Question about 2001 Honda Civic

2 Answers

Honda Civic 2001 lxi cooling system. The water pump does not function at the start of engine. I observed this thru the removal of upper hose of radiator to visually check if the pump discharges water while the engine is running. At first, no discharge has occured. But after approx 10 minutes, the pump discharged water and I noticed that the fans were also running. I assumed the pump system to be simultaneous with the fans (rad & a/c). When the fans stopped running, the pump also stopped discharging. To mean, the pump functions intermittently. I already replaced thermostat switch and removed thermostat from housing but to no avail. The water in the radiator got easily hot tending the cap to open its valve where water pass through going to reserve tank that usually overflows reducing the volume of water in the system. I observed that during drive, the temp gauge gradually rises up to max where I usually pull up and decide to cool off the engine, release pressure of radiator and refill with fresh water. Up now it is the situation. I already did the flushing of radiator by running the engine with injection of continuous supply of water from the faucet. The only thing I did not do was to replace the radiator cap which I suspect to be defective. Am I right on these underakings. As of now I have not solved the problem. Is there any more things I should do. I'm not familiar with this car model. Thanks in advance.

It sounds to me like there is an air lock in you're cooling system, and you should never use water in a cooling system unless it is an emergency. Start by draining all the water and replacing it with pre mixed antifreeze, you can use universal prestone anti freeze. Than when the system is topped up with the new anti freeze, approximately two 5 liter jugs run youre vehicle with the rad cap off, top up fluid in the rad, and wait for bubbles and for the fluid level to drop. Fill as needed, it may take awhile for the system to become full, when the bubbles stop wait approximately 5 minutes and if there are no more bubbles or fluid level decrease. you should be good to go.

    Sir, thanks for the solution you shared. It is so helpful.

    I just want to add that I forgot to mention "air lock." I already thought and did what you have mentioned. However, may be I did not completely finished it based on your shared know-how because as I wanted to add earlier, the water comes out of the radiator continuously (cap off) due to excessive pressure generated by the running engine that caused overheated coolant as a result of non-circulation of water to the system. So, topping up coolant did not happen. May be I have to further repeat the process based on your recommendation. Thanks again, Sir.

I have what you looking for ......
most of the cars made for Europe are equipped with a( thermostat ) but don`t confuse it with air conditioner thermostat or thing is working like valve that stops water circulating in cold starts so the water will only circulate around the engine block not through the radiator and of coarse it helps heat up your car`s engine faster but the problem comes when that valve got old (by the way most of those valves working as a wax capsule when the water heats to some amount the wax molten so it opens the way for water to circulate through the radiator ) what happens is simply the wax looses some of its function and molten in higher temp . so it block the water again until it heats up to molt the wax
my advice :
get off that part and just don`t replace it if you found it pricey for you your car still working but will needs more time to warm up
i hope i was useful for u sir .

How to tell if water pump is bad 3800 gm


The 3800's also had other problems. And also Issues for those that are unaware.

Be aware that there are bleeder screws to bleed air out of the system when filling the coolant. With out properly bleeding the system the coolant can Vaporlock in the system causing overheating.

Also if it has been over heated you need to check for a blown head gasket. Smell the antifreeze, if it smells burnt you should be concerned. Next with the engine cold and the system properly bled, leave the radiator cap off and start the engine, if it bubbles constantly or bursts out of the open radiator cap, seek diagnosis at your local repair shop as they have the equipment to do so properly.

I also suggest using an Infrared Thermometer to check temperatures with. if the engine is at 230f and the upper hose is at 200f, and the lower hose is still cool you likely have a clogged radiator. If the upper hose is cool as well then you have a bad water pump or t-stat. if the upper hose slowly warms, and you start to get bubbles then it's likely a water pump with the fins eroded off by electrolysis (gotta change that coolant at regular intervals)

Also make sure the radiator fans turn on.

2001 vw beetle service manual ? need to change water pump, how hard is it? dont look to bad.


Check this procedure to how to replace a water pump (DIY Complexity: Moderate / Time: 3.5 hours):

Parts:
1. Water Pump

Tools:
1. Screwdriver
2. Scraper
3. 3/8 in. Drive Ratchet
4. Cooling System Pressure Tester
5. Needle Nose Pliers
6. Socket Set
7. Radiator Hook Tool

Supplies:
1. Coolant
2. Silicone Sealant

Steps:
Step 1 With the engine off and cold, open the hood and locate the vehicle’s water pump.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.
o Tip: Before removing the radiator cap, squeeze the upper radiator hose to verify that the cooling system is not pressurized.

Step 2 Remove the radiator cap.

Step 3 Install cooling system pressure tester. Apply the pressure indicated on the radiator cap or in the owner’s manual.

Step 4 Inspect cooling system components for leaks.

Step 5 Place a drain pan under the radiator. Open drain valve or remove the lower radiator hose to drain cooling system.
o Tip: Depending on the vehicle, lifting the vehicle may be required to gain access to the lower radiator hose.

Step 6 Remove the drive belts or serpentine belt.

Step 7 Remove any hoses connected to water pump.

Step 8 Unbolt water pump from engine. Remove the water pump.

Step 9 Using a gasket scraper, clean the mating surface on the engine block.

Step 10 Install new water pump and new gasket. Tighten bolts to manufacturer’s specifications.
o Tip: You may want to use a light bead of silicone designed for water pumps.

Step 11 Re-install any hoses and belts that were removed.

Step 12 Re-install drain plug or lower radiator hose.
o Tip: Squeeze the radiator hose. If it feels soft you may want to replace the hose at this time. Always use new hose clamps.

Step 13 Refill radiator with a 50/50 mix of coolant and distilled water, then pressure test the cooling system and check for leaks.

Step 14 Fill overflow reservoir with same mixture.

Step 15 Leave the radiator cap off, start engine and let it idle. You should see the system“burping” bubbles of air. Refill the radiator to the top.
o Tip: Most air is expelled after a couple minutes of idling. Be cautious of potentially hot fluid overflowing.

Step 16 Install radiator cap.

Step 17 Road test vehicle, keep an eye on the engine temp gauge if vehicle runs hot, there still might be an air pocket in the cooling system. The cooling system should be topped off after vehicle has fully cooled down.

Good luck.

1994 Honda Civic LX\overheating within 2 mile drive


Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

Yes it looks like it. Provided you installed the thermostat in the correct direction, Here's the test, remove the radiator cap, start the car and wait for the engine to warm up, When you can see the temp begin to rise on the gauge the thermostat will open. While reving the engine look for turbulance in the coolant/antifreeze in the radiator opening.
If none is observed then replace the water pump.
