested for leaks and any leaks should be repaired.If you want to upgrade then a bigger evaporator (if you can get one to fit) a bigger condenser and make sure that the condenser fans are working as well.I would see if you could find some one that has R12 and put it in there as the efficiency of R134a isn't as good but as I said make sure there aren't any leaks otherwise you just be throwing money away.Some people have replaced the aspera compressor with a sanden compressor,but I think the other draw back in these cars is the air circulation

 

what would you know about aircon?

 

OK... here we go.. once again, Aussie 328 lose out on spec here... very late UK QV's and all 328 in UK have the rotary type compressor... which provides constant pressure rather than the pulse from a reciprocating piston in the york type...

But the Aussie 328's I've seen all have Yorks... which as said, are not great.

Changing to a rotary compressor here is a good idea... they're much better.

But you also need to be sure that the rest of the system is in good order... If you've changed to 134a over R12 you really must change all the hoses too....

The hoses for R12 are less resistant to 134 weepage.. (molecule size as I understand it)... also the oil for R12 does not carry 134 properly.. so a full system re-birth including all new hoses is the only sure way of getting an effiicent system... which is cost prohibitive in my experience...

So it would seem that unless you can find an R12 source (very hard, possibly illegal) your 328 system is doomed to a life of mediocrity unless you invest heavily in it.

If everything is in perfect working order, a 328 AC system is quite adequate on 134a... but it seems most owners prefer not to fully upgrade.

I don't blame them either.. I wouldn't be prepared to offer an estimate.. it's one of those jobs that just takes the time it takes.

Hoses can be made locally, and rotary compressor is easy... Ferrari list the correct brackets to do a nice job of installation... but again.. price/availability prohibitive... so custom brackets are the go....

 

Slightly off topic but seeing all the ac gurus are kindly offering advice...

Having probs with my cellar ac drying the air out too much. I thought it may have been related to the thermostat and had it changed but it hasn't helped.
Then again, it could be a bad batch of thermostats.

Any ideas?

Free flagon of rough red for information leading to a succesful prostitution.

 

don't wine cellars need proper humidity control... not just AC?

maybe add a humidifier before all your corks shrivel up...

 

According to the literature, it has humidity control built in but it is managed via some tweek in the thermostat and hence why I think that may be the prob. if I can't sort it out, will have to get a humidifier....there's only one worst thing than a shrivelled up cork....

 

yeah... a bunch of blokes that know your wine is going off and you need help drinking it!

 

Nah, it's around 60% humidity....would prefer it at 70% but it ain't panic stations yet...

 

course it is.....

Rally Tas soon... place'll be invaded.. plenty of help with clearing it out..

 

red mist...

 

Wrong end of the island and I'm going to be up there with the cellar locked at this end. That doesn't mean we can't share a bottle or 2 if anyone is heading south after the rally.

 

Steve there are various ways of controlling humidity from slowing the evaporator fan speed down to having a coil with wider fins or if it has a inverter compressor then it can slow the compressor down so that the evaporator temp is higher and doesn't condense the moisture in the air.I dont know how your system is set up but if it has a humidistat in it then it will probably just slow the fan speed down.If it still gets to dry then the cheap way to do it is to run a kettle off a timer but you will have to keep checking the water level and keep topping it up.There are other ways but are a bit more complicated to explain
