How do you pressure test a truck radiator - 2001 Dodge Ram 1500 Truck 2WD

NEXT STEP,HAVE A COMPLETE COOLING SYSTEM INSPECTION SERVICE PREFORMED AS FOLLOWS;
INSPECT COOLANT LEVEL,
TEST SPECIFIC GRAVITY,
PRESSURE TEST SYSTEM,
PRESSURE TEST RADIATOR/EXPANSION TANK CAP,
INSPECT DRIVE BELT(s),
INSPECT COOLANT HOSES,
INSPECT HEATER HOSES,
INSPECT BYPASS/MISC. COOLANT HOSES/PIPES,
TEST THERMOSTAT OPERATION,
INSPECT RADIATOR TEMPERATURE,
INSPECT RADIATOR COOLING FAN(s)/CLUTCH OPERATION,
INSPECT CONDENSER/AUXILARY COOLING FAN(s) OPERATION(s)
INSPECT RADIATOR & CONDENSER FOR DEBRI,
OBSERVE COOLANT TEMPERATURE GAUGE OPERATION,

check the following: 1.radiator fan motor and fuse for operation. 2. run cooling system pressure test for head gasket, hoses, water pump leaks. 3. pressure test radiator cap. If all tests pass, flush radiator with coolant flush or citric acid for 33-45 minutes

First things first....

disconnect the cooling fan switch start your engine the fan need start work if don't check your fuse and relay

I would begin by utilizing our shop's standard cooling system procedure.....

If the engine was stopped or you shut it down immediately then the possibility of damage would be remote as the piston would not be continuing to move which is where most damage occurs.. If the radiator failed a pressure test then the problem is that the radiator pressure was not high enough to prevent the boil. I will explain . Water boils at 100degrees c at 14psi (air pressure). When under pressure the boiling point goes up to well above the 100 degrees . If you have a coolant system leak the pressure will be at air pressure and when the engine is stopped the hot parts have not water circulation so the temperature goes well over the 100 degrees and so it blows off . 2 problems are present that you have to correct. Find the leak and have it fixed and secondly check that the cooling fans are working correctly. Caps come in varied pressure ratings for the radiator construction so check that the cap reading is suitable for you vehicle

You need this tool to pressure test the cooling system.

Could be either. Or it could be a hose. Take to any radiator shop and have your system pressure checked. If no radiator shop in your area, take to a trusted repair shop and ask them to do a pressure test for you. A pressure test is a device you put on your radiator in place of the cap. They are then able to pump up the pressure and visually check for leaks.

You will need to start by doing a radiator pressure test using a radiator pressure tester first verify that the fans are coming on when it gets hot if so then you will need to pressure test it find out where the leak is if there is no apparent leak but the pressure drops fast could indicate a bad head gasket. You can verify that by doing a compression test or a chemical test
