im looking to flush my coolant in a little bit, my question is about cleaning it out, i know how to drain it. do i just take my hose and run water through it? or do i have to turn the engine on and turn the heat on?

 

I used the flush kit that splices into your Heater hose, so you can hook up the water hose to it.

I unhook the top radiator hose (return) after draining coolant out rhu the petcock on the bottom of the radiator, hooked up the garden hose to the flush connector I installed on my truck, and flushed till the water was clear coming out of the radiator. Closed everything back up and ran for a few minutes with a full cooling system of water, then drained and flushed again.

Then, I put the coolant system "super cleaner" in my truck and ran for the 3-6 hours that was instructed on the bottle. After that was done, I flushed it out a few times the same way as above. I flushed it twice with DI water (De-Ionized water, distilled water) I get fromt the plant here the same way as above minus the garden hose hooked up. Afterwards, I drained all the DI water and put in the antifreeze, and DI water to the specified % listed in your repair manual/service manual. You could always buy the premixed stuff as well to avoid buying distilled water. Whatever you do, don't leave tap water in there as a permanent additive to the antifreeze, use only distilled water to finish it off.

Kind of legnthy, but I hope this helps, and good luck.

 

thanks man, now what this flush kit thing? ive seen a hook up online for a garden hose that goes right where the radiator cap goes is that what youre tlaking about? do you think after i flush it out with plain hose water i should run some distilled water through it? or will it be ok to just let all the hose water run out and then put the coolant in? i know not to add hose water bcz of the minerals in it.

 

Magnesium and Calcium make up the hardness in water, which builds up in the radiator. Run distilled water thru it, and on final fill, put distilled water + antifreeze back in it, or fill it up with the 50/50 premix stuff, whichever you prefer. That regular water enhances electrolysis in aluminum for sure.

The garden hose connector goes in line with your heater hose, and has a cap in it when you remove your garden hose, you just cap it off. You can purchase this kit for ~ 5 bucks at autozone, that's where I got mine. I have even seen them at Wal-mart.

 

thanks alot! yea i found the connector at oreillys for $3.99
