You need head gaskets. Compression from the cylinders is getting into the cooling system
1. Would an electric water pump be a good upgrade?
I looked into this before, and electric water pumps are not unusual for tow vehicles and high performance vehicles particularly in Austrailia where there are many long hot roads to travel. I would think there are technical benefits of an electric water pump over a mechanical one, specifically that a mechanical water pump varies with engine RPM, but for a tow vehicle, particularly towing up hills like the rocky mountains, you want to be able to have high water flow at low to moderate RPMs, so an electric pump not tied to engine RPM can provide enhanced cooling at highway RPMs. And installed in series with the mechanical water pump, it provides enhanced cooling. Aside from enhanced cooling protection while towing, I do not think it would save enough load on the engine to be really worthwhile, actually it will increase load on the alternator. At the other extreme, for a pure race vehicle, for short runs like drag racing or autocross, electric water pump can be still cooling the engine while it is shut off between runs, and can run total loss off the battery during the competitive run, and battery recharged between runs with an external battery charger. Under that combination of conditions, the water pump puts no load on the engine freeing more power to the wheels, but it is not a practical strategy on the road over distance and time.
2. Cost of replacing timing belt and water pump on 2000 Ford Focus?
have 500 handy and hope its 350 or 400
3. Is a water pump and thermostat attached to an engine? When you buy a new engine are they attached?
You only purchase the engine. Water pump and engine stat are seperate items. Again this depends if you purchase a short engine or a full engine
4. Do I need a water pump or is it something else wrong with my car?
Probably intake manifold gaskets leakingand you may have water in the oil
5. Need ON and OFF automatic water pump, which one can I buy?
Rather than trusting just anyone advice, I would just go to your local plumbing supply dealer in your area and ask. There are diffent pumps for different size plumbing. Also, alot of price ranges. If you buy one on-line and it doesnt suit your needs, you have the cost of returning it where as if you bought it local. ............well you get my drift. Good luck.
6. How can you tell if a water pump is bad or not working?
Well, you have asked this 5-6 times. Get it to a mechanic so they can check it out
7. Is it too risky to drive a car with the water pump broke?
If you fill the reservoir and leave the radiator cap loose (so pressure does not build), it should be OK to drive that long as long as you watch the temperature gauge. A tow truck fee would be a good insurance investment though! Check your insurance policy. Quite a few people have emergency road service on their policies and do not even realize it!
8. Is it my water pump or thermostat?
I would put my money on the waterpump just because if the thermostat was stuck wide open, ud atleastat least have coolant flowing and it would stay cool, unless its closed shut then your kinda screwed and have to take it out, personally if it was me iI would replace both by the sounds of it, 200k miles is a lot of miles
9. Can a water pump go out on a car from draining it and putting Anti-freeze?
It does not make any difference what type of anti freeze you put into a radiator if you have a leak at the water pump that only means that the water pump is bad and needs replaced.When a water pump reaches it use its time for replacement.There is a hole on the bottom side of the water pump that allows for pressure relief if it goes bad and if you have a leak coming out that hole it means the bearings and seal inside the water pump is bad. Look at it under the water pump and you will see a hole there if it is wet and a little rusty its time for replacement.Call up some parts store and get the best price on one but let them know what make,model,year,engine size you have and they will let you know what the price is for the pump.But also before you do that check to see if there is a hose clamp that also connects to the pump may not be the problem if so cut the hose back if you have enough hose to re- attach it back on to the pump. But also take the clamp and a screw driver and back off the screw on the pump hose end and bring it back off the pump so you can get the rest of the bad section of the hose off.Then put the the other part of the hose on the pump with the clamp.If you are not mechanically incline get someone else to do the job. But if that does not fix it replace the
