I have a 97 Celica, and finding the correct size nut was a VERY frustrating ordeal. I finally had to go to a Toyota dealership to purchase them (Home Depot, Lowe's, Ace Hardware, even tried KMart, all didn't have the correct size). Didn't matter if I purchased metric nuts or not, Toyota seemed to had made the nuts for there O2 sensors special.
Anyways, the dealership ended up special ordering the for me ($2 a pop). I think they referred to them as self-locking nuts. Anyways, even I installed them, it was a very tight fit...but eventually got them on.
Hope any of this helps. The thread size is metric M8x1. It is not available in most stores. You can buy a machine tap and make your own. An equivalent American size is 5/16-20 UN. It's a very rare size, so don't even bother looking. If you decide to make your own nuts, I suggest you use 300 series stainless steel.
It's right hand thread. I just change the timing belt on mine today. I think you should spray on some DW40, It'll help to loose it.
what size thread is the oil switch sensor in a range rover 1994 4.2 v8
The part the flange screws on to may be a piece of all thread that can be changed for a longer one. If the stem of the faucet is not long enough now, you may have to get flatter flanges. If it is the stem not coming through the flange, I believe you can get extensions for the stem and a longer bolt to hold the handle on.
M14x1.5
12 x 1.5
You will need 8 bolts with 5/8" diameter, and 3 1/2" in lenght.
The manifold absolute pressure sensor is installed in the intake manifold it is a simple installation thread in thread out.. but it is in various locations on the manifold depending on which engine you have The chilton or haynes manual will show you.
m18x1.5 is the threading for Honda civic/del sols, and probably most other o2 sensor bungs
See the thread here on cleaning the MAF sensor for details of its locationhttp://www.celicahobby.com/ubbthreads/showflat.php?Number=1862388016
18 Millimeter, 1.5 Pitch
Use the manual or the colour coded threading guide that is inside the front part of the overlocker. Simply pull down the compartment flap where the 'Toyota' logo is and you should see the small diagram. Followed carefully, it's quite easy to re-thread each looper & needle(s). Hope this helps!
Using an angle drill, drill a small hole in the sensor. Thread a screw in the hole, and use it to pull the sensor out.
