No Heat in 1990 Honda Accord Dx
I am still trying to put my finger on why I have no heat. In the
summer months I was seeing lots of movement in the Temp display. So I
replaced the original radiator, and then the thermostat. All
fluctuations stopped, and it ran much cooler from then on.
Now I am seeing no heat. I wondered if the control valve was sticking,
as the "slide" for temp control resists staying all the way over to
heat. It "bounces" back toward the cold going no more than 3/4 the way
to the right (heat). Before I go and tear apart the dash to get to the
heater core, is there anything else that I can check? I did try
putting cardboard in front of the radiator to see if it is just running
too cold. There was some improvement, but still nothing like it used
to be.
I'm open to any suggestions, rather than to go see the dealership that
want's $1125.00 to replace the heater core.
Thanks,
Jeff

Start under the hood, and you may have to slip off the intake so you can
get at the water valve on the heater hose. If you don't mind LOTS of
heat just disconnect the control cable and put a cable tie or wire
around the 'tap' to hold it open.

I hope you used a authentic Honda Thermostat.(OEM)
Aftermarket ones are questionable,and you may get the wrong temp TS for
your vehicle.(on my Integra GSR;their cross-ref book said 180degF instead
of the proper 195degF TS)

You could have some crud blocking a hose (or that valve),maybe a backflush
is needed.
I believe the use of OEM HONDA antifreeze is also recommended instead of
aftermarket brands.
(IIRC,they allegedly cause early death of the new radiator)

Re: No Heat in 1990 Honda Accord Dx
Either your heater valve isnt functioning or the heater core is blocked.
Your turn to investigate which one is the problem

Re: No Heat in 1990 Honda Accord Dx
Either your heater valve isnt functioning or the heater core is blocked.
Your turn to investigate which one is the problem

Thanks to all of you who have answered my questions.
I have since checked the heater valve, and It does seem to be
functioning. I can visualize the valce opening and closing.
As for a question about the thermostat, I did not use a Honda OEM
thermostat, I used a new aftermarket 180F thermostat, but have been
unable to locate the documentation to identify if that is in fact the
correct set temp, or if it should have been 195F.
I am now wondering about the heater core, and wondering if there is an
easier way to backflush it, or test the flow through it. I imagine
that I can just disconnect the hoses and see if there is any flow or
not. Does this sound right? Also what type of flow (volume) am I to
expect? Low or high volume that should be circulating? I will be
trying to check these problems out in the next day or so, so any
further advice would be great.
Thanks again to all of you for your responses,
Jeff
