coolant problems
I've been having some problems with my truck running about 10 to 15 degrees hotter at highway speeds. Also when I accelerate past 70 or so my temp gauge will rise with my speedometer??? I took it in and the shop said I needed a new radiator, so they replaced it. Problem is it is still doing it! What could it be? Thanks
05 Cummins, 160k, just exhaust and CAI for right now |
I would be replacing the thermostat, followed by the water pump...and I would inspect (read: give it a squeeze) the lower radiator hose to see if it still has the internal support spring/wire (to keep it from sucking shut).
I would also consider checking the sending unit for the gauge...at least verify the gauge is reading correctly. |
Thanks so much for the help, also. Where is the sending unit and how do I check it?
