Radiator fluid flush

I wanted to flush the radiator/fluid in my '97 VFR last weekend but quickly realized that there is no drain plug (that I could find). The Owner's Manual says to 'have a qualified mechanic' do the job. Other than pulling off hoses, is there an easy way to drain the radiator fluid?

 

I would check for a small bolt on the bottom side of the water pump housing. All of the water cooled street bikes I have owned had a drain plug in this location.

 

Here is a link to VFRD where you can download various service manuals. They have the 98-01 manual and the 90-96 VF750 manual. Not sure where the 97 falls into the mix.

There should be a drain bolt on the water pump.

Here is also a great how to on flushing the coolant on a 5th Gen...it may help you.

AS stated......


bottom of waterpump, 10mm head, small copper washer underneath.

It's good to let a garden hose run for a few minutes through the filler cap opening.

 

no................................................................. you need to flush it with distilled water not to corrode the inside of engine..then run at least 50-50 mix with distilled water the expensive stuff (radiator fluid)is better and can last up 100k miles also may want to consider running a flush kit additive half only let bike run a few minutes and then drain...good luck...I'm not even gonna comment....

 

OH, god, again???


Corrosion takes time, and a 10 minute flush with tap water won't hurt anything !
