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 Ford Focus Owner Comments

problem #1

Focus SE 2.0L 4cyclinder

I read a couple other complaints about coolant leaks around the Focus thermostat housing. I've not had a leak there or anywhere else before, but in trying to find the origination, the complaints I've encountered may be helpful. It appears the leak on my 2003 2.0L, DOHC engine maybe at the end of the 'Pipe 1 to thermostat' hose connection at the thermostat, or perhaps the thermostat itself. The complaints I've read so far seem to "focus" (sorry for the pun) on the thermostat housing itself. I know it's more expensive, as a part, than either the hose itself, the thermostat itself, or the thermostat's gasket. I hope that's not what I'll find. It was confirming to read about how difficult it was for the investigator to access the thermostat housing itself... I completely agree that the many hoses, tubes, and other equipment in the area are a nuisance!
