Overheating 1997 850 wagon

I actually broke down several years ago and bought this set of Torx sockets (I should add that I'm a professional aircraft mechanic and "needed it for work"

)

Admittedly, at $75, it's a "Cad-e-lack" solution, but it's a decent quality assortment, and the 1/4" drive stuff fits into my existing 1/4" Snap-on handle.

Tools are an investment for life, I guess.

I'll have to look after I get home from work, but I was under the impression that I needed a long bit to fit between the fuel lines. MIJ's post was talking about a 5 inch bit. If all I need is a socket with extention I'll be good to go. Thanks again.

tcapp, you are correct, the bit itself needs to be long. Just adding an extension doesn't get it...I did that and fubarred my screw heads...had a time getting them out then and then had to replace them (albeit cheap). I found a set of long handled ones...sort of like a screw driver and they interchange into a holder that you use to turn it with- AutoZone, but I know it's not the best one to get. The torx bit must seat squarely (and that's the hard part with those fuel lines in the way) or you'll mess up the screw heads (actually, the rear one...the other one you could use a regular torx socket)...and the size must be exact or same thing happens. Oh, and soaking the heads with BP Blaster a half an hour (or if they're really tight, over night) helps a bunch. Have seen them these bits on line here: http://www.mcmaster.com/

Thanks guys for all the help. I got started a little late today. Temp in Charlotte this morning was in the 20's. Had no luck finding a long torx at sears, harbor freight tool, home depot or lowes. I did find at auto zone an "L" shaped set of torx similar to a set of allen's. They were just long enough to reach and with the help of a closed end wrench on the head I got just enough leverage to break it loose. When I got my temp sending unit at Volvo I tried to buy new torx bolts just in case I dropped one or bummed one up, but they were out of stock. I reused the old ones but someone has been there before and I wish I had new ones in case there is another change. I didn't drain any fluid. I disconected the small hose at the tank and then took the tank off the wall and swung it to the back of the engine lower than the thermostat, clamped the upper hose and went to work. minimum fluid loss.
Looks like its a done deal. I ran the engine up to normal temperture, let the therostat cycle a few times, built up pressure on the system and no leaks. Need to run it aroun town later to be sure, but all looks well.

Thanks again for the help.

Good work!

It was a dead give-away. An engine can not be hot after 6 hours of sitting, so the sensor had to be incorrect.

Great job! Sounds like you found the same set of torx "L shafts" that I found. Not the best but they do work. I still use them to get the spark plug cover off, etc. Good thinking on swinging the over-flow tank to below the thermostat! I like that....now why didn't I think of that?....I syphoned out fluid and had to refill mine.
