Hi, had a coolant leak a while back and ended up topping off with water during a journey, anyway want o drain off the coolant and replenish with pure antifreeze before the big freeze heads our way. Where is the coolant drain 'plug'? Had a look all along the bottom of the rad but could not see anything that looked like it? tip or picture would be appreciated

 

Best way is to pull the lower radiator hose. I hate using the Radiator drain. Sometimes they get seized in overtime, you try to force it out, it breaks.

 

2nd the lower rad hose, also if you live in an area where road salt is used I would inspect the metal pipe that the lower hose connects to going to the engine as well. Its common for them to rust out.

 

Radiator drain is on the drivers side bottom of the radiator. I very rarely have issues with it. Connect a piece of hose to the drain nipple and into a bucket and little mess to clean up.
