My 2008 Civic developed same symptoms. I am pretty certain it is the compressor clutch. I examined the compressor and noticed that the clutch on the front was rusty. Not scaley but brown. I downed the clutch assembly with WD 40. Worked. Maybe a short term fix but I'm not hot for the time being. If you try this don't spray on the belt nor the alternator fan.

You can compensate for decking loss with a thicker gasket, and there are many on the market for Honda engines (esp the b Series). I can't say how well they hold up tho, but I know people who have successfully used them in Frankenstein builds (b18b bottom with bseries vtec head) with a fair amount of boost, and they seem to do fine, and they are also ...

The pressure generated at Top Dead Center on the Power stroke is very high. A "taller" gasket will have a larger cross-sectional area exposed to this pressure, so high "pounds/sq inch" grows proportionately as the area increases. Even the best Multi Layer Steel head gaskets are not designed to be part of the cylinder, just to seal the head to the block. ...

The main reason that I use D3 is to hold the car in a lower gear while I squeal the tires taking some corners at 9/10s. D3 is also for when you want your car to remain 'on boil' while you wring its neck. For those who enjoy a car that handles well Hondas are a great choice.

The A/C compressor has a clutch that engages when the A/C needs to run. It could be that the clutch/compressor is bad. You can verify this by looking at the end of the A/C compressor: within the pully wheel there is a disc that moves independently of the pully. I believe it should rotate most of the time when the system is cooling.

could be the high pressure sensor of your a/c when turned on the pressure in your a/c system builds up towards a couple of bar and then the sensor kicks in, because the pressure is too high. is your airco fan spinning? when stationary the fan should be starting after a minute or so. had the same problem on my golf mk4

Double check everything. If you can power the S terminal on the starter and get the car to start than it's on the other side of the circuit. Pull the relay again and make sure when someone presses the clutch the relay coil is grounded. Check your fuses, the relay should have power on two pins, one that powers the relay coil while cranking and one that ...

The fact that the fan comes on when the switch is jumped is very useful since this tests the power source, relays and fan motor. The fans can be activated by either the switch in the water passage near the thermostat housing or the coolant temperature sensor via the PCM (powertrain control module) located in the cylinder head below the distributor. So ...

Best recommendation: Purchase a $30 Haynes or Chilton repair manual from your local autoparts store. Best money spent ever. Then follow the troubleshooting guide in your book for "poor cooling". If indeed shorting out that Engine Coolant Temperature (ECT) switch starts the fan and it never works otherwise, then the switch probably needs replacing. ...

Lead-acid batteries contain a solution of sulfuric acid (H2SO4) and water -- the solution is referred to as the battery's electrolyte. Adding a solute (in this case, H2SO4) to a solvent (in this case, H2O) will lower the freezing point of a solution. A fully charged battery has more H2SO4 than a discharged battery. The additional H2SO4 depresses the freezing ...
