"When I was looking for a rubber parking brake cover to put on my 84 Monte Carlo I was about to give up in finding one. Then I went to APW and found the cover that fit exactly. It isn t always easy to find the parts that fit on a 30 year old car." posted by: nick on November 4, 2014

"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

"I purchased this thermostat when I had my head gasket replaced. I needed a 185 degree thermostat. I have had some problems in the past with other cheaper thermostats so I decided to spend some extra cash and purchase the Jet thermostat. When it arrived I was impressed with the overall appearance it was highly polished and just looked awesome. It runs at 185 degrees just as described and has performed great. I m not sure if its worth the extra money but I am very satisfied with its performance." posted by: KahonasGrande on May 10, 2014
