Hi all,
I have a 97 T-bird with the 4.6L sohc v-8.
during the past few colder months, I've noticed that the coolant level in my reservoir tank drops between half an inch to an inch below the "cold fill level" mark(on the reservoir tank) per about 1200 miles. (I check the level when motor was dead cold). I don't know weather this is normal or not.
Here are some facts which might help making your decision easier:
--low coolant light is not on.
--I can't see any coolant puddles/leakage anywhere.
--My oil level is normal, no oil usage.
--color of oil is normal(I think....)
--color of coolant also normal
--There are no symptoms of overheating, temp. gauge never goes above the middle,
BUT: I do notice that the car reaches normal operating temp. a lot quicker in the past months, although it's gotten COLDER outside.(this MAY be be due to the Arx engine cleaning I'm currently running in the engine),
--last time I had the coolant replaced (not power flushed) was about 7,000 miles ago.(thermostat was not changed)
--the motor has 90,000 miles.
--as I said, the drop in tank is: 1/2-1 inch/1200 miles.
What do you think is the cause for the drop?
where is the coolant going?
is it a leak that I can't see?
I'll be doing a UOA in a few months; would I be able to see what's happening..?
Would appreciate your comments/thoughts/help very much.
Thanks !
