Dont forget to burp when you're done installing the rad (and after enjoying a cold beverage).
From Wiki:
1.During the initial fill, fill the coolant reservoir bottle to the top of the cold fill range.
2.Set the temperature blend selector to the full warm position and the fan motor control to high for the front and rear heaters. (IMHO...you don't really need to turn the blower on, just turning it to hot will get coolant into the core, the fan will just let you know when you're feeling heat)
3.Start the vehicle with the reservoir cap off and allow to idle until the thermostat opens
NOTE: the coolant level will drop quite a bit when the thermostat opens - that's most of the air bubble in the system being driven to the top of radiator and escaping. Without the air, there's more room for coolant.
4.Top off the coolant in the reservoir bottle to the top of the cold fill
range.
5.Install and tighten the reservoir cap.
6.Increase the engine rpms to 3,000 for 15 seconds, and then return to idle for one minute.
7.Repeat the previous step four times or until heat is coming from the rear unit while the vehicle is idling.
8.Allow the vehicle to cool and top off the coolant in the reservoir to the cold fill range.
