To flush or Not to Flush before coolant filter

The question is do u flush before or after. I was thinking before so when you install the filter the coolant will be clean plan on doing this tommarrow since its suppose to be nice

Your assertion is correct. Flush first, then add coolant filter.

Yes, flush before you add coolant filter. Besides the above mentioned, a coolant filter bypass is just that, "a bypass set up". Which means its designed to bypass the coolant flow so if the filter every becomes totally clogged, it won't restrict coolant flow to the motor. Also, coolant filter bypass systems only filter about 10% of the total coolant of the system.

well i did it differently, i installed the filter first. and when my first filter is up, ill flush it and swap to elc. my reason was i didnt want to filter out what was left over from the flush and get most of it out the first time. plus the filter is only 10$ so it doesnt matter to me. and the person ill take it to get it flush is a drive from me.

Do the flush first. After your final drain, just before you are going to fill with the new coolant, go ahead an install the filter kit. That way things will be empty while your hooking things up. If you have concerns about the age and/or condition of t-stat, this would be a good time to replace since you'll have things drained.

Go ahead and change the thermostat out while you are at it.

Kinda of a waste of a perfectly good working thermostat. She has another post going on, her EOT is 190-192.

Get the crap out ASAP and then put on your new filter. The thermostat is easy enough to change anytime so I decided when I did mine not to change it til it failed which it hasn't yet and that was about 10K back. Do remove it to make the flushing process quicker and replace the o-ring when you re-instal the thermostat. Note: even after the flush you'll be amazed at how fast the first filter will plug up. Mine first lasted just 500 miles.
