The first test, quite likely you didn't have a good seal on the radiator adapter. Alternatively, test it again and overpressurize it a bit this time, pump it up closer to 20, if you have a leak you'll see it pissing out somewhere and the PSI drop will be faster.
Hi everyone, I have just replaced a leaking thermostat seal and did a coolant pressure test. After about 5 minutes, pressure remains the same at 20 psi but after about 15-20 min I lose . Go to the pressure that is on the cap. Should hold that pressure all day long but 15 to 20 mins should be fine. Looks like in the pic your leaking where at the seal on the pressure .

With the engine off, the water pump is off and can’t circulate the hotter engine coolant away from the engine. There is no air running past the radiator when the car is parked either which means the heat is being retained for longer. Any heat within the coolant system will cause pressure. That’s why your car needs to be completely cold .
I don't recommend any "cooling system sealer." Find the leak and fix it. And why do you want to pull the heads when the block tester was negative? As I noted above, we did the coolant system pressure tester but we didn't use a stethoscope and its a 2003 Ford Explorer 4x4 V8 4.6 liter. The oil looks normal.Coolant pump seal leaking. The coolant pump has a seal which prevents coolant from leaking past the bearing. If this seal fails then coolant can seep out where the coolant pump pulley shaft enters the pump housing.

We do not recommend using Steel Seal with long life / extended antifreeze .
If you want to find a coolant leak or test the pressure of the cooling system after a coolant flush, you can perform a radiator pressure test, also known as a coolant pressure test. The test requires connecting the pressure tester to the coolant reservoir or the radiator and pumping the tester to pressurize the system, which can help find coolant leaks.
The first test, quite likely you didn't have a good seal on the radiator adapter. Alternatively, test it again and overpressurize it a bit this time, pump it up closer to 20, if you have a leak you'll see it pissing out somewhere and the PSI drop will be faster. 2.

The thermostat seal was split in multiple places, and I thought that was the problem originally. I want to clarify the. A cooling system pressure tester is used to pressurize a cooling system and hold it at a specified pressure while looking for leaks. Coolant leaks can be internal (i.e.: head gasket) or external (i.e.: radiator). It is important to take these things into consideration when looking for a coolant leak.
Went to pull a vacuum, and cannot get below 18000 microns. As far as I know, this is the first time the system has been evacuated since installation 5 years ago. The system held at 18000 microns for a couple hours, indicating that the system was sealed but moisture was present, so we shot nitrogen through and put the vacuum pumps back on. Checked hoses etc but I can't see anything. Car makes a sizzling noise under the bonnet when I switch engine off and get out car I can hear it.

Once you’re convinced the engine and cooling system are back to ambient temperature, .OTC's Cooling System Pressure Tester allows you to pressure test the cooling system on most cars, light trucks and SUVs. Also works on motorcycle, ATV, snowmobile, and many marine applications. The tester's universal fit design eliminates the need for multiple adapters. Note: will not work on Saturns, Kias or Jeeps with a plastic coolant reservoir. You can pressure test the whole cooling system with no battery connect: the heater valve is opened with no electrical current. Even with air inside, pump the tester to 29 psi and the whole system will be under t=29 psi everywhere regardless Tstat closed or opened (there is a small bleeding on Tstat anyway).

If you pressurize your system which is coolant and gas under pressure. If you loose 1 oz of coolant gas will expand into this 1 oz volume, and this will not affect pressure by much... You will most likely see this 1 oz by your eyes.. If you drain coolant system and pressurize it with gas, you have much better chance to find your leak.. The find it all trick for coolant leaks. Remove all coolant from the system. Apply shop air at the psi of the system. The psi is written on the cap normally. Spray everything you can get to on the coolant system with soapy water I suggest 60% dawn dish washing soap and 40% water. Hoses, caps, etc. - a poor seal at the cap, either caused by the seal in the cap or a imperfection on the mating surface on the reservoir. - a hairline crack that isn't visible along the thread - cap is not operating properly and is venting pressure. (disproved with a new cap) - Overheating - head gasket is leaking causing excessive pressure in the coolant system.
