Ok, my radiator hose that connects to the top of the radiator on the drivers side popped off yesterday. I was able to re-attach it and attempted to top off the coolant with 50/50 mix, this is where I got scared. I poured about 2/3 of a gallon of coolant in (not sure how much stayed in) and as I was pouring it in it was coming out of the reservoir overflow tube. No the engine was not cool...

So I took it to napa in the morning and they did a drain and fill adding a full gallon but there is nothing in the coolant reservoir.

Where is the coolant going?
Shouldn't there be visible coolant in the reservoir?

I have 91k on it I am late for my 90k service, the dealer does all my work.

 

When the hose popped off the radiator, did it overheat?

I have been helping a friend with his newly acquired D2 with an overheat problem (completely clogged radiator, and probable head gasket failure)...since I have had to refill and bleed his coolant system many times, I have learned to rotate the overflow tube 180 degrees (so it now points up) when filling the reservoir. This keeps improperly directed coolant from the bottle from going straight out the overflow tube.

If NAPA drained the coolant, you are going to need more than a gallon to refill it completely. From dry, the coolant system will take about 3 gallons.

Other than coolant from the reservoir overflow tube, is it leaking anywhere sle onto the ground?

 

You need to do a coolant pressure test before you toast your engine.
Also when you say your right upper radiator hose are you talking about the small hose that is attached to the nipple. If you broke that nipple, throw the radiator away, there is no safe long term repair other then a new radiator.

 

The water pump, if left with an open pipe, is capable of pumping about 2.6 gallons a minute at 1000 rpm. So it could make what little coolant remains behind join the rest on the pavement in record time when your break a hose. If you had NAPA shop do a drain and fill, and they just added a gallon, you are running with 4-5 quarts in a 13 quart system. If no coolant showing inside the coolant reserve bottle, that is sub-standard work IMHO.

Your engine is at severe risk of overheating. Without a real quantity of coolant, the space at the top of the engine, where the heat sensor is, will just have a cloud of steam in there. Your temp gauge won't read hot, because it is just steam. The water (coolant) is hotter. Example - you hold your hand over the pot of boiling pasta on the stove, pretty warm? Now stick your hand in the pot (get a quicker reaction) [don't try this at home kids].

Don't drive this truck unless you have coolant 50% fill in the coolant reserve container. I don't care if you put in 50/50 green premix coolant, or distilled water, etc. But have something in there for the system to work with.

There's no place for coolant to "hide." Water does not compress. Here's a flow chart of how it moves thru the system. Your's has too much air in it and not enough coolant.

You would not think the shop had done a proper oil drain and refill if they just put back in two quarts of oil. Same thing with coolant , needs to be properly filled. If shop drained your system, added only a gallon back, and let you leave.... I'd be looking for another shop and an attorney. Hope you paid with plastic so you get the credit card company to go to bat for you.

 

ok, it was my understanding that they added a full gallon in addition to what was in there, but I could be wrong... I will top it off and make an appointment to get it pressure tested.

 

No it did not overheat it was still reading in the safe zone on the temp gauge.

 

No there is no coolant on the ground, at home or at my job I check for fluid leaks regularly.

 

I am talking about the large diameter hose hose that crosses the radiator and attaches just above the the air box, the hose and the radiator checked out fine.

 

Hopefully just more air in system that needs to be purged out.

 

Why are you making an appointment to get a coolant pressure test done, you can rent the tester from a part store for free and test it in 15 minutes, why pay some one to do what you need to learn and do yourself?
