I have a 1994 Honda Accord EX. Two Days ago, my upper radiator hose
blew while i was driving. I immediately stopped when i noticed the
steam coming from my hood, and walked to get a new hose. I replaced
the hose, and added water to my radiator (as i unfortunately could not
get coolant). I then drove my car home. While driving, i experienced
the following problem; when i idle, or run at less than 1500rpm, my
temp gauge goes to about 5/6ths. When i run from 1500-2000rpm, my temp
guauge goes to 1/2. When i go above 2000rpm, my temp guage goes to
normal (roughly 1/3-3/7). I have noticed that only ONE fan is working.
Is it possible that with only one fan working, that this might cause
the problem? should i get this checked by a mechanic?? I know just
enough about auto maintenance to be dangerous. ANY help would be
appreciated. Thanks

=====================================

With a Honda, AIR in the cooling system will totally confuse the way the
fans work (don't work). When you lost coolant, you introduced air that
now needs to be displaced by the new coolant. Keep your rad full to the
top and the reservoir filled to MAX the next couple of days, since the
engine will take in coolant from the reservoir each time it cools off.
On a '94 you may not have to 'bleed' the air (others will know) but even
turning the heater on will introduce more (stored) air to the system. Be
sure to use premix Honda coolant, or at least don't use TAP water.
Distilled or reverse Osmosis is good. Tap water is Hondacide.

Trapped air will bleed out on its own just fine in all systems, provided
the system is otherwise operating correctly.

Correct.

De-ionized (de-i) is good, too.

VERY STRONG possibility of a blown head gasket.

Your symptoms indicate low coolant level, and thus poor coolant
circulation.

Depends which fan. You will have a rad fan and an A/C condenser fan. The
rad fan is towards the passenger side, and condenser fan is towards the
driver's side.

In the scenarios you list above, you do not indicate if the car is moving
when you are running the revs stated. If the car is NOT MOVING and you rev
it as indicated and the temp goes down, then the coolant is low. *Why* the
coolant is low is the question here, which is what brings up the
possibility of a failed head gasket.
