[QUOTE="machoheadgames, post: 428015, member: 18789"] No, nothing special about a 4.2. Very basic cooling system. Possibilities are that wrong coolant was mixed and caused sludge, improper direction water pump was installed and didn’t pump water correctly, system was driven immediately after being worked on and didn’t have time to bleed itself, etc. No telling what exactly happened but they aren’t a flawed design and in good condition, have no inherent issues. Also nothing wrong with a “plastic” radiator. Like metal, there are many types of plastic. Radiators are made of a special type of composite meant to last in the application. Hell, most YJ and TJ radiators last at least 10 years, if not 15, 20, or even more. My OE radiator went to 22 years and it wasn’t the composite that failed. [/QUOTE]
