Can you explain a little further the "Clockspring" electrical connection.

Think retracting extension cord.

I stopped using Bellevue Lexus for oil changes in my '92 LS because I once got it back with the new oil added on top of the old and no filter change. Its NEVER been back.
 
A friend with a PRISTINE garage floor got his '95 LS back from the same dealer with a leaking rear engine seal after an oil/filter change. $1100 later and all they would do was offer a free oil change.

I understand 'retracking extension cord' but I would like to understand:
 
1) What the clockspring does?
2) How does it work?
3) What is its purpose, as it relates to the SRS system, or any other system?
 
Any hints.....

I've done this on several cars/trucks and am about to replace timing belt on our 05 highlander with 101K. It's a good idea when replacing the timing belt to also replace the water pump and other belts if applicable along with applicable tensioner pulleys. Usually at least with our Hondas you can buy a kit that comes with the timing belt, pulleys etc. Water pump is extra. expect to spend anywhere from 600-1K depending on what all you're replacing and your shops rates. Many of the parts are cheap, it's the labor that is expensive, so keep that in mind.

This "clockspring" is a ribbon of wires connecting a fixed electrical point(s) on one end to a rotating electrical contact(s) on the opposite end. The ribbon is wrapped around the stearing shaft several times to allow enough "play" in the moving end.

Okay, So if the connection at any point is "loose" it could cause the warning message. Am I correct in that? The fact that it does not happen all the time would fit in this case.
 
In your experience is there another possible source of the intermittent message.
 
Also, if the message comes up should it leave a code in the diagnostic computer.
In what cases would a code not be saved?
The message is "Check SRS Airbag System Have your vehicle checked by a dealer immediately"

Re: Difficulty of timing belt change? 2004 Highlander V6 [mpolan] by mckeown

My wife also has an 04 V6 AWD. I did the timing belt a few months ago.
 
Regarding that aluminum engine mounting bracket right on top of the water pump, I removed the single bolt along the frame right in front of it holding a PS hose to the frame. After removing that, the bracket just slides off. No removing the studs nor jacking up the motor.
 
A few things make this difficult .....
no room to work. My hands were sore, scraped and cut for days.
The alternator bolts were VERY difficult to get to even for normal belt replacement
After removing the bolts, getting the upper belt cover out/ back in properly was difficult.
Glad I still have an electric impact wrench. rated at 340 ft lbs. Still had to stay on the crank bolt for about 5 minutes before it would budge. I don't know HOW I would have removed it if I didn't have an impact wrench.
 
As already stated, not a job for the feign of heart. Too easy to strip a bolt head of worse if one is not careful.

Well, I just heard from the mechanic. my '02 HL had an oil pan leak and a water leak as well as the main engine seal leak. He also said my engine had a lot of "gunk" in it as well. He says that Toyota has had some problems with that V6 engine (same on as Camry?).
 
What irks me is that I've changed the oil every 3,000 miles, first with the dealer and then with Jiffy Lube. I had everything done that was "recommended", as I had decided it was better to play it safe. Now I find it was all for nothing (well, I guess it could always be worse) since I still will have to pay what I'm sure will be upward of $2,000.
 
Of course, I have to take the mechanic's word for it. Unless I take the engine apart for myself and have a look (which is outside of my capabilities), I'll never know for sure.

The problem is the TYPE of engine oil that was used. If you want to keep the GUNK out of your engine, you need to use a top quality full synthetic motor oil, such as Mobil One or Valvoline or other top graded oil, AND a top quality synthetic motor oil filter, such as Mobil One or the Purolator Pure One.
 
My 04 V6 FWD HL has over 110,000 GUNK free miles on it, and I only change oil and filter every 7,500 miles using either Mobile One or Valvoline full synthetic motor oils and Pure One motor oil filter. It always runs like brand new and doesn't leak a drop of anything.
 
Also important to remember: Every 60,000 miles to Flush and change the Automatic Transmission fluid and to Flush and change the Brake Fluid. This will keep the GUNK out of these systems also.
