![]() ![]() My girlfriend has an '03 Civic that started overheating out of the blue. ![]() I plan to increase the head-bolt torque to 55-60 lbs/in., as some do, when I put it all back together this weekend. It also seems that most folks find a head gasket replacement fixes the problem. But, it seems that this engine (D17-A2) lasts forever until an eventual mystery coolant leak occurs. ![]() I was disappointed when I didn't find the obvious gasket burn through I had expected. I have it apart now and the gasket and head look pretty good for 175k. I eventually am doing a head-gasket replacement. Even when watching it in overheating mode, :sick: there were no obvious leaks. I would consistently lose a quart of water to work (45mi.) and again on the way back. Eventually, I replaced the radiator and the overflow bottle trying to find out where all my coolant/water was going. I replaced a sometimes failing A/C radiator fan, after replacing the thermostat and both old upper and lower hoses. I had a slowly progressing over-heating problem also. There is also no apparent wet spot inside the car and on the floor under the dash, where a leaking heater core would create that mess. Of course, I also went through an industrial area. I also smelled a bit of a chemical smell towards the end of the trip but not during it. I had checked the antifreeze levels before I left but haven't checked after because it is too dark. I took a 70 mile trip today, and then it began overheating when I got off the expressway. The overheating also seems to happen in the pauses after long trips. Leak sealant seems to have helped the problem before, but I am not sure it is now. I've noticed the heater stops working a few days before the engine begins to overheat (so I put in coolant). The leak loses antifreeze over months but seems to be speeding up. They've let the engine cool for about 5 hours and pressure tested it. They've tested the oil for any traces of coolant. They've replaced the thermostat, the hoses connecting the radiator and the radiator cap. The problem is, I and two mechanics cannot find it. Since fall I have had a progressively worsening coolant leak. ![]()
