thanks for the help. youre right it does not overheat as fast over 60. it runs high real fast when on heavy traffic. i will try to replace the fan clutch. how do you troubleshoot it thanks a lot. *cbhvac* stephen@screweduponpurpose@carolinabreezehvac.com wrote in i just changed it recently. first you need to determine if its really overheating. if it is then you have already answered your own question. probably wont overheat as fast on the hiway at speeds over 60 will it considering the fact that anything said on usenet about things we cant see and diagnose ourselves given the consideration that you have a new rad in there then look at the facts....it overheats with the air on....your condensor is adding a few btus to the rad and the fan isnt able to pull air through it fast enough to remove it. check the condensor fins to make sure they are not clogged with road debis and if not chances are that you are going to find out that your fan clutch is toast. i have a 1992 dodge dakota. i noticed last summer that it overheats. it did not overheat during winter. i noticed just recently that the temperature rises almost to overheating when i have the air conditioner on. it has a 5.2l engine with a fan clutch type cooling fan. thanks for any help. have you ever changed out your radiator it may be beyond its usefull life. test it out and change it if necessary. -- fmb only one b in fmb .

thanks for the help. youre right it does not overheat as fast over 60. it runs high real fast when on heavy traffic. i will try to replace the fan clutch. how do you troubleshoot it thanks a lot. run the truck till it gets real hot pull over and turn it off. with a gloved hand hold a fan blade with the flat of your fingers on the flat of the blade dont grab or grip it and have someone else start the engine. the fan will want to go around whether the clutch is good or not. if the clutch is good you wont be able to hold it so watch it so you dont get your fingers slapped too much. if the clutch is bad the fan will just push on your fingers a bit like its trying to turn but it dont take much effort to keep it still. it might take a few trys to do this as when the op turns over the engine the natural response is to jerk your hand out. you can also use a paint stir stick to hold the fan but ya gotta be smart enough to not let the fan eat the stick and toss pieces into your eye. or you can just replace the fan clutch. you can find one on-line for $60-80. try rockauto.com -- fmb only one b in fmb .
