It certainly could be right. For one thing, this group has
many reports of Honda radiator failures for a Honda this
old. For another, the loss of coolant would mean certain
engine control sensors are not being properly cooled etc.
and so are not operating correctly to control things like
engine idle.

You can google the two Usenet Honda groups for info on
action to take to replace a radiator. Repairs (in lieu of
replacement) are generally not recommended for someone in
need of a reliable car and not doing the work him/herself.

Honda service manager just called and said the rad was toast
due to
leaking at the bottom and all the other problems were
related.

does that sound right to anyone?

Replace the thermostat. With a dealer one.

Change the coolant while you're at it, not neglecting to turn on the heater
and remove the block drain. And use dealer antifreeze.

Hi, I have a 93 Civic EX 4 door(Auto) 1.5L L4 FI  with the following
problems...
It has 360,000 kms  has had regular suggested maintenance done by honda
dealer.
Original owner.

Revs high at startup then idles up and down after 5 mins(warmed up)
After driving at 60km/hr it overheats(10 mins of driving)
Rad Fan doesn't come on.
appears to be leaking coolant from bottom of radiator near/at hose on
right passenger side
Top rad hose is warm and the bottom rad hose cool
Collant level is getting high in resivoir tank
Coolant level now is not visable in the radiator(it was yesterday)

Coolant does not appear to have oil in it
no visable bubbles in the coolant resivoir tank
Oil does not smell sweet
exaust color seems normal but there is a sulfur smell.

I was thinking thermostat at first but then the idle problem confused
me.

any idea's?

thank you

Greg
