Need help with thermostat install.
First of all, open the coolant cap to let out pressure, then put it back on before starting. This allows a minor vacuum to develop which helps a little to reduce coolant loss.
Next, don't take the hose off the thermostat yet, just pull the clamp back.
Now, swap the stats. Since very little will come out of the hose since the stat is still connected, you can just deal with the motor side. If you hold the stat in place while you take the bolts out, you will lose very little fluid. Do a quick swap and you lose maybe a cup or so. Put the bolts in. Now just pop the hose off the stock stat and quick put it on the new one. Install clamp and you are done.
I've done this easily a dozen times this way, you should be able to do it without losing much more than 1/2 quart or so.
Just my .02 with what works for me.....
