Inexpensive Home Radiator Cleaning

With most local radiator repair shops now out of business (you can buy new radiators for modern vehicles much less than repairing the originals) finding repairs for original brass radiators is very difficult. Shops repairing large commercial truck radiators still are needed but usually in only larger cities.

If your older GM original truck radiator does not leak but its cooling capacity has become limited (coolant boils on most uphill drives) there is a successful home repair.

Solution: Fill your calcium clogged radiator with 50% “white vinegar” and 50% water and let set 2 to 3 days. You will be amazed at what comes out of the core when it is drained!  It even cleans the engine block and head!

This old school method has been a proven success over the years and it is very inexpensive. Check your local grocery store.  Price is about $2.50/ gallon.

Radiator shops usually use long small diameter brushes to “rod out” the calcium build up in the tubes. If they puncture a cooling tube with fins, they block it off with solder, and also solder the upper and lower tanks back in place.  You will never know how many have been soldered shut.  Their new black paint covers the evidence!

Save your cooling tubes with fins. White vinegar is the way to go!
