X3 on the marking and get that front end up when you bleed it.

I think that's what it is. I had it filled to much. I checked it and it was overfilled based off the coolant mark. Drove it for about 50 miles today and ran like a dream.

The system is designed to operate under pressure when at operating temp and what you described as steam may have just been pressure being released, with a little coolant making it seem moist.




Actually there is a fill mark on the reservoir (see attachment). The words COLD LEVEL are molded on the top and there is an arrow on the side pointing to a level about a 1/4 inch below the seam.

kudos on the PDF. Where did u find it and if you say owners manual, I'm gonna kick my own self in the ***. I took some out while it was cold and no issues. I think I just had it too full. Not waterfall sounds and everything seemed to run like a champ. Gonna be fun when I start on everything else. Next is a new front driveshaft since the ding dong who built this one made it a pia to grease it. Gonna order one where I can grease all 5 points

Yep figured it was to full. I went by the house for lunch today and yep my 03 parts truck has the fill level markings on it.

I've never really seen the level in the reservior ever go up past where I have it filled to even on the hottest of days.

On the 02 D2 I quickly sold (wasn't the D2 for me) if the level was right on that mark I got the waterfall sound in the dash. Put the coolant 1/2 inch above the seam (technically overfilled = no waterfall sound in the dash). It ran 229F when I bought it due to a frozen shut thermostat. After I replaced it I was down in the 193-204F range and I did have that one **** coolant once when I went beyond 1/2 inch above the seam.

Air bubble wise I don't raise reservoirs, front of the LR or anything. I take my time let it reach 195F shut it off & let it cool down, then I fill the reservior back up, remove the vent in the T and top it off, then I run it up to 195F again and repeat the above. After that I top it off if needed, and I'm good to go after that.

i bled it according to the rave manual 4 times then did it when it was hot and the thermostat was open and barely cracked the bleeder plug and it had it coming out fine. I think I was just nervous as hell after all the down time and rebuilding for something so simple to get me

Bleeding isn't a consistent technique.

You can fill the bottle, raise it, and Crack the bleeder and still have air.

It's not a science.

I have found, parking on a hill, steeeeeep hill, with the front up does help, I say this because everytime I do it this way I'm successful

That's how I did it after the first 4 times and got it to operating temp. I went up a hill and stopped and tried it. Seems to work with no waterfall sound or anything. Think I was just nervous n had it over filled

Works even better if you park nose up on a steep hill over night and then open the bleeder first thing in the morning before you start the engine. top up as needed through the bleeder hole.

I also had luck with this method on the flat (cold engine) and that worked for me too... but I live on a steep hill and so i used it. Usually if the choice is parking nose up or nose down I prefer parking with the nose down so as to keep more oil in the oil pump.

14. Start and run engine until normal operating
temperature is reached, and check for leaks.
15. Switch off engine and allow to cool.
16. Check for leaks and top-up coolant to cold level
mark on expansion tank
If done by the manual you do it once then check when cold and simply top off when stone cold, preferably waiting until the next morning. When the paranoia creeps into the brain cells people often forget the procedures and do dumb things.

For those that do get a waterfall sound it may be caused by trying to rush the filling. It take time for the coolant to flow into all the hoses/passages and the air to escape. You don't need to raise the reservoir a mile high. Most important is slowly adding coolant to reservoir during filling after a drain. Filling too fast will block the escaping air. If you do get the WF sound shut it down, give it time to get cold and repeat the fill routine.

min01, thanks for finding the fill mark illustration, looked for a photo yesterday and found none.
