2 questions
a)high pressure is present when I check the level in my power steering reservoir. When I unscrew the cap strong pressure vents. I'm thinking the pressure relief valve may be going and the pump should be replaced.
b)I had my cooling system flushed recently and I seem to be constantly adding antifreeze. No leaks have been found and I'm not burning it either(head gasket). I'm wondering if the system wasn't bled properly and I've got air locks present. At times I can see the temperature gauge rise to the mid point at idle and then drop to the quarter mark and remain there when I'm driving.
