Can installing a new temp sending unit change the location of the needle on the temp guage? I changed out my cylinder heads this weekend after I had some bad valve issues, and the shop lost my sending unit. I picked up a new one from Kragen, and now the guage is reading in the middle of the guage, not down on the lower range line like before. It may be psychological, but seeing the guage up there freaks me out.
One note is I switched to larger chamber heads which were supposed to help with a bad pinging problem, and it might be possible that the new heads would make the motor run hotter?
Anyone had this happen before?
