Well nights. I would like to ask for help please. I have a 3RZ-FE Toyota, I changed the plastic radiator lid with an aluminum one. The problem what I have that the system is not releasing the pressure tank ... first I had a lid of 0.9 with 12LIB almost new I thought it was wrong, then bought another of 1.1 of 15lib ... when I put it I performed a test and when he heated to the engine I was dripping the liquid like this to the deposit but 2 days left the car stop (radiator liquid) The handles are like the stone and it starts to throw liquid by the rubber joints (by the pressure) ... the engine does not warm the thermostat /pump it works well but I cannot understand that this problem is causing me. Let's say what I do I hope that the water warms up in the system and I also take out the lid to release pressure, hill and I walk well, but once it starts cooling the engine I have to repeat and lose a lot of liquid ... please someone would have any idea that can cause this strange problem?
