Question about 1998 Honda Civic

1 Answer

Have a 2001 Honda Civic LX. Just had a radiator flush at Pep Boys. My water level is high. No coolant leak. My engine is NOT steaming. Every now and then [please note this does not happen ALL the time] [[after]] I have driven for about an hour or so, the temperature gauge will all of a sudden shoot up all the way to the red mark. I'll turn off the car for about 5 minutes, check under the hood to make sure there is no water leaking or hot steam, as well as check the radiator water level. Everything is normal. I then turn on the key to ACCessory [[without starting the car]] and the temperature gauge will shoot all the way up to the Red mark. I also turn ON the Fan and Air Conditioner and the temperature gauge shoot all the way up to the red mark. I then check under the hood to see if the engine fan comes ON, which is the case. When I turn OFF the Fan and Air Conditioner, the temperature gauge goes back ALL THE WAY down and the ENGINE FANS (right one and left one) also go off. I then turn on the engine -- [[without]] turning on the Fan and Air Conditioner -- to see if the ENGINE FAN will come on. The ENGINE FANS (left and right) do NOT come on. I then turn ON the Fan and Air Conditioner while the engine is running and both ENGINE FANS (left and right) will come ON. I 'll then turn OFF the car and wait for about 20 minutes or so and put my car key back in the ignition WITHOUT starting the car. The temperature gauge will go back to its Normal (mid range) position. I'll turn on the fan and a/c and the temperature gauge stays normal. I'll then turn on the engine and the fan and a/c and the temperature gauge stays normal. What could be causing this ON AGAIN, OFF AGAIN problem? Could the radiator cap be bad? Could it be a bad fuse? Could it be a bad sensor? If it is a bad sensor, HOW much would it cost at the dealership or any Honda repair shop to replace it? With respect to any possible solution, what is a fair repair cost estimate?

There are only a few things that will cause this problem, one is a slight leak at the head gasket of the engine, combustion gases leak into the cooling system and create a gas bubble around the engine thermostat (this controls the flow of coolant in the engine), this stops heat from transferring to the thermostat and it fails to open, hence the overheat, the 2nd is the possibility that the thermostat is defective, they do stick, before doing anything else have the thermostat replaced, they are relatively cheap to have replaced and this may be the problem, the other possibility of the head gasket involves major engine repair. Was your cooling system rusted? if so just a flush of the radiator won't do, u must have it removed and professionally cleaned by a radiator repair shop.

SOURCE: leaking proportioning valve, and master cylinder

a salvage yard part would be fine,and would be a fraction of the estimate given you by Pep Boys. that estimate is really high,btw. kia is a good vehicle when properly maintained. if finances are an issue,i recommend using sme Lucas products that are additives,they wont fix your problem peranetly but can definately hold you over a month or two.

SOURCE: no spark spontaneous failure pep boys cannot

Hello! I'll need a little clarification...What size engine is installed in the vehicle? How did you determine that the engine looses spark? When you say spontaneously or at times; Is there a relationship to a cold or hot engine? Guru............saailer

DO NOT GO TO A DEALER

You have a code for the ABS System

The most common cause, is a bad front
wheel speed sensor

PEP Boys should have found and fixed it in
30 minutes

No Professional I know of,sends people to
a dealer.

I have the same car.

Try a local repair shop that has a good rep for
diagnostic work

Why do i overheat?


Low coolant level, bad thermostat, bad water pump, dirty radiator on outside, radiator tubes clogged internally, etc.

Till u fix turn on heater full blast & open the windows. It will help keep the engine temps down so you can use it while getting repairs.

first check the coolant level and make sure it is topped off. Check the water pump drive belt to see if it is loose. check the water pump by pinching the top radiator hose closed with your rag covered hand with the warm engine idling. When you release it, you should feel a surge of coolant in the hose if the water pump is working properly. The thermostat may be stuck open--changing it may help. There could also be a restriction of some kind in the radiator or heater core. Flushing the system may help.

Check your Tail Pipe to see if there is any water coming out of it. Also, Pull your Oil Dip-Stick to see
if there is any moisture on it, or if the Oil has a milky appearance.

What could make my 03 civic ex overheat and cool down then overheat again while losing heat inside??? Already replaced radiator, water pump, thermostat.... motor


your heater has apparently restricted the coolant flow....hopefully a good system back flushing will cure the problem....use a flush obtained from a parts house....I would buy the hose kit for flushing as well...good luck to you

My honda will not heat when it is sitting still give it a little gas and it wiil heat what do i need to do


Check your coolant level, more then likely low, check coolant level with engine off and cold. not enough coolant will not circula through out the cooling system at idle, till you give it gas then water pump turns faster and pushes water through out system,

The coolant that you are adding fills up to the top of radiator, then slowly drains down through engine block and water pump, You will have to fill radiator completely about 2 times for it to stay full for good.
