2008 Civic Ex won't heat up
Took civic in had the cooling system flushed and thermostat replaced. Now it won't heat up. When stitting at idle will eventually get to 9 bars then as soon as start driving it will drop down to 5, 3, then 1 or 2. The top hose stays hard like a lot of pressure is building and bottom hose is pliable. Took it back and after 2 more thermostats (last one Honda original) a dye test, pressure test nothing same results. I'm lost and so is mechanic. Could this be the water pump? It does circulate when checked sitting in shop. This a one owner car and the first time it has had the coolant changed (85,000 mi). Help!
