So, after opening my resivoir cap and seeing no coolant, and then opening the radiator cap and having to strain my eyes to see coolant, I came to the conclusion that I was losing coolant .

I have filled the resivoir and radiator probably 4 times within the last 2-3 years. Its obviously going somewhere...no drips under car or anything...Heres whats puzzling......

1. No smoke from exhaust

2. Checked coolant in resivoir after driving and it is green just as when I put it in with no oily tint of any kind.

3. Pulled oil dip stick and oil wasn't milky or have any bubbles. Looked just as clean as when I put it in a couple thousand miles ago.

So I have a hard time believing that this could be head gasket related.

2 years ago I had the intake gasket replaced so I doubt its that.

Anybody have any ideas on what could be happening?
-As it sits I probably fill the resivoir a little every 4-5 months.

I can easily live with putting $5 of coolant in twice a year...I just want to make sure I dont damage the engine, or spin a bearing.

 

I got two suggestions ........

#1 ; Radiator/cooling system pressure test ..

And

#2 ; Check your front passenger's side carpet really well , as in lift it back from the firewall a bit and have a really good check in there for wetness . Sticky wetness . As in , Antifreeze Sticky wetness ...

 

What would the passenger side carpet suggest it would be? Hahah

 

heater core.

Look for leaky freeze plugs and check for leaks around the water pump.

 

Could have a very minor leak that evaporates on a hot engine before it ever hits the ground. Losing a little bit every few months is a pretty small leak. The recovery tank cap is vented, so eventually you will lose some water out of it as well.

 

Yea I think that this is probably the case...Cause its done it for the whole 3, almost 4 years I've had it and it hasn't gotten any worse. I guess I should be happy that its not at all severe. Thanks for the info guys!
