Ok, im at my limit with this 5.9 magnum engine in my vehicle. 3-4 months ago, i had a coolant leak from my timing cover gasket, replaced that gasket, and reused the old water pump. 3 weeks later the old pump started to leak bad. So i replaced that 2 weeks ago with a GMB "new" pump. I was checking it for a few days on and off and i noticed no leaks except the weep hole was leaking a tiny bit, but barely enough to even make a smear on my finger.. I knew that might be a problem but GMB said its normal while the seal sets.

So being frustrated and tired of spending money and workong on this Piece of junk i decided to just drive it and wait and see, since the thing has a lifetime warranty. Well its been 2 weeks now since install and i distinctly remember when i filled the coolant up the reservoir it was Just a tad on or under the full line. Now its a good 1 inch under the full line (between full and low) when HOT... I need to check it tonight when it cools down... i havent checked the level in a week nore the underside for leaks...

However when i check everything after i see the level like that... its all dry, no leaks, no lines or marks for dried up leaks, even the waterpump when i felt the lip on the weep hole felt dry. Could it maybe be the level dropped because some air was still in the system when i replaced the water pump (drained the block and radiator) but even then would it really take 2 weeks ( i dont drive much tho maybe drove 250 miles in those 2 weeks) to finally burp all out ?

I dunno what i should do, because im at my wits end here.. im tired litterally tired of working on my car.. I dont think i have a headgasket issues either as im pretty sure i dont see white smoke out the tailpipe and the spark plugs look ok.., nore does my oil look creamy, on the oil fill port or the dipstick or when i changed the oil 100 miles ago...

What should I do ? Keep driving it for another 2 weeks and see if the level drops another inch or what.. ? Cause like my heart is litteraly hurting from this stress this vehicle is putting on me... im getting tired of it.. and im going through finacial problems so i cant just fix it every week... I dont even know what to fix now because i dont see any leaks anywhere on it

 

Very well could have been some more air in the system. Fill it back to the line.

 

But would it take 2 weeks to finally burp it all out ? I only drive in the city, maybe 8-16 miles per day.. So i dont drive it much like i said maybe drove 200-250 max in those 2-3 weeks.

 

We're talking about an inch here. jeez

 

If you don't perform the "burping procedure," it may take that long.

 

I've never encountered engines more difficult to burp than these..

 

What is the level in the coolant overflow? Has it been constant. You may want to look at radiator cap as well. It could be that it took that long to get the air out - it isn't much lower. A leak would be more significant I think.

 

I believe thats the level the OP is talking about(overflow bottle)

 

This.

I would be more concerned if in a days time the bottle was empty.

 

Heater core maybe? Mines using coolant and I realized the other day the heater smells like coolant...
