Mondial A/C Question

Where are the a/c charging ports and how do you gain access?
Thanks in advance

 

If it is a Mondial t they are located under the right rear by the compressor.

 

Sorry to steal the thread but since its hot and I have been using my a/c alot more in my mondial 3.2, I noticed that my a/c compressor makes a lot of clicking noises when on. Is this normal or do I need to lubricate something? I do know that it was converted to 134. It stays cools so thats not an issue. Its just noisy and want to be sure its OK.
Thanks in advance,
Nathan

 

I have an older Mondial-8 and the A/C charging fittings on mine are on the top of the compressor on the right front side of the engine. The rear-ward fitting is the low-pressure inlet to the compressor where the refrigerant goes in when recharging the system. Mine is an older R-12 system, though. I just recharged it two weeks ago, but the system has a lot of moisture in it and needs the dryer replaced.

Anyone have an idea what the noise is?

 

It may be the compressor cycling on & off... That can make a "click" like sound.

If that is the case, then it is either working correctly (depending on how often it cycles), or it is low on refrigerant.

 

Put a test light or voltmeter on the power connection to the clutch to verify that it's the noise source. If the power is going on & off with the clicks, then you've found it.

The wire is usually routed from near the dipstick over to the compressor.
There's a plastic covered spade connector on the engine end of the clutch wire that you can make a male-female extension that lets you get to the wire.

If the engine is idling & the A/C temp & blowers are both on max, the clutch should stay engaged continuously, or at least for minuites at a time.

If you're marginal on refrigerant, it'll click on & off several times/minuite.

 

but should it be that noisy?

 

I looked in my mondial's manual and on page 19 it shows that there is a place to lubricate the compressor on the top of it. Also, I cant seem to find the low end of the a/c lines to check the coolant level/pressure. Where the heck is it?!!!!
Thanks,

Okay,

From UNDER the car. Find the A/C compressor located at the front passenger side of the engine. Follow the A/C lines from the compressor towards the passenger rear wheel. Less than a foot from the compressor will be a low pressure hose with a nipple pointing downward. A black cap should be on the nipple.

This is all kinda tucked up within the chassis, and can only be seen from UNDER the car.

 

Ahhh. I should have known/seen this when I was changing out the accessory belts..... Of course Ferrari wouldn't make it easy!
Thanks,

Thanks Javelin you were right on.
Got to work on Mondial for a client last week / port are as you discribe
Had to crawl over the top of the motor to reach them.
Anyone interested in converting over to 134 need to remember that the charge ports are close together to we were unable to use the normal a/c adapter for charging / we used a hose off a quick charge setup you buy at you local parts store. You can't put both high and low adapter on at the same time either.

The system charge and cooling worked fine. We found a leaking pressure switch on the receiver dryer so that is on order.

We also need to locate the reason why you have to drive over a bump to get the blower to turn on....good thing we had a sense of humor fixing this one.

 

I did a search but could not find what AGIP TER 60 oil is. Thats what my manual says on page 19 to put into the a/c compressor..... Any Ideas?

 

Did anyone ever find an answer as to what AGIP TER 60 can be substituted with OR where to get it?

 

I have never heard one of these comps, but do you remember if this , in the past, made LESS noise? That would be key in indicating if your comp is on its way out (if before, it operated with "less" noise that now). Increase growling/grinding is not a good sign, man. Yes, it may still cool, but it may last even up to well, a few months more, Ive seen them. Then, of course, they will quit. then, you will have to redo all of the system, cond, TXV, comp, dryer, maybe even e new evap, if you have to yank it. Older models used copper which last forever.

If youre lucky, they will quit with clutch not locked up, as the belt may burn up/lock up other accessories. just keep a close eye on it.
