    I just bought my first Ranger. It’s a 2000 Xlt 2 wheel drive and I love it. I took it and had my mechanic look at it and he said someone had put stop leak in the radiator. He recommends me to put a new radiator in the truck . I’ve drove the truck about 100 mi has not run hot or anything. What are your thoughts any input appreciated. Thanks

    Those stop leak are bad news... It will clog up the pores and your heater core. Although, if it doesn't do any harm. I would just drive it. If you replace new radiator, new hoses (upper and lower) will need to be replace as well as thermostat and/or new heater core. This will get pretty pricy..
