Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2003 Toyota Tacoma Owner Comments

Leaky water pump discovered upon routine change of timing belt on 2003 Toyota Tacoma 2wd prerunner. Discovered complete lack of gasket and woefully inadequate amount of sealant apparently applied at factory. (no more than 1/8" wide after compression between water pump housing and engine block) engine continually used a small amount of coolant/antifreeze and over time had built up a substantial volume of sludge/crusty coolant around water pump housing and timing belt (crankshaft) pulley. Although absent in this instance, this build-up has the potential to break loose and fall between the timing belt and pulley and ultimately cause timing belt breakage. Replaced belt and water pump. Re-manufactured water pump is equipped with a gasket.
