I drive a 2003 Jeep Liberty with 151,000 miles on it. Since this problem concerns my cooling system, I’ll give you some background info:
I bought the car with 83K. Have done coolant changes at 90K, 120K, and 150K. The last service was done immediately after my water pump crapped out. I had a new water pump installed and had the cooling system completely flushed and refilled with Mopar HOAT coolant (per manufacturer’s specs).
Today, I brought the jeep in to have the spark plugs replaced and have some warped brake rotors replaced. My mechanic told me that he also found a small crack in my radiator. He said it was near the top of it. I can see evidence of fluid squirting onto the upper radiator hose - there’s some white residue on there. There are no cracks in the hose itself. Just the one my mechanic found near the top of the radiator itself.
Here’s my question. I’m due for an oil change in 2000 miles. I’m wondering if I can wait until the oil change is due to have him replace the radiator. Would it be smart to just buy a jug of coolant and keep an eye on the level in my reservoir and top it off with a 50/50 mix of coolant and distilled water as needed? Or should I go ahead and just have him do the radiator ASAP? I drive about 30 highway miles round trip to and from work every day.
I realize that to some degree this is crap shoot - nobody can predict the future. Just curious as to what you folks would do if you were in my position.
Thank you in advance for your assistance.
