Do you have to remove the large PCV hose coming out of the block?

Replacing the ECU Coolant Temp Sensor in my swapped 1996 EJ22-ish Legacy.

They all crack when removed so I'd rather leave it in place.

Off to see if I can find out what size that hose is so i can just replace it if needed.

 

How to guide on replacing the sensor:

You mean the big one that comes out from the top of the separator place? With the plastic fitting that always cracks and ruins your day?

Yea, IIRC you don't have to remove that, it helps, but it isn't needed. You should only have to pull off the one that goes to the IACV.

It makes the job much easier just to remove the IACV, so if it needs to be cleaned, now is a great chance to do it.

Use a hair dryer or a heat gun as it will make the PCV lines easier to flex and not crack

Gary:  I have replaed several of those sensors and I have Never taken the PCV hose off the block.  I haven't removed the IACV either.  It makes the jpb a bit mor tedious, but not removing those extra parts made the job go a little faster.  I also lost less coolant.

 

Good luck.

thanks guys. where i live it's not convenient to start a job and need
something, and i don't know if it's where i live or what but pretty much
every 1990's or earlier large PCV hose in the block has cracked for me
when removing it.
