Car Forum / Honda Cars / March 20071977 CiViC loses coolant
Hi, My bunky is an old '77 Civic 2-door with the blue smoke option pack. It appears to be losing coolant and boils after a short time, but there are no visible cooling system leaks. My guess is that it's a corroded aluminium head issue and the leak is into one of the cylinders. In that case it's pretty much a terminal situation for such an old engine. Does that sound right, or am I overlooking something less serious and maybe repairable? Regards, Murray R. Van Luyn.

Does that sound right, or am I overlooking > something less serious and maybe repairable? I had a '78 Accord which had a pin hole leak in the water jacket in the intake manifold. This leak produced white smoke and over a period of time it eventually caused the head gasket to fail. Upon removing the intake manifold, there was a distinct line of dried up white antifreeze residue running down the inside of one of the intake runners. Pressure testing the manifold's water jacket with compressed air in a sink of water confirmed the leak, air bubbles came out through aluminum runner. Eric Hi Eric, Thanks for relating your experience. I haven't seen any white smoke from my exhaust as you had encountered, but it's been running very rough for a few minutes after start-up. I guess aluminium heads and manifolds just have a finite lifetime in terms of coolant vulnerability. Probably time I started looking for a replacement. I wonder if these Honda Jazz sedans are much good? Regards, Murray R. Van Luyn.

Seems there are a few things I need to consider. I know the electric thermatic fan doesn't work, but it hardly ever came on except at traffic lights when it was working. Maybe I should investigate that further, take a more serious look at the the thermostat, check the timing, and then ultimately see about some form of pressure test. Gee, I hope it is something simple. I've been nursing the poor old thing for years now, and I would hate to ever see it put down. Regards, Murray R. Van Luyn.
