I just flushed and filled my coolant. But i also am still getting this waterfall sound. What can i do to fix this?

 

Bleed the system. With it stone cold (overnight), unclip the reservoir and set it on the battery box cover making it the highest point in the system, and remove the bleed screw from the upper hose/tee. Fill the reservoir until you get a steady stream out of the bleed screw opening, then reinstall the bleeder screw. Finally move the reservoir back to its proper location.

 

230 is like nuclear meltdown... or am I missing something

 

I thought i did that part already. Is it normal to need to bleed more than once to get all the air out? I guess i will try again in the morning.

 

Good work.
There are three hoses and you have them all back on.
You should now bleed the system.

That white tank is on a clip.
Lift the front of it off the clips.
The back is fitted into the body.

The hoses are long to allow raising the tank 4 to 6 inches.
Fill it up with antifreeze.

Run the engine at a fast idle for about 5 to 10 minutes.

If the coolant lowers, then put more in.

I usually do this with the cap off.
Coolant should not come flying out.

Once about 10 minutes is over, fill it up to the hot line.
Put the cap back on.
Fit the tank back down where it was
clip it in.
Test it for proper level and it should be bleed.

Check it every few days thereafter until you trust it.

Others will say use the bleeding "T".
I ignore that "T" and I bleed as above.

 

That's what I thought too...

 

Have you been doing this with the front end of the truck elevated? (i.e.- parked facing up hill, on ramps, etc...)

If the truck is sitting on a level spot, it can be tough to get the air out of the heater core. The further you can get the coolant reservoir above the rest of the cooling system, the easier it will be to bleed. Doing this on an incline with the front of the vehicle as the highest possible point helps a lot...

 

Yeah, especially if that was the temp when he shut the engine off. It probably went up another 5+ degrees when shut down...

 

Personally my goal has been to keep the temp under 200. my 2000 runs 197 in stop and go. When i put a 180 on my 99 i was still getting 207. So i aM changing the radiator. It still had dex. I just want to be safe..
