I have only bout 2800 miles on my trk now and I notice that the resevoir is down about a 1/4" below the min mark. I know that it was at the max level a while back. Is this normal? Maybe has something to do with the extreme temp changes outside???

 

When the engine is completely cold and parked level, top it off with the proper coolant. Watch it for the next few days. Document your drving habits, styles and conditions. If the "loss" persists then you have clear documentation for them to track down and fix the problem.

Temp changes can affect fluids but not to that degree, I would think.

 

chk all the stupid hose clamps for cracks ! I had the lower rad hose crack and puke the coolant out
also chk that the heater core hoses are not leaking onto the area of the coilpack and intake manifold an evaporating,small drips !

as monsta said if it persist take it in !

Just for a point of reference, my coolant was down also about 1/4 inch on my 5.4, but that after 28,000 miles, not 2800. Keep an eye on it.

 

Thanks guys. I'll be keepin a close look on this. Will let ya know what develops.

 

I can't add more than what's been said above, just to

1) check it each day when completely cold as Monsta said, and mark the level on the
reservoir with a black marker or such, and

2) check all hoses/clamps for leaks as pointed out by Forty (I like to take a stick of my kids'
sidewalk chalk and draw all around the suspected culprit clamps, that
way any small leak is easily seen when the chalk is swept away by
the fluid; this trick doesn't fare well if it's been raining out or you go
a swampin' in some big puddles!)

Let us know if anything turns up.... <3K miles shouldn't have a
drop that fast IMO

done lurking. great site.
there is a recall or tsb on radiator hose clamp failure.
came home one day to see the idle x just dripping coolant from the lower hose clamp area.

 

I check mine weekly and this last check mine was down also , pretty much the same amount. T his is the first time it was down. No visible leaks.

in my experience when it gets cold, one has to tighten hose clamps sometimes as they tend to leak,hopefully thats all it is.

 

actually it is the lower radiator hose clamp. That is where it is leaking. I squeezed it and it broke in two pieces. I replaced it with a screw type clamp.

Definitely keep an eye on it... but don't worry too much about a small "loss" if you find no leaks. More than likely just coolant displacing an air pocket that finally escaped from the system.

 

I filled it back up about a wk ago now and it hasn't gone done noticeably since. It took about 1-1.5 qt to get it back to the cold fill mark. So far, so good.
