For about Half Price of Local Parts store, got a QUALITY, properly functioning, Radiator cap. These sucker's are not MADE IN CHINA GARBAGE.....MADE IN INDIA. HAVE ALWAYS INDIAN CRAFTWORK, PEIDE IN THEIR WIRJ, AND QUALITY OF THEIR WORK 50 TIMES BETTER THAN 'SLAVE LABOUR CHINA WORK'! AS soon as changed out my 12 year old Rad Cap....for this one...NIGHT & DAY DIFFERENCE! IT IS ON A 96' CHEVY SILVERADO....BUT NOW...TRUCK HEATS UP FASTER, DEFROSTS QUICKER...VERY IMPRESSED WITH QUALITY, PERFORMANCE AND PRICE! EXCELLENT PRODUCT....WELL WORTH YOUR HARD EARNED MONEY!
