Radiator Flush What material is the best to flush a radiator and attempt to remove mineral scale. Years ago when the radiators were all metal you could soak is a caustic bath but with all the plastic on this radiator it may not be prudent. Removed the radiator to exchange the M42 engine. I want also to flush the replacement engine before putting in car. I removed the thermostat and water pump and found a some mineral scale especially on the water pump. Both will be replaced after flushing. One option is to use white vinegar but open to suggestions. |
