Tried to replace my leaky radiator this weekend with a used one I picked up (said he pressure tested it), figured might as well do the tstats and updated upper rad hose while I was at it. Took me a bit to get down to the tstats but eventually got them replaced and before putting the new radiator in decided to fill it with water.. turns end tanks on the new rad leaked more than the one I just took out..
Ended up reinstalling the original radiator since it was 1am on a Sunday and needed the truck ready Monday. Got it all back together, did a flush with vc then 2 flushes of water (heating it up to 190 w/ heater max hot between flushes and draining using driver side engine block and rad plugs to drain), then filled it up with some simple green and another 2 flushes of normal water, then 2 flushes of distilled water, then 4 gal of premium gold and topped off with distilled. Took forever.
After spending all night on that fun project I did a quick oil change w/ rotella T6 in the morning, first oil change since I got the truck and was pretty simple.
Took the truck out on the highway for it's first drive and noticed the eot/ect were higher than normal (199-204). Before all of this the temps always sat around 190 for normal cruising no load so I'm just wondering what the deal is. Fluids were all good and it's only about 50 out.
Any ideas or is this something with the new tstats?
