A nice compact extinguisher for "Autos".....good for 12 years or one time use.......6 year warranty....all for $17.88

DOT approved.....

great size IMO.....will fit nice in the ZR-1

FYI.....check the bottom of your extinguisher before purchasing as I was told.....the date of manufacture is right there....here you see 2018....brand new and current.....can't do better than that.....

Dry chemical fire extinguishers are cheap, but if you use them they will make a god awful mess of your car and garage. Dry chemical goes everywhere & is really, really hard to clean up. The chemicals waft through doorways & spread everywhere. Plus it will permanently damage electronics....
I went another route and purchased a large 10# CO2 fire extinguisher for the garage & a 5# CO2 for the kitchen. CO2 dissipates into the air and leaves no residue of any kind (no chemical clean up). It also does not hurt electronics. The only damage you will have is from the fire.
The CO2 extinguishers are more expensive, but they will save you thousands in clean up if you ever have to use them.
Many years ago I used a dry chemical fire extinguisher to extinguish an engine fire, it was a very expensive mistake....

If anyone is interested, this is by far the cheapest place I found to get the CO2 fire extinguishers:

Shipping is not real cheap because they are a pressurized gas & there are limited ways to ship them. I also purchased a really nice "boat" mount that is child resistant for only $30 more.

Ever since I've owned the 94.....my AC has never been really cold and sometimes it just felt like regular outside air coming through the vents......just never got around to checking things out.....until now....
My compressor doesn't engage at all.....(I have not jumped the switch).....although the AC clutch turns freely inside the pulley..
And I don't have the "low freon" code.....so I did some research and decided to change out the AC clutch bearing..... I have also noticed for about the last 6 times or so that I used the Z.....that upon startup I was hearing a bearing noise that would last for a few minutes and then disappear..... I thought maybe it was the water pump....but no leaks there....and it wasn't the alternator.....so I'm thinking could it be the AC clutch bearing....
I figure try that first without removing the plenum....and if that doesn't work....well then...... I would assume some other parts may be defective.....or the compressor would be shot......
So here are some pics of the removal of the parts necessary to get to the clutch bearing......
In pic #1 & 2....
I had to figure out the best way to lock the compressor in order to remove the 10mm bolt in the center of the pulley....as you can see a large vise grips was used to keep anything from moving......and a 1/4 ratchet and 10mm socket to undo the bolt....as you know.....there is very little room to maneuver anything in that space.....
Pic #3 shows the AC clutch removed....and you may also be able to see a snap ring in place to keep the pulley secured......
In pic #4......it is highly unlikely that the pulley will just slide off with hand pressure....so again with limited space I used the 2 hammer method.....rotating the pulley after a few hammer taps....it finally slid off.....20180705_152051.jpg20180705_152107.jpg20180705_152801.jpg20180705_155317.jpg

Pics #1 & 2 show the parts on the bench and both sides of the bearing....
Pic #3 shows a close up.....which appears to be the original bearing.....
Pic #4 & 5 show the new replacement bearing that will be installed....
And pic #6 shows the coil which looks to be in fine shape.....not melted or destroyed like from what I read......could happen and it is a real possibility.....so I lucked out....

I don't have any AC knowledge.....so I'm learning as I go....
Next is to punch out the old bearing and install the new one....and hopefully that will correct the issue.....we shall see.....[emoji16][emoji16]20180705_160345.jpeg20180705_160349.jpeg20180705_160428.jpg20180705_160504.jpg20180705_160514.jpg20180705_160911.jpg

Finally got bearing out today after a soak overnight with WD40.....new bearing went in just fine.....used some Loctite to make sure it stays in place...
Another option for bearing install would have been to put the bearing in the freezer for a few hours to contract.....and then slightly heat up the inside of the pulley evenly with a small torch to expand.... and the bearing will (should) drop right in....
Also old bearing was shot.....just plain worn out...... finish the install tomorrow......the compressor should now work......20180707_222908.jpeg20180707_222918.jpeg

I know u are trying to avoid removing the plenum, but have u checked the ac clutch harness connector? They are notorious for cracking and disintegrating.

If you go back through the heart of the beast articles I did an extensive rebuild on the AC system for our cars and how to rebuild the AC compressor
