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.

1997 Infiniti QX4 Owner Comments

QX4 V6

  • Automatic transmission
  • 100,100 miles


I have an Infiniti QX4 (1997). Belts, tires & battery aall less than a year old. Due for an inspection & oil change (I do use Royal Purple, though, which I've heard buys a little extra time...). Anyway, it overheated on my way to work last Friday, though I made it to the parking garage. My dad, who races & knows quite a bit about cars, diagnosed the problem as a gash in the upper radiator hose (& also noticed that one of the belts was rubbing right against the hose. All the fluids had leaked out. I got a mobile mechanic to come out and replace the hose & adjust the belt so it would no longer rub against the hose. He repaired it yesterday, & the first time I drove it was home from the office this afternoon (about a 15 min drive w/ the occasional red light). Not sure if this makes a difference with anything, but I stopped for gas on the way home, & due to some technical glitches, the only kind of gas available, was super unleaded. Well, I needed gas very desperately, & got a tankful of this super unleaded at a Valero station. Usually, all I use in reg unlead. Had to blast the heater/windows down, for the last 5 minutes of my journey & needle was pushing the danger zone when I pulled up to my house.

I decided to let it cool down for a little while before a much needed trip to the grocery store. I put water in it, though it really didn't seem to need any, & the needle was almost vertical when I got to the store 5 minutes later. I had read that I shouldn't turn the car off while its overheated, & instead, to put it in park, windows down, heat & fan on full blast until the needle calms back down, which it did after about 5 minutes or so in park.

HOWEVER, I got about one minute away from my house w/ a truck-full of groceries, when it slowly, and then very quickly, overheated (needle in the danger zone & the smell of an engine starting to burn up on me), and I pulled over. The liquid dripping (or rather streaming) from my engine, was steaming as it hit the cooler ground & appeared to be a slightly green tint--and there was a lot of it!

I'm very badly broke right right now (though if you know what's wrong & how much it will probably cost me, please don't sugarcoat it...), so, any info, advice, tips (I'm pretty damn mechanically inclined "for a girl"....

Will I have to suck it up & pay for a tow, or, if I fill it up real quick, could I get one minute down the road to the gas station, at least???

Thanks in advance!!
