Here's another strange twist to all these problems. Last night, her radiator light went on, and this morning there was a pool of fluid under her car. The water pump was thoroughly checked, and there seems to be absolutely no problem from my installation, though the problem is concentrated in that area. What kind of a problem (other than wear and tear) could make a water pump blow? I get the feeling maybe these two problems are actually unrelated. As far as the secondaries go, where are they located and how do I play with them? THanks a lot.
