Is there a way to verify/test that there is no leak on the HG causing the cooling system to be pressurised?
I'm having a possible issue on my new build where the radiator resevoir bottle gets a lot of coolant pushed into it whenever I drive the car a bit hard. Now, I know someone's going to say it's normal for the level in the overflow bottle to rise due to water expanding when hot, but I want to be sure thgere is no problem.
Quick history that might be applicable.
What makes me uneasy is that the coolant level didnt' fluctuate before. And now it does. I guess it is possible taht the leak at the hose clamp allowed the system to depressurise slowly which caused the coolant never to push up into the resevoir. And the leak then progressed to the point where I noticed the water leak.
I'm yet to see how it reacts under hard driving. What is an acceptable level for the coolant to rise in the resevoir? AND, if it didn't suck back into the system once it cools down, what does that indicate?

- Motor was broken in and coolant NEVER altered from the "max" line on the resevoir.
- Motor was dyno'd and again, coolant level never changed.
- A few hundred miles later I got a big water leak, which turned out to be one of the coolant hoses behind the block that was rupturing where the hose clamp presses it. I fixed that and refilled the coolant system. Did not bleed it extensively, but figured I got rid of most air pockets.
- Took car for a 50mile drive with some hard revs etc. Got home and coolant bottle was about 80% full.
- Bled system completely using the FSM method. This morning did another 30 mile drive but not going over 5k rpm. Coolant level only rose about half and inch.
