I got that picture from the fsm and I thought the little sender was the one I needed to take out. It almost looks bold in the picture so I was sure that was it. Well it wasnt and when it came out so did a whole lot of coolant.

So which one is it?

 

The big one.

 

It's the larger one with the 12mm (?) collar fitting. I just replaced mine a few weeks ago. You're gonna love to see the 100 psi (at AWS) in the Mornings and the 60+ psi mark at highway cruise.

 

What is the best way to get to it?

I took the throttle body elbow off and was still having trouble getting to it.

 

O BTW will oil come spewing out when I remove it?

 

I was able to replace mine by getting to it from underneath the car. Oil will not spill out when you remove it.

 

It will spit oil if the car is running ...just be careful so you dont overtight the new sender..and btw,how much did you paid for it?
