Cylinder Head Warranty

All of Hugo Auto & Truck Parts cylinder heads are warranted against defective materials and workmanship for a period of 90 days.

All of our heads are equipped with a HEAT TAB to detect abnormally high temperatures. A special eutectic metal (heat sensitive) has been formed into the center of the tab. When the head reaches 250°F the center of the heat tab will melt and flow out. This is a positive method of determining whether the rebuilt head has been overheated beyond normal operating temperature, thus voiding the warranty.
