Heater hose on 1989 Honda Accord

I'm trying to replace a failed heater hose on my 89 Accord (I think it's a heater hose. It's about 8" long, and connected to the water pump) Anyway, I got the back clamp off but the one on the water pump is a spring type and there isn't enough room to put a pliers on it. I know something more should be removed to open up that area, but I don't know what most of those are, and everything is old and looks pretty fragile. I just need to know the best (and easiest) way to remove that upper clamp. Thanks Guys!

Need to replace heater core

Very very big job. Only do this if you really really love your car. Here is the 100ft overview:

*Disconnect the heater hoses at the heater core inside the engine compartment. (recommend cutting the hoses and replacing with new ones)
*Disconnect the heater valve cable from the heater valve
*Remove dashboard (involves removing steering wheel/column, radio, glove comp, etc)
*Remove the heater assembly (big black plastic box behind the radio)

The core is inside the heater assembly.

Again, this is a big job, and it will probably be very frustrating at times (I know from experience). If you do not have a repair manual for the car and you think you want to try this...get the manual first!

1989 honda accord DX My radio and heater motor both quit working at the same time, I checked the fuses and even changed the wiring harness on the ignition,and neither one work,please HELP

I am currently working on the same problem, I think you will find that with the car running, if you turn the ignition off very very slowly there is a spot about half a millimeter before the engine shuts off that the heater and radio will work. but it won't stay there. let me know if this is the same problem.

1996 honda accord, replaced radiator and is still leaking in same spot. radiator and hoses are all new now and is still leaking from down the transmission. there is also a hose that no one can see where it...

The only other long hoses on that engine that I can think of, that might leak coolant, are the two heater hoses that run to the heater core, through the firewall. They do run right above the transmission, and might just be the source of your leak.

89 Accord LXI Idle problems

It's fuel infected and it has a vacuum leak, most likely a PCV valve that is stuck open, I've seen a few now. Replace the PCV valve 1st, if that doesn't fix it, start looking for a hose that has come off.

Heater hose is leaking on 97 Honda Accord

Put your car on jackstands then identify the hoses. They will be going into the firewall as a pair near the center of the car.

Because of the **** conditions, I would suggest taking it to a mechanic.

89 Honda Accord Heater doesn't blow air at all

sounds like the blower motor, Get a test light and hook it up to the wires going to the motor this will tell you if power is getting to the motor . Hopfully it is , Just pull the panel off on the pasangers side under the dash and you can see the motor . It's easy to change and should fix the problem. If you get no power it check for power at the switch on the dash . It could have gone bad !!

Replace heater core for Honda Accord 1992 LX 2.2L

It's probably the valve in the cooling hose that lets coolant flow into your heater core. This is up against the firewall about 3/4 of the way down on the passenger side. When you switch the knob from warm to cool, you should be able to see the little "arm" on the hose move back and forth. You may need someone else to watch as you move the temperature knob back and forth.

Also, watch out for over heating (not due to the valve), because it could mean that you could need to replace your water pump and/or thermostat in the near future. If you haven't replaced your timing belt recently (or if you have) and didn't change the water pump at the same time (Honda recommended) Your water pump could be failing.

Odds are pretty good though that it's just where the cable connects to the valve. It may have rusted over time and stuck, or broke the end of the cable, or just need lubricating/bending back into place.

If this is not the case, then you may just have a clogged heater core and should have your coolant system thoroughally flushed in the near future. If none of these work, you may need to replace your heater core.

Drop me a line when you check these over and I'll see what I can come up with.
