OK, I got the 350 from the motor shop today, been working on transferring over all the stuff from my 305. I have 2 questions.

One, There is a sensor that is right above the oil filter. What is this thing called? And what is the best way to get it out? it doesnt appear to have a nut on it, it looks like maybe it requires a special tool ??

Two, The sensor on the passenger side Head that appears to measure coolant temp. What is this called? It is missing the little tab for the wire to plug into, so I need to replace it.

Any help is much appreciated here guys.

 

#1 oil pressure switch, it should have a metal base on it that you can grab with some pliers.

#2 coolant fan switch, this turns on the fan when it gets to temp.

 

Thanks,

I got it out, wasnt sure if I should just use a set of pliers or not.

Took a few trips to different auto stores to find the pass. side temp sensor too.
