Fixing High Coolant Temps

*Did our video help you? If so, consider buying us a beer: https://bit.ly/3feE6tJ* In this video we discuss the causes of why you'd see higher than normal coolant temps and how you'd address them. We replace the radiator and fan clutch but don't actually show it because I cover those repairs in these videos: Fan Clutch Replacement: https://youtu.be/WzhlACxqeqQ Radiator Replacement: https://youtu.be/2nVbwe2t2T8 In the order of least to most expensive, and sort of easiest to hardest to address, I'd check the following: 1) Coolant Level - is it full? 2) Radiator Cap - is it intact and holding pressure? 3) Thermostat - what position is the jiggle valve in? Should be at 6. 4) Fan Clutch - test and replace if it shows signs of wearing out 5) Radiator - it could be clogged and not allowing sufficient coolant to flow. If you've gotten this far and still have higher temps, replace it. If you're interested in buying an OBDII reader that works with Android devices, here's what I got: https://amzn.to/2BeQUsM And, if you go the Bluetooth reader route, buy this as well. It allows you to turn off the power to your reader so you don't have to pull it out every time. The reader constantly draws a small amount of power and could drain your battery if your truck sits for a long time. https://amzn.to/2WDL4dl **As Ebay Partner Network members, we earn commissions from qualifying purchases. **As Amazon Associates we earn from qualifying purchases.
