Some 1988 C/K trucks with the 5.0L or 5.7L engine may experience a condition where the lower radiator hose interferes with the frame strut rod and
chafes the hose, which could result in a coolant leak. If this condition is encountered, it can be repaired by replacing the lower radiator hose with a new
design hose, which contains an additional hose protector (See Figure No. 1).
This condition was corrected in production effective with the following VIN break points:
