for those who knows the H22 well, please tell me the locations of the following items. detailed description would be wonderful

1. Water temperature sending unit.
2. Oil pressure sending unit.

If once i find these locations, and put in the aftermarket gauges to measure the parameters, do i have to remove the stock units? Would this inturn affect the ECU and throw any light?

Thanks in advance guys.

ps. please no vague replies

Well, I know for a 4th gen h22(which should be the same location), the oil pressure sending unit is right below the oil filter. It is a small electrical connection that you have to disconnect, then remove the collar-bolt that it attatches to and install the center piece for the sensor. I just did this for my turbo oil feed line, it was the easiest part, good luck!

I have the entire Helm's manual on my computer in PDF form. If you want the Engine, Cooling section I can email it to you, but you have to have at least 39 megs free. PM me if interested.

i am warning you do not use brass fittings in the engine block only use steel, and for the oil pressure i used a fitting on the side of the head where alittle plug is much easier to do it this way. yet again do not use a brass fitting in the head or engine block.

wow thanks for the warning, but please explain to me why brass would be a no no...because all the fittings i have are brass.

What about the water temp unit? where is it? Any light turn on/disabled once i remove the stock sensor ?
