Hose Clamp Usage Chart
Spring type hose clamps are used in all applications. If replacement is necessary, replace with the original Mopar (R) equipment, spring type clamp. To identify size of spring hose clamps, the size in millimeters has been stamped on each clamp. Refer to Hose Clamp Usage Chart for proper size and location of hose clamps.
CAUTION: Use of general purpose pliers can bend the clamps to an out-of-round condition. Resulting in a loss of clamping strength.
