Advice on coolant leak
I have a 1994 Ford Ranger with close to 220,000 miles. It overheated about 6 months ago, took it to the mechanic who changed the water pump. Has been running ok since, but took it in to get the oil changed and another mechanic said it is leaking coolant from the timing chain cover as well! I notice reading here that this is not uncommon! I am hesitant to put more money into repairs as the truck is gettting up there in years and mileage. I'm wondering if I just put in a gallon of antifreeze a month, will this suffice, or am I risking major damage? Any thoughts?
