Engine worn out? Oil and Coolant consumption


Asked by Oct 09, 2013 at 05:40 PM about the 2005 Chevrolet Suburban LT 2500 4WD

Question type: Maintenance & Repair

My 2005 Suburban has been using about a quart of oil every oil change. Recently, I
noticed the temp gauge going up at idle and returns to normal when driving. I checked
the coolant reservoir and it was empty! I put a gallon of new coolant in it and so far it
remains at a good temp. There is no milky gunk under the oil fill cap, the oil on the
dipstick is a nice dark brown/ black, no smoke from the tail. Are these just signs the
engine is worn out? It runs great!

Using a quart every oil change is considered "normal" if you have some miles on your SUV. Check it every so often and top off when needed. Keep an eye on the coolant reservoir, you have a leak somewhere. The reason the temp gauge was going up was that you were low on coolant. After you drive it somewhere and it is warmed up and park, open the hood and look around. Check the hoses, water pump, radiator, etc. for signs of coolant. You also can proabbly smell it too.

It has 163,000 miles on it. I can smell antifreeze at times. I was worried about a head gasket or other catastrophic things


Find the leak first and address it. Hope for the best.
