When you do a coolant system pressure check and there are no leaks why is the car still losing coolant?

Obviously, you are losing coolant from some part of the system. Did you do a pressure check or did you simply do a visual inspection? Coolant may be lost by evaporation or you may have a gasket leak which would allow coolant to transfer to the engine oil.
Check the oil dipstick after the car has run long enough to get it to an operating temperature where the thermostat has opened up. If the oil looks foamy, I would do a cylinder pressure check. If the values you get are more than 10 pounds different, I would suspect you have a blown head gasket.

Losing water Mazda 626?
Have system pressure tested at local shop unless the problem is obvious. Check coolant lines (upper and lower) to see if they are leaking. Check radiator for leaks. Water pump may be leaking. Also head gasket could be letting coolant in to oil. Pressure testing will check all these components
I can't find coolant leak but am still losing coolant on my Chevy where would I look?
Losing coolant in a vehicle is not a good thing. It is best to check all seals and all bends in tubing.
Can performing a pressure check for leaks in coolant system cause a crack in my radiator pleas help?
No, the system is only checked at normal operating pressure.No, the system is only checked at normal operating pressure.
How do you check the coolant level on a 2002 buick rendezvous?
There are marks on the side of the coolant reservoir that indicates the proper level. Keep it filled at all times if you are losing coolant you may have a leaking hose or may be your Lower intake gasket. you should not ever have to add coolant to your system.
Water and coolant empty and over heat on 2000 town and country Chrysler?
Have the cooling system pressure tested and check for leaks.
How do you fix an antifreeze leak in a 2006 charger?
You need to pressure check the coolant system to determine just what is leaking first and the address that problem..........
Will the check engine light come on if the heater core bad?
not likely. you will more than likely have a coolant leak in the car that ends up with coolant on the passenger floor. pressure test the system and look a for leak. the only way the check engine light would come on is if it had a coolant pressure sensor. most cars don't, only sweet expensive rides
Losing antifreeze but no leak?
check your oil to see if you have coolant in it. if you do your intake gasket needs changed.
Your coolant system builds up great pressure you have put a new water pump on as well as a radiator Yet there's still enough pressure to prevent you from opening the coolant bottle of your Ford Escort?
The radiator cap when bad will allow pressure to go back to the overflow bottle, after that check your thermostat. The coolant system should be pressurized when warm, so much so that the hoses feel hard when squeezed. The radiator cap is made to release the pressure when it becomes too great, if your cap is worn out the pressure will release too early and pressure will blow out to the coolant bottle.
Where is the air conditioning coolant refill port located on a 1998 Chevy blazer?
There are two schrader / port valves to the air conditioning system. One will be a high pressure and the other will be a low pressure. You need a certified mechanic to check and refill the system. You can not simply refill the system.
Why 1994 Legend RPM keep jumping up and down when at park only Could it be Idle control sensor?
Check the Coolant system, there is a coolant temp sensor that will cause the engine to do this if it is not actually in contact with the coolant. You will need to vacuum drain the coolant, refill then bleed all the air out of the system. On my legend this happened until realized the radiator cap was bad, it had lost it's seal so the coolant system lost pressure. I didn't realize because the coolant reservoir was full, but there was no pressure to pull the coolant through the system. It could possibly be the idle speed motor needing to be cleaned as well. Once I cleaned mine I haven't had any problems ever since.
Why is the truck dripping water near the gas petal?
Possibly ruptured heater core. if you are losing coolant-check it out.
