Thanks I did the thermostat last year and I went out and bought a cheap short socket set at autozone. Took off the intake the lines and I was able to change it with a swivel 1/4 attachment.About an hour total. It was very tight in there tho. The worst part was I dropped a bolt down by the thermostat housing had to go back to the auto parts store to get an extension magnet $6.99 save my but tho. My hands would not fit in there lol
