"I own a small business (for 42) years for which we own numerous (not counting the little stuff like chain saws and whackers) pieces of equipment (24 engines from a lowly 6 cyl. Nissan to a behemoth 631 B Cat. scraper). We live 125 miles from civilzation meaning we don t just hop in a rig and go buy a bolt. We do have a NAPA store which seems to think I like to swap parts out on an annual basis.I ve decided to try purchasing parts here online to see if they hold up any better. This thermostat goes in an old Ford F-250 and it is the 4th. thermostat in 4 years (normal for NAPA so far). I spent about double for the part but hope it holds up for 5-10 years. Only time will tell." posted by: Old Dude on February 8, 2014
