you're interested in what is to be considered a temporary fix, read on.
Step 1: Clean the heck out of the cooling system - drain the radiator, fill with water and degreaser, run the motor until warm.
Step 2: Repeat 5 or 6 more times.
Step 3: Drain the radiator, fill with water only and run the motor until warm.
Step 4: Repeat 2 or 3 times. You must rinse the system with water until no degreaser is left inside, this is *very* important.
Step 5: When you are sure that the cooling system is very clean inside, refill with water plus two cans of Block Weld (no anti-freeze). Run the motor until warm (about 30 minutes). This hardens the Block Weld where the water is leaking into the motor. Do not rev the motor into high RPM during this process!
Step 6: Leave the motor off for a minimum of three hours
Step 7: Drive for 20-30 minutes in the local area to make sure that the repair has worked. Keep the RPM down! If successful, drain a small amount of water from the radiator and add some anti-freeze. If it's still leaking water into the engine, add another bottle of Block Weld and run the engine for 20-30 minutes. Let stand for three hours again. Test drive again.
Step 8: Drive
the car around like you used to... assuming that the process worked!
