coolant res holds pressure great but still losing a ton of coolant
I have a 98 S70 GLT and i am leaking a ton of coolant. I found that I had a crach in the res where the return hose connects so i puut on a new res and cap.
I pumped it to 4psi and it hasnt lost any pressure in the past 40 minutes. i still have the pressure tester on there as i type this
Any ideas? I took the belt guard off and the water pump didnt seem to be leaking (i only popped off the plastic guard right bty the coolant res.

I can't tell for sure what sort of fluid that is in your pictures - the locations and overall appearance don't make me think "antifreeze!" however.
Whenever an S70 is losing fluid (and there isn't a puddle under the car) I suggest that you start feeling the carpet and sniffing your defroster vents.
Then pull your dipstick and see if your oil has been fraternizing with coolant.

I did check the heating core and that was fine, also there is no fluid under my carpets
I do sometimes smell antifreeze when the heat is on (havent had the A/C on since the leak stated) but that is (i think) because the steam from the antifreeze gets sucked into the vents
i don't know where to look now

I was worried about pumping the res too high. Are you sure 15psi though? that seems high, i thought 150kilograms/sq meter (what it says on green cap) was ~3.1 psi? i was worried to pump it to even 4psi

Also it doesn't take much fluid to make a huge mess under the car. When you pressurize the coolant tank look everywhere. You are pressurizing the entire system not just the tank. If you pump it up to 11-15 psi and it drops quickly and you don't find the fluid it could be going in the oil or the cylinders.

Also want to pressure test a cold engine; will naturally lose pressure as the engine cools. And 40 minutes is nada.
Pump it up to 15 psi on cold engine and let it sit overnight; if your pressure has dropped by the AM and you don't see any puddles under the car or in the cabin, pull the plugs and crank the engine over to see which hole makes like a geyser..
