A/C blinking light - over-pressurized? Bad ground?

I wouldn't want to bend a pressurized line, knowing if you do damage or weaken it or cause a leak, you're in for several hundred dollars for a vacuum, line replace, and recharge.

 

Just for the screw.

Engineer (pz-60)/ vamplier (7.5") also make a needle nose that may get in easier. They're the same company, just US based warranty for vampliers.


These are all screw extraction pliers.

 

yeah, I hear ya. I tried to gently nudge it over a bit and its not as soft as I thought. :/ need to either grind down a wrench to fit in there or figure another way

 

I can't recall anyone ever saying that thing was suck a problem, so I'm baffled you're having this much issue. Makes me wonder if you're doing something wrong?

I'd be consultiing the factory service manual, which can be downloaded all over the internet (including a sticky thread on this site), or at least checking YouTube.

 

yeah, def watching several different videos on the timing belt process on YT and this bolt needs to come out for the AC compressor to swivel slightly to get the fan bracket out. One guy mentions this because unless you want to evacuate the AC lines and remove the pipe in the way, you have to deal with this bolt in small area to work on it.

Its annoying how such a straight forward process like this can be much more difficult when a bolt decides to be stubborn. I'm going to try grinding a little bit off my cheap HF 12mm wrench so I can get the box end on it. The open end has too much slop and I don't want to round it any more. If that doesn't work I will buy higher quality wrench that might do it before going to vice grips. Yes, I have been tapping with a chisel and using penetrating spray on it too.

 

Made good progress today. I used an angle grinder to thin out my 12 mm wrench to break loose some bolts I was having trouble with. I got the other AC compressor bolts loose also and was finally able to get the fan bracket off. Now I'm studying YouTube videos to better understand the timing belt pulley position before I remove that. Unfortunately the videos I'm watching that you guys recommend are not consistent on where I need to put the pulley marks.

 

There’s a timing belt sticky thread with lots of videos but I think this website has just about the best explanation I’ve ever seen: https://www.toyoheadquarters.com/threads/toyota-2uz-fe-timing-belt-marks-4-7l.335/

 

Thanks @shifty` I will take a look

 

I'm over the hump on this and very glad I'm learning to do it. I had to order the tool so that I can properly torque the crank pulley bolt but other than that things are going good and I should finish up in a couple more hours of work. I really like how they put the marks on the timing belt so that you ensure the timing is not messed up when you reinstall.

 

It’s called a Poka-yoke: https://en.wikipedia.org/wiki/Poka-yoke

And based on your comment, it’s working EXACTLY as designed.

The Japanese are generally brilliant engineers.

 

When I lived in Japan we joked that they were Germans on steroids.

 

I don't see nearly as many cases of 'engineering-in job security' in Japanese cars as I've found in German cars.

A lot of designs on German cars I've owned have left me scratching my head, like, "Who in the hell thought this was a good idea? Guess they designed it after ein Maß too many in Der Englischer Garten..."

When you need to replace oil seals to swap out an alternator, and the job takes 5 hours instead of 15 minutes, that's a problem.

 

During disassembly, there is a nut I misplaced on a bracket under the AC compressor. I'm not having much luck on the Toyota parts diagrams. If anyone can suggest a better way to find this let me know. I think its a M12 nut. Red arrow pointing at the item I'm looking for. @shifty`

 

here's a pic of just the bracket, but can't find the nut. I guess I could call a Toyota parts place and give them this part number and see if they can find the nut?

 

nevermind. I guess all parts websites are not created equal. see below

 

That's why I typically use the EPC site in the parts-finder sticky to hunt: https://www.tundras.com/threads/howto-use-the-toyota-parts-system-to-find-order-parts.113808/

Toyota's parts sites tend to be complete shit for hunting. The EPC site in that thread, your part will probably be under engine section, in one of the four or five Air Conditioning parts sections.

 

yeah, I was in there first, but its not entirely clear either. I will keep digging though...

 

SHE'S ALIVE! My son and I successfully finished the timing belt today. She fired right up once we reconnected the battery. I'm proud of what we learned and glad I'm not worried anymore and can do it again in the future. Thanks for everyone's help!

 

Jumping on this thread because it helped me fix my blinking A/C light issue. My ground cable wasn't even connected and the screw head was completely stripped. What worked eventually was similar to what @shifty` had suggested above, but instead of a Dremel tool I used an oscillating multitool to cut a slit into the screw head which allowed me to use a flathead screwdriver to undo the screw. Blowing nice and cold now, just in time for our first ever Alaskan heat advisory! Thanks y'all!
