2000 honda civic changed hose but still leaking

Having changed the canister vac valve you may have a connecting hose leaking.

Check the:
- Fuel pump pressure and regulating valve.
- Check the ignition system.
- Air leaks. (Throttle body gasket, idle air control valve shucked open, PCV valve open, vacuum hoses, gasket intake manifold, A/C VSV).
- Muffler.

could very well be the water pump. they dont always leak if they are bad. sometimes the impeller that moves the water through the system fails.

The PGM Main relay is outboard of the glove box. You can see it if you get the glove box out of the way, but to remove it, you need to pop the triangular shaped plastic trim off of the end of the passenger side of your dash. The relay is held in place with one 10mm bolt and the electrical connector.

Over heating is usually caused by the thermostat being stuck in the closed position. Change the thermostat and this should solve the problem. Good luck to you

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.

Sounds like a blown coolant hose, or a faulty coolant water pump.

first off there should be one or two bolts on side or bottom if there is one remove then it will slide straight up. yes you want to clean it out with a house or in bath tube because it can cause plugs and other problems with new parts. let me know how it goes any more que. get back to me.

should be 80 to90 thousand miles ck with dealer

well if the hose you saying is leaking is the draft hose (the one that comes from plastic tank to the radiator) then you need to replace the radiator with a new one I have never found an sealing compund that will hold for more than a few miles the coolant is just to hot and the pressure to strong.

As far as you spring question there is no standard life expectancy, pretty much if the car drops heavy on that corner you should have it looked at.
Hope this helps
