Volvo Tech Tip: Exhaust System Squealing Noise

When certain Volvos are driven through puddles of water, slush or snow, the exhaust may cool down fast enough to change shape and touch the propeller shaft, causing a high-pitched squealing noise. This noise will be noticed by the driver for only a short time, and once the exhaust temperature equalizes, the noise will disappear. A telltale mark will be left on ....

When certain Volvos are driven through puddles of water, slush or snow, the exhaust may cool down fast enough to change shape and touch the propeller shaft, causing a high-pitched squealing noise. This noise will be noticed by the driver for only a short time, and once the exhaust temperature equalizes, the noise will disappear. A telltale mark will be left on the propeller shaft. Should a customer with a 2001-on AWD model (S60/V70/XC70/S80/XC90) experience this condition, install an exhaust support kit.

Service Procedure:
1. Remove the existing cross-member and install the new one.
2. Tighten the bolts to 25 Nm (18 ft./lbs.).
3. Install the clamp on the exhaust pipe with the screw hand-tight.
4. Install the rubber blocks and adjust the clamp so that the rubber blocks are vertical.
5. Tighten the bolts to 25 Nm (18 ft./lbs.).
