Radiator system


1. Glazing. A belt with slick, hard sides may slip and cause over-heating.

2. Cracks on the other side enlarge as the belt flexes around pulleys can cause the belt break at any time.

3. Peeling on the underside gives uneven surfaces which cause the belt to run rough and fail.

4. Softening. A grease softened will rot and fail.

5. Splitting. Belt may look good from the top but the sides or the bottom can be split and worn to the point of failure.


1. Hardening. A hardened hose transmit shock to the radiator and the hose can fail without warning.

2. Swelling. An oil-soaked hose will swell or have spongy ends which indicates oil or grease damage.

3. Worn clamps. Replaced clamps that can’t be properly tightened. Always replace clamps when installing a new hose.

4. Cracks or Breaks cause leaks that can’t be stopped by tightening clamps.

5. Bulging. An excessive bulge under pressure may be caused by deterioration of yarn reinforcement
