You should be able to, so yes. If you have a coolant leak the pressure will build and slowly decrease or it will not get to the correct pressure. Unless the leak is in the radiator cap itself as the pressure tester generally uses a different cap.

CHECK ENGINE OIL LEVEL SHOULD BE ON THE FULL MARK ON ENGINE DIP STICK. IF OIL LEVEL IS LOW.LOOK FOR OIL LEAKS UNDERNEATH CAR.IF ENGINE NOT LEAKING OIL CHECK OIL PRESSURE SHOULD BE 22 PSI @ 900 RPM IF NOT OIL PUMP FAULTY OR YOU HAVE WORN ENGINE BEARINGS.IF OIL PRESSURE OKAY YOU COULD HAVE FAULTY OIL PRESSURE SENDING UNIT. CHECK COOLING FAN TO SEE IF CAR COOLING FANS RUNNING WHILE ENGINE OVERHEATING.IF NO CHECK COOLING FANS RELAY AND FUSE IF ALL IS GOOD ENGINE COOLANT TEMPERATURE SENSOR FAULTY. IF COOLING FANS RUNNING WHILE ENGINE OVERHEATING.HAVE RADIATOR AND ENGINE FLUSHED OUT. REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.

I have a 1998 cadillac deville, that is over heating


check thermostat, put a coolant pressure tester to check for leaks. check radiator for fluid levels.
check to see if electric fan is working.
start car,when cooled, open radiator cap and check to see if its flowing,if not, then could be a bad water pump.
check carpet under dash for wet spots to indicate if heater core is bad.
any one of those could be at fault.

I own a 98 cadillac catera and


First check for any leakage from your radiator, hoses or overflow tank.

If it were a freeze plug you'd not be able to miss the puddling spillage. Where if it were a head gasket the coolant and fuel / oil would mix and you'd be driving a mobile smoke generator { very noticeable while smoke }

If you can't see the leak take it in for a coolant system pressure test. Which will pinpoint where your vehicle is losing coolant.

Car leaking coolant


First of all ensure that your car is leaking coolant fluid, and what is dripping is not just water condensation from the air conditioner.
If you have a coolant liquid leak, it can be from one of the ducts leading to radiator , from water pump or radiator itself. Check liquid levels, and if you have a leak have the car inspected by a qualified mechanic.
A broken water pump, for example, can cause your motor to blow in few miles.
