my thermastat is messed up so i am gonna change it, and in the process i wanna flush out my coolant and add new fresh coolant... 92accord ex is what i got, i know about the drain plug and all that.. curious if i have to really do 50/50 water/coolant or just more coolant and a little bit of water.. thanx in advance

dont forget the drain bolt on the engine block to drain the coolant out of there. Run water through the entire system after you drain it all to clean it up a bit, drain the water out before refilling w/ coolant/water mix. I personally use 50/50, but its all about how much you want to put. Some people use more water, while others use more coolant.

OEMaccord

dont forget to use distilled water

patastinky

distilled? i cant use tap water out the hose?

OEMaccord

you can, but its better to use distilled.

iam7head

do it when the engine is not hot or too cool
warm=more complete flush, cold water can crack that bi_ch up if it's
too hot.
50/50 works well.
becareful about the coolant, where to loose them and all that.
dont let your dog, family drink it..
and yeah..it eats away paint if you dont wipe it out..

patastinky

thank you everyone for the help..

Just use distilled water, cuz the tap water has minerals still in it and that can lower your cooling system efficiency, and do what iam7head said, after drained, put some distilled water in, and start the car and let that cicle a lil on the engine, so it will clean the rests, drain that and put your mix, you can mix it in a bucket and then pour it in the radiator, remember, fill the radiator and turn the car on, without the radiator cap, and keep toping it, after the radiator and engine are full, fill the reservoir (halfway) and you're done

patastinky when you do the flush dont wash the coolant down the stormdrain. thanks I see alot of getto people do that sh*t . I'm not your local tree hugger just your local surfer.

patastinky, i went through the same process a coupel weeks ago. its not that hard at all. for coolant, i probably used 60 coolant and 40 percent water. it really doesn't have to too precise. its a good idea to add coolant while the car is running and the cap is off so all the air throughout the coolant system can be expelled.

good luck, and make sure you put the thermostat in correctly and make sure the gasket is ok.

Most of the coolant that you will find in an auto-parts store is already mixed, just pour it in I went through the same process when I destroyed my radiator, piece of crap Honda plastic, anyways good luck

then why do shops have to dispose of used coolant?

dude you dont want to put anything down the storm drain , in california you get a huge fine/and or prison if you get seen putting anything but water in a storm drain. even soap.( there is a bio- friendly soap you can use on cars )...........

Keep in mind the sheer quantities shops get and remember it IS toxic. Its always best to have a shop dispose of any large amounts of chemicals, but if you dont, like it was said above, make sure its part of a municipal system, coolant does bad things to little critters in drain ponds.

wear gloves when you do it also. i was replacing my upper radiator water hose w/o gloves and i guess the coolant has some chemicals in it that my body reacted to and i started gettin red spots on my arms and sh*t. ran and took a shower and thankfully it went away shortly.
