after this install, do you have to perform a full coolant drain and refill? or just some type of purge/de-airing cycle if needed?Confirming it is a direct bolt-on. Two bolts to remove the coolant tank and 3 bolts to remove a bracket so you can get the larger hose disconnected.
I followed this video for installation.
Note: Keep in mind that there is no need to replace the mount with the Mishimoto expansion tank.
also, being fully aluminum, how do you see/check the coolant level. i can't seem to find any markings/gauges in any of the photos
