Hi all, my beloved "sharky" has had airco problems for quite some time. The coolant simply "disappears" over the period of weeks / months. I followed the recommendations to keep the airco running on each ride, although the cooling only works when the thermostat hits a certain temperature.

Last summer I had it filled 3 times, each time was completely empty (675 gr), the dealer tested the airco system under high pressure and with a tracer - but found no leakage.

Now that spring is at the doorway - I'm facing the same thing again.... I must add that I use the car only 2-3 times a week, because I drive a work car daily as well.

Has any of you had a similar problem ? did you get it fixed ? what was the cause ?

I'd be grateful for any info !!

 

Obviously it's leaking out fast someplace. Another fine job by the knowledgeable Hyundai tech. I wonder how much you had to pay for that boondoggle.

Most of the time the seals go bad in the compressor, as this is the only moving part. However, the leak can be anywhere. Could be a hose coupling, or even a hole in the exchanger.


I never used it, but don't they have that leak detector stuff, like at Walmart? It's really easy to put in coolant these days. You just have to find the low pressure coupling of the system, it's usually easy to get to. The can of refrigerant comes with the adapter, and even a pressure gauge. You just put in the can of refrigerant w/ leak detector, run it, and look for the dye where it comes out.
