I removed mine last August and in September drove from Miami to Baltimore in two days with the inside of the truck fully loaded, the back end was sagging. 70-80mph the whole way with the temp needle right in the middle. Removing the oil lines was no more difficult than replacing the oil filter. 15-30 minute job. Take it off and try it. If you think it runs hotter get the lines fixed at a hydraulic shop and put them back on.
