Got the car in my shop. Ran it awhile and found one heater hose totally cold. Blend door was working fine and coolant system was full. Temp gauge read right in the middle where it should be. So, obviously no flow, but why? In front, on top of the radiator is a plastic water manifold with three water connections. One end goes to the lower radiator hose. The other end has two hoses - one to the heater core and one to the engine block below the thermosat. All hoses were hot except the one to the heater core. So, I pulled the hoses off to see if there was any sort of blockage in that plastic manifold. Nope. It was clean. So, I put all back together and now? The heat works fine. Now I'm really perplexed. I fixed nothing. Seems maybe I might have purged some air out a hose when I removed?
Whatever the problem was, I'm sure it will happen again because I don't think I fixed anything. That water manifold was broken off it's mount and hanging down a couple of inches low. I remounted it on top where it should be, but I can't figure how that can make any difference.
