So I have had the truck for about a year and recently after installing a CAI my temp has been a little erratic. Not getting to the overheating point but it will on a regular basis fluxuate from norm operating temp to a little over the half way point, hang there, and go back down. .... at first i was thinking thermostat but now im worried that it is the water pump going bad. Any input is greatly appreciated. Its an 07 5.7 with about 44000mi.
