OK...here it goes: I have a 1989 renix that pretty much has nothing old left on it. 6" lift with 35's and about 1000lbs over stock. engine is 4.0 with comp cam and polished and ported head, bored out throttle body, spacer, headers, and a high flow intake...blah blah blah... I know, but in troubleshooting my nightmare, this may come into play. so...cooling system mods: 3 row aluminum radiator, lower hose accordion style with spring. upper stock hose type. Flowkooler water pump and a flowkooler high flow thermostat hsg. 3 10" elect. fans, and a mr gasket type performance thermostat. there is the oem ac rad and a small oil cooler rad installed. I have also installed a
trans aluminum heat sink type cooler to disperse even more heat from the engine radiator. now under normal driving conditions, freeway city streets altitude, and offroading the system is perfect. It will
run at 195 to 210f. but when I need to climb on a load up to the mountains on a highway, it creeps up to 240 easy, and I have to pull over letting it run in park, cool off and try again. So if anyone out there has a clue, please help! Everything in the updated "open type" cooling system is new. oh and I ran thee head gasket test, and checked the manifold and the header and no leaks. all of my vacuum lines are new. all sensors are new. motor has 54K on it. Thank you for your time....
