got a coolant leak from the bottom of the radiator on my 94 3.0 ranger with 164,000 miles on her.

bought a bottle of that leak stuff? how good is this stuff?

would cost about $147 for new radiator, hoses and clamps, and then a couple gallons of coolant also.

 

id buy a new radiator! ive always worried about stop leak gumming up the coolant passage ways in the motor and or the thermostat but i know people thats used it before and it worked.

 

Your decision depends on how long you plan on keeping the truck, buy a used one maybe, I don't think I would spend the money on a new one with so many miles already on the truck!! As far as I know the stuff works, never heard anything about it, I know you can temporarily clog it with an egg!!
