I've spent some time searching the forum for more information on this... but... my symptoms aren't quite the same as other things I'm reading.
Here goes:
Your basic 2006, 2500... higher top converted cargo-camper van.
1) In the morning after Sprinter has cooled down, if I check the coolant, the top BLOWS off with a lot of pressure (I use a towel so it doesn't bop me in the face).
2) There is NO OIL in the radiator fluid.
3) There is no water/white stuff/emulsion in the oil (I change it myself... 3 x's now...nothing, ever)
4) No white smoke out the exhaust.
5) I have been losing coolant... depends on heat and how much I drive. it's not a Ton... maybe 2 cups every 1200-1500 miles?
6) I had the radiator pressure tested... no leaks.... but there was a small tear in the cap, so we replaced that... it's been a few months... no change in anything.... still pressure blows on even a cool engine EVERY TIME I check (First I thought it was because I was going up and down in elevation!)
Also, I still have a consistent amount of coolant loss.
The coolant light is usually on (even within 15 minutes of driving after I've topped up. I will check it the next morning and there is no noticeable loss of coolant by then, but the light is still on MOST of the time... so... I think the light must be dead most of the time)
7) No leaks on the ground under the van
8) I looked for white residue indicitive of a leak on the engine somewhere... nothing I can see... [I'm not sure where the water pump is though. I tried looking everywhere, though]
9) Maybe I'm running a bit hotter than most people on this forum. The van temp gauge runs just under 215F when I'm going up and down hills in Colorado. Sometimes it might creep over that, but then the fan kicks on and it stays steady, even across the desert. Never overheats into the red. (We don't tow anything or have a lot of weight in the van because we are both very small people with small clothing.)
Is this something I can just ignore? It's not causing problems now, I guess, but... is it going to cause problems later?
I still get 26 mpg so long as I don't drive 80.... I have plenty of power... Most driving is highway miles. But we live in the van now, so... I'd like to solve it now if it's going to cause more problems later.
THANK YOU!
