Cooling system pressure testing is a diagnostic procedure used to find coolant leaks that may not be visible during a simple visual inspection. A specialized pressure tester is attached to the radiator or coolant reservoir and pumps the system to its rated pressure. Any leak in the system, whether at a hose, gasket, radiator, water pump, or heater core, will reveal itself as the pressurized coolant seeps from the failure point.
Many coolant leaks only occur when the system is hot and pressurized during normal driving, making them difficult to find with the engine cold. Pressure testing simulates this condition without running the engine, allowing us to safely inspect every component. At Clutch Auto Repair in North Spokane, we also perform a radiator cap pressure test to ensure the cap maintains proper system pressure.
Spokane's temperature extremes stress cooling system components through constant expansion and contraction. A pressure test is the most reliable way to identify the source of coolant loss, whether it is an obvious drip or a mysterious drop in the reservoir level. If you are adding coolant regularly or see signs of a leak, a pressure test will find it. Call (509) 487-0161 for a quote.
What to Expect from Cooling System Pressure Testing
- 1
Radiator Cap Test
The radiator cap is tested to verify it holds and releases pressure at the correct specification.
- 2
System Pressurization
A pressure tester is connected and the cooling system is pressurized to the manufacturer's rated pressure.
- 3
Leak Inspection
All cooling system components, including hoses, gaskets, the radiator, water pump, and heater core connections, are inspected for leaks.

Results and Recommendation
We report the leak source and provide a clear repair estimate. If no external leak is found, we test for internal leaks such as a head gasket failure.
When You Might Need Cooling System Pressure Testing
- Coolant level drops over time without visible puddles
- Sweet smell of coolant but no visible leak
- Engine overheats intermittently with no obvious cause
- White residue or dried coolant around hose clamps or gaskets
