HamrTym Posted August 9, 2008 Share Posted August 9, 2008 In the next couple of days, I will be draining and replacing my coolant in prep for a track day, my first. Didn't someone once post a how to as far as the best way to completely drain the cooling system. Unfortunately, my Honda service manual is buried in the depth of a 10 x 20 storage unit. Obviously yanking the lower radiator hose and draining is a start. Any tips or advice would be great. Thanks. Rob Quote Link to comment Share on other sites More sharing options...
jcrich Posted August 9, 2008 Share Posted August 9, 2008 That is all I do on the Suzuki's. Pull hose off the water pump and drain. If you have anti-freeze , you will need to refill with distilled water a couple of times and drain. Fill it up with the water, run it a little, shut off and pull the hose again. Use distilled water and Water Wetter for your fill for the track. Read the Water Wetter directions, you only need a cap full or 2 for the amount of water in the cooling system.

HamrTym Posted August 9, 2008 Author Share Posted August 9, 2008 Thanks Rich. Out of curiosity, will the over flow catch tank drain also with the rest of the cooling system? Or just disconnect the small hose and use it to drain the coolant catch can? Thank you. Quote Link to comment Share on other sites More sharing options...

I recommend a vacuum pump, as coolant tastes like crap BTW, there's also a 10mm bolt on the left front of the block that you're supposed to remove to drain the block. Not crucial, but if you want to get it all.... Quote Link to comment Share on other sites More sharing options...
Keith Posted August 10, 2008 Share Posted August 10, 2008 On the 'bird you don't need to pull any hoses. There's a bolt on the water pump that will allow you to drain most of the coolant. Remove the plug on the front of the engine, as Redbird points out, to get the rest of it out of the block. Then proceed as jcrich outlines.
