Should I do anything about small coolant leak

[Jim]

There are traces of coolant coming from a head gasket leak according
to the dealer who inspected the car. I've not yet had to add any
coolant, the radiator is full and the level in the overflow tank has
not dropped appreciably. I know there is some risk of clogging with
the various sealants. So the question is what would you do...or would
you do nothing at all until/unless the leak starts to require adding
coolant.

TIA

Hi,

Personally, I would do nothing if it only requires addition of a tiny
bit of coolant periodically. My dealer parts guy said a little seepage
is "normal" and you'll spend far more fixing it than buying some coolant
and topping off on occasion.

If you're worried about coolant loss, powdered Aluma-Seal has worked
well for me. I only start with about a quarter tube, and add more if
that doesn't do the trick (I think a full tube is good for something
like 22 qt/20 l.) I haven't had any clogging problems with it that I'm
aware of.

Best of luck,

Rick

I'm looking at same thing on wife's Nissan and taking it in Monday. I can't
find source but suspect water pump on old car.
Repair shop said we should not see any leakage. You haven't mentioned age of
yours.

In spite of what dealer told you and other suggestion that it is not a
problem, my wife insists on taking the Nissan in for repairs ;(

If any coolant leaks into your oil, it can really affect engine wear,
especially your bearings. I'd send your oil in for analysis at the next
change, just to be safe.

Between the 4 vehicles I own and 5 different vehicles I frequently drive at work, they all need the coolant and oil topped off once in a while.
Ignore it, do nothing!
