Why you should upgrade to an aftermarket performance radiator
A radiator is a vital component of any liquid cooled engine. With a cracked or leaking radiator, you constantly run the risk of overheating your ride. At the same time, even if your radiator is fine, if it's not bled properly it will have air pockets that can result in fluctuating engine temps and possible overheating. If you plan on racing or doing any sort of extended spirited driving, an upgraded aluminum radiator is one of the first things that should be taken into consideration.
This is a brief description of how to remove, install, and bleed an aluminum radiator on a liquid cooled engine. There are a variety of techniques that can be done to have the same end result, this is what we’ve found most efficient and effective.

Step 1: How to drain a radiator
**MAKE SURE ENGINE IS COOLED DOWN FOR THIS PROCESS
****A quick and dirty way to drain your radiator would be to just remove the lower radiator hose completely, and the coolant will come rushing out. This will make a mess of your workspace. We do not recommend this.
Step 2: Remove the Radiator
At this time it is recommended to replace your thermostat. Especially if your car was overheating before beginning this install there is a likely chance that your existing thermostat could have been damaged.
Step 3: Prep/Install New Radiator
