Lifeguard's engine compartment is a much cleaner, nicer version of mine. The places that he has circled in the photo is where mine are also. Trust me GM would not have spent the money for 2 senders without there being a reason. I have heard that members that put a gauge in the head the gauge reads too high compared to the water neck. I am going to put my gauge in place of the sender in the water neck and leave the one in the head hooked up. Still wonder why it was done though. Jay
