Mayellah Posted July 5, 2020 Report Share Posted July 5, 2020 (edited) Hey, Back again with more problems and $0 to throw at a mechanic. I was told that I should have a coolant flush done, and it's also recommended in my maintenance book. However, I'm hearing conflicting answers. I'm having a whole bunch of problem, which I'm not sure if it's related to not having this done. I have 122,000km and this procedure has never been done before. I have to top off the coolant about once a year ( 8oz or so ), but see a "grit" or sediment at the bottom of the reservoir. Should this flush be done? Is it difficult? From the youtube vids, it seems fairly straightforward. My reservoir isn't pressurized, and I have the cap for my rad. Would A/C issues have anything to do with this being neglected? Thanks Edited July 5, 2020 by Mayellah Quote Link to comment Share on other sites More sharing options...
OhareFred Posted July 5, 2020 Report Share Posted July 5, 2020 Yes, do the flush. It cleans out the entire cooling system. After awhile your coolant loses its protective qualities and needs to be done. If you can afford it, have it done with a flush machine. If all you do is flush the radiator, your only doing part of the job, but if that’s all you can afford, it’s better than nothing. the only way this might affect your AC is your cooling system may be running warmer than it should, making everything hotter. The AC system really is not directly connected to your cooling system. Mayellah 1 Quote Link to comment Share on other sites More sharing options...
Mayellah Posted July 5, 2020 Author Report Share Posted July 5, 2020 What do you mean by "flush machine"? From the vids I watched, they say to use a Prestone cleaner & flush for 3 days ( 6 hours of driving ) before performing the flush. Drain coolant, replace with distilled water, run engine and heat for 20 mins, drain, and repeat distilled water until it runs clear. Fill with new coolant...

OhareFred Posted July 5, 2020 Report Share Posted July 5, 2020 You can go to a dealer or most oil change places, they hook it up to a machine, and in about 30 mins or so your entire cooling system gets cleaned/flushed and new coolant installed. Mine cost about $200 at the dealer. 2late4u 1 Quote Link to comment Share on other sites More sharing options...
NavalLacrosse Posted July 8, 2020 Report Share Posted July 8, 2020 Or, the bad advice: Do it with a garden hose (don't do this!) Quote Link to comment Share on other sites More sharing options...
Summer Solstice Posted July 8, 2020 Report Share Posted July 8, 2020 You can do it yourself but after labor and materials is it really worth it. The possibility of an air bubble on this vehicle is high and that is a pain to work out. Quote Link to comment Share on other sites More sharing options...
2late4u Posted July 9, 2020 Report Share Posted July 9, 2020 (edited) also if you are having to add coolant once a year. you have a very small leak somewhere,,,,first replace your rad cap since its a 2011....you should never have to add coolant...good luck i had mine done at the dealership when i was having my plugs changed ( 3.6) wasn't a bad price compared to the quick change places Edited July 9, 2020 by 2late4u Quote Link to comment Share on other sites More sharing options...
