Does anyone happen to know offhand what size these are to remove on a 90' F150 302? I just don't have the funds to go buy a set or anything. Thanks.

 

Pair of pliers works fine for me.

There's a special socket, but there's a special tool for just about everything.

 

Mine have never been removed and with 257,000 km/s on the stuff in the block it ain't easy. I tried the pliers believe me.

Sorry nevermind. The special tools on 15$ so I'll just go grab that.

 

If you don't mind destroying the sending units, then vise grips will work.

 

Ha, I don't mind at all. What are they really good for anyways? I just can't get in there with vise grips. I already unbolted the right bracket to get easier access. There just isn't enough room.

 

wich one are you changing? the water temp sensor? i have the new one with the new aftermarket water temp gauge.. is it hard to change?

 

Not really, no. Mines just extremely corroded. The water temp sensor needs a 1" deep socket.

 

NAPA,Advance,AutoZone should all have the special socket. Fits the oil sending unit perfect.

 

Well if anyones interested in this for future reference, the new electrical sending unit won't fit without the block interfering. I guess you guys are going to get your way after all. Mechanical it is.

 

I take it someone here has used the mechanical oil psi gauge from autometer with success? I hope? I'm about to order it and the last thing I need it another 50$ paperweight.

 

the electrical water temp gauge doesnt work? with our trucks? or wich one are you talking about.. becuase i just buoght a new electrical water temp guage.. and im getting it installed 2day

 

It's not a standard size and a regular socket (even a deep well) won't fit. It's really does require the special socket. Also the tool holds the sender tight so it doesn't fall out when removing it.

 

ohh sorry i misread.. you where talking about the oil pressure guage.. ok no prob.
i will post some pic of the installation of the water temp guage later today

 

please do...I've got a 3 pillar guage in my truck that I'm going to be hooking up pretty soon.....

 

Just get a short length of pipe or go to a junkyard and look for an 87 or 88 V8 truck and grab the extension. It's just a 1/4 NPT thread, so you should be able to find something to move the sender off of the block. No sense spending more money for something you already have.
