I want to do a radiator flush and change the thermostat, i have a 04 hemi 1500 . was wondering if there is a drain plug or hose on the bottom of the radiator ? or where the lowest and best point is to drain the fluid is ? anything else i should know or so while i am doing this process would be great to know also !!! thanks

 

id like to know to but i have a 4.7

 

i've always just pop the bottem hose off and take a garden hose and spray into the top of it lol... its pretty redneck but it works. make sure you have a couple 5 gallon buckets around

 

There is a drain plug on the drivers side bottom of the rad.

 

Weeds' right---duh!

Actually, the fsm says to just open the drain to a bucket without opening the rad cap, this will pull all the coolant out of the bottle too.

There are also plugs in the bottom of the block (NPT fittings) I think they're 1/4" that can be removed for a complete drain. I installed drain ***** when I did mine last.

 

cool thanks guys

 

so open drain plug and just let it drain without truck on right... thanks guys

 

Yes and try to refill using distilled water

 

might want to do an anti-freeze water mix if it drops below freezing in Illinois

 

yep did that , i did a 50-50 mix. i thought i was going to use more fluid but i only used 3 gallons . i guess thats not a full flush , is that bad that i didnt get it all out ? thermostat went in easy so that was good , i guess when i said radiator flush in my head i was thinking system flush. and come tho think about it i only did a radiator flush . im not sure how to get it all out ? unless i cant? thanks again for the replies guys all helped and were great info !!!
