coolant change questions
Ok for give me on this but its time to change the old coolant again and money is tight now,like its not for all of us,so i wish to change it my self.
Tools and know how is not the issue but i have heard horror stories on hydro locking the coolant if not careful.
So whats tricks have you all come across in the proses of such a maintenance?
And for kicks and giggles should i go ahead and change the hoses and thermostat at the same time?

I had to do mine a month ago because when I was checking the fluid a small rubber hose fell into the radiator. I just pulled the bottom hose off of the radiator and let the water run into a 5 gallon bucket. Its probably not the best way to do it but I only had a short amount of time to get the small hose out of the radiator.

There is no need to change hoses and tstat. How many miles are on it? When I changed my water pump, I kind hydro locked the truck. Just fill the tank up and let the engine run for a little bit. Then, turn it off and add more fluid as needed. I had only about half filled and knew it. It started to screw with the timing will we test drove it. That was my stupidity.

Thats why im double checking
78 k now and had it originally changed at about 50k about 3 years ago but its looking nasty in the resivar tank so its time to change it again and you cant change fluids too much in my opinion lol

Not a bad video, that will do.
But for a thorough job get a flush kit. Easy to install and it flushes your entire system.
Don't worry about air bubbles. Never heard of hydro locking you engine while doing a coolant flush.....unless you shove the hose into the air intake while the engine is running....
Anyway. Follow the instructions that come with the kit and you'll be fine. When it's all said and done, leave the rad cap off and run the engine, the air will find its way out.

This is a cooling system flush procedure that I have found to work very well:
1) Drain cooling system by removing bottom radiator hose at radiator
2) Remove thermostat, replace thermostat housing with just gasket
3) Replace bottom radiator hose
4) Fill system with distilled water
5) Run engine 4-5 minutes, make sure heater is in "HOT" position
6) Drain cooling system by removing bottom radiator hose at radiator
7) Repeat steps 3 to 6 until coolant comes out clear
8) Replace lower radiator hose, remove thermostat housing, install new OEM thermostat, and new gasket
9) Fill system with 50/50 ** mixture of antifreeze/distilled water. Fill coolant reservoir with 50/50 mixture of antifreeze/distilled water
**Note: calculate amount of antifreeze based on total cooling system capacity to compensate for distilled water left in block.
10) Run engine until operating temp is reached (thermostat opens), shut engine down.
11) Allow engine to cool, then top off cooling system with 50/50 antifreeze/distilled water mixture
