how do you do it guys. do u unscrew the drain bolt for it then fill it up from the thing under the hood till it gets between the low and full mark?

The thing under the front hood is just your overflow resevoir. It needs to be drained and refilled also, but filling it only will not fill your radiator. You have to undo the bottom hose like jumbo did and then fill the radiator up with either a 50/50 mix of antifreeze/coolant and distilled water, or you can get the premixed stuff now also! The reason I say distilled water is because the impurities in regular tap water or drinking water will cause you radiator to get corrosion in it. Hope this helps!

use the drain bolt on the bottom of your water pump... it's way easier than pulling off a hose and it is the lowest point at which the water flows. give the kick start a couple kicks to get out ALL of your old coolant. fill your new coolant to the top of the radiator then put the cap on and fill you over flow.

I pulled the drain plug on the water pump, sat there with nothing coming out and then :11doh:

Loosen the rad cap...I didn't expect the coolant to fly half way across the garage though!!! :angry: Stuff comes out like a frozen rope!

fo rizzle...it prob. made a bigger mess with me when i took the drain bolt off and then took the cap off then when I just took the hose off....good thing its animal friendly cause it covered my whole basement floor

The only thing that made a bigger mess was when I changed the tranny and transfer case oil in my Taco. I broke the drain plugs loose and started draining the tranny, little did I know that the transfer case was dripping in my hair!!!

Friggin gear oil STINKS to high hell!!!

By the time I was done I had it splattered over about 7sq ft of the garage floor!


:mad:

I was told by a friend that the wetter water is bad because it dries out the water pump seals. He has had firsthand experience on his CRF Motard. I just dumped it in my bike last week, so I'll be draining that out and putting in Engine Ice.
