Anything that is vitally important when i install this. Any help or suggestions are appriciated! Thanks!

Just take the two bolts off the t-stat housing, pull it out, swap the t-stats and bolt it back on. Then take the radiator cap off and top off the coolant.

Start the engine, with the radiator cap STILL OFF. While you're waiting the approximate 15 minutes for it to get hot enough for the t-stat to open...massage the upper and lower radiator hoses to move the coolant through, that should take care of all the air bubbles. Works every time. You'll see little bubbles coming up in the radiator fill neck.

I did a coolant flush yesterday and when I do I remove my t-stat and just pull the drain plug and let it run like that for 15 minutes. It flushes every drop out that way. Then I put the t-stat back in and do what I said above.

Just make sure you're bouncing back and forth watching you temp guage just to make sure its not getting too hot...IF a bubble does cause a problem.

The lower hose will always have coolant in it. But if you feel the top hose has nothing in it, squeeze the lower hose alot more.
