Is it safe to drive with a cracked radiator?

Answer 1

Carefully monitor the temperature gauge and top of with coolant and water then short distance and slow driving may be. Long and hilly road may be a problem. Bring extra 2-3 gallon of water in case the radiator overheated. Coolant may cost $6-$9/gallon. New radiator starting from $70. So do the math and see which way is more economical to resolve.

Or Temporarily Fix:

== * Ground black pepper * Duct Tape Step 1:

Find the location of the leak and decide how bad it is. If the leak is coming from hose, patch it with duct tape. It will hold for about a week or until you can get a replacement hose. If coolant is gushing out of the radiator and there's a big puddle around your car, rethink going to work. Step 2:

Remove the radiator cap and add about a teaspoon or two of ground black pepper, if the leak is in the radiator itself. The pepper lodges in the hole and swells when the water hits it, expanding to fill the hole. Step 3:

Close the radiator cap and fill the overflow container to the proper level. Step 4:

Bring extra pepper in the car with you, as well as a jug or two of water. You may have to add additional pepper or water to the radiator. Make certain that it is cool before removing the cap. Step 5:

Schedule an appointment with your mechanic if necessary. Be certain to tell him what temporary measures you took.
