There are two distinctively different types of belt noise, “Chirp” and “Squeal”. Each has its own unique characteristics, causes and solutions. One method to determine if the noise is a chirp or squeal is to use a water squirt bottle and spray the rib side of the belt while the vehicle is running. If the noise gets louder, it’s a squeal. If the noise goes away, it’s a chirp. “Chirp” is a sharp, high-pitched, repetitive noise of short duration, usually worse at low engine speeds (idle). As belt speed increases, the belt noise may blend into one audible noise, but most likely diminish in intensity such that it won’t be detected. Most chirp noises occur as a short belt span enters into a grooved pulley, typically after exiting a backside pulley.

Warning: Any existing misalignment condition probably caused pre-mature wear of the belt ribs on the old belt. A new belt is recommended once the accessory drive has been realigned. “Squeal” is a high pitched noise, typically lasting several seconds in duration. This type of noise will typically increase in volume as the engine speed increases, and is caused by relative slip between the belt and pulleys.Users active in the Volvo Forums DIYs in the Volvo Repair DatabaseA/C clutch shim procedure for S60I’ve confirmed that my AC clutch is not engaging properly and that it could be because of wear to the clutch plate . how to charge an ac unit with r22I’ve read several posts about shimming the clutch plate so that the gap is return to within spec. daikin inverter ac unitsI’ve seen instructions posted for other Volvo’s but not for the S60. through the wall air conditioning units 18 000 btu

Does someone have instructions on how to do this for the S60, or at least instructions on how to remove the AC clutch pulley.Here’s the now famous DIY procedure to fix your air conditioning with a AC clutch shim, but for the Volvo S60. If your AC blows cold for only 5 minutes, and you’ve recharged the R134a, this may be what you need to do.AC clutch shim procedure for S60    The following images are from Volvo and describe replacing the magnetic clutch compressor.AC clutch shim procedure for S60 All MVS email complies with the CAN-SPAM Act.

Freon will need to be added by someone. : Adding freon or topping off a cars A/C system is the most common task performed to restore performance and get cold air blowing again. However, adding refrigerant isn’t always the solution for car air conditioning problems – troubleshooting may be required before just charging a car AC system.

There can be many other things wrong besides a system being low on refrigerant. To diagnose/troubleshoot problems, an A/C manifold gauge set is needed to read high and low side pressure readings. Avoid adding refrigerant with a simple charging kit like the ones sold at parts stores. Don’t add any stop leak, this can cause problems in the compressor, expansion valve or condenser. The image above was taken at Moog and US Hwy 19 in Tarpon Springs Florida, it made me laugh. The sign says “Your wife is hot! She wants her A/C fixed, let us check it for free”. For some help taking care of your AC problems yourself continue reading. This is where it starts to get serious. Keep in mind that using an A/C gauge set and seeing BOTH high and low side readings can help in diagnosing the problem when you know what to look for. First, on a 134A system the high and low side service ports are different sizes. AC gauge sets have color coded hoses, the blue color coded hose has a connection that fits on the low side service port and the red hose has a connection that will only fit onto the high side.

The yellow hose won’t hook up to anything if just checking the readings; it can be used to connect to a vacuum pump or attached to a refrigerant can or tank. *Make sure the condenser fan comes on when the readings are being checked. Below are normal car AC pressure readings with 134A. * Normal readings on high and low side with AC OFF (static pressure) – Depends on outside temperature, but normally is between 80-105 PSI * Normal low side reading with AC on high-speed and MAX & engine at 800-1000 RPM’s – Ranges from 25-35 PSI – Note that on many Chrysler products a normal reading on the low side may be 15-25 PSI * Normal high side reading ranges from 200-350 PSI Don’t assume that if adding little Freon is good that adding allot is better! Overcharging just a little can decrease the performance of the system and possibly damage the compressor. Additional Car A/C Info – Troubleshooting Gauge Readings With the AC on the coldest setting, use a thermometer in a middle vent.

Normal vent temperature readings will vary depending on the (ambient) outside temp. The vent temperature should range from around 42-55 degrees in my experience. If normal gauge readings are obtained and the vent air is cold – STOP don’t overcharge the system. The only proper way to remove refrigerant is with a AC recovery machine so if this is being done at home I can’t emphasize enough NOT to over-charge the system. And actually the best way to insure the proper charge is in a system, is to use an AC machine to recover the freon and then evacuate and recharge the system with the correct amount. Most cars have the factory specified amount on a decal under the hood. See the next page for gauge readings and images. Continued on Page 2 It looks like you're new here.

So I left and just figured that maybe it's just the harsh weather up here in northern Minnesota. (was hardly ever above 10 degrees when the 'whine' noise started) Then a few weeks ago, once it started getting to be 20 above all day, the whining noise suddenly stopped! I couldn't believe it and figured maybe it was just a lucky day for me.. but for the last 3 weeks, my Jeep hasn't whined once!!
