1977 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.

Re: 1977 CiViC loses coolant
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.

Re: 1977 CiViC loses coolant
| no visible cooling system leaks.
1 can put a big & thick rubber washer into radiator ( when cool ) cap's socket, use a 60 ml syringe to pump air into radiator to create pressure, then a leak can be noticeable if fluid is seen / felt @ any joint. www.aa1car.com/library/overheat.htm |
Re: 1977 CiViC loses coolant
Thanks for the link TE. 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.
