My car smoke and run hot a1994 honda civic

SOURCE: 94 civic erratic idle when warm

either low coolant or your IAC motor is acting up

SOURCE: No Heat In My Honda Civic.

I do not know the history of your 94 civic as far as mileage, how well the car has been maintained or not maintained. Could be a block within one of your heater hoses, the valve that open and closes to allow the radiator fluid through your heater core to recirculate the water, or a block within your heater core from rust deposits and or lack of servicing your radiator fluid could cause a build-up of deposits. You might have an air lock within your cooling system" air pockets". Perhaps you can purge your coolant system to allow any air bubbles or pockets that may have entered the cooling system when adding coolant, replacing a radiator, or simply servicing the coolant system. Make sure you have the proper radiator cap to produce the proper amount of pressure with your cooling system. Check for any fluid leaks in your cooling system as well. This may allow air into your cooling sytem.

SOURCE: I need instructions on how to replace rear wheel bearings on my 1994 Honda Civic

Bearings are pressed into the hubs...much easier, faster and economical (if you don't have a press) to replace the complete bearing/hub assembly, no pressing is needed, since bearings are already pressed into the new hubs. Cost..aprox, 60 buxs each.
Here are the steps for the rear replacement...
Loosen the lug nuts on a rear wheel. 2) Chock the wheels and jack the rear of the car on the side with the lug nuts that you just loosened. 3) Remove the wheel by removing the lug nuts. 4) Pry open the dust cap covering the center of the axle/spindle. A small screwdriver tapped into the space between the hub and dust cap will work well for this. 5) With the dust cap now removed, use a thin center punch to straighten the little dent in the rim of the spindle nut so that you will be able to turn it freely in the next step. 6) Use a 32mm socket and a large breaker-bar to loosen the spindle nut. Unscrew the nut all the way and place it in a clean, safe area. 7) You should now be able to slide the hub/bearing assembly from the shaft. 8) Installation is the reverse of removal. Use plenty of high-temperature wheel bearing grease on all surfaces before you mount the replacement hub assembly.

IMPORTANT: Torque the spindle nut to 134 ft/lbs....(per manual specs)

When reinstalling the dust caps, tap them gently into place to avoid denting them...Install wheels, jack her down and pat yourself on the back...job complete.
Good luck..hope this will fixya up...please take time to leave me a fixya rateing...

Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

Testimonial: "thank you for the very clear, step by step instructions for diagnose and remedy"
