Q:I just came from my dealership and they tested my car with a pressure test. They didnt notice any coolant leaks. Last week my car I noticed that the coolant level has decreased. I had to replenish it in an emergency effort. I am curious to check the water pump. I am going to ask my mechanic tomorrow if he could check it and how much does something like that cost to check? I DO NOT want any coolant leakage getting into my engine because that could present a problem. How can it possibily get to the engine???

If you had a water pump leak you'd know it! There would be coolant draining out of water pump seal the minute you filled the cooling system. A water pump leak doesn't get coolant into the motor. It will get the timing belt wet with antifreeze and cause the belt to jump time and possibly bend your valves. The only way you'll get coolant in the motor oil is if there is a head gasket leak. To check for that you need to have a block test done.

Q:i need to change my water pump on my vw 1990 gti. the more details and/or pictures the better or links i can go to to show me

Buy a repair manual. Or better yet buy a lifetime replacment one at Autozone and they will print out a step by step (with pictures torque specs) instructions for you. :)

Q:I have a 1997 mercedes 320e and it is leaking very bad. I need a temporary fix for the water pump, so that I can take it to the repair shop that is 10 min. away.

Don't try and don't listen to these idiots telling you to leave the cap off or give it a go. The engine will get hot in much less than 10 minutes and those heads are very lightweight aluminum that don't do well when overheated. Not having pressure in the cooling system is almost as bad as not having water with that engine. The easiest way is to have someone replace the pump on the spot. Otherwise, shell out the $50 for a tow unless you want to risk trashing the engine.

Q:Hello online mechanics! You guys have saved me a lot of money on my car, so now I have a new question! I have a 97 Ford Contour and lately since it's been cool in NJ, I've been hearing a tapping coming from the timing belt cover, but when the car warms up, there's no sound. I took the car to my mechanic and he says that I need to have the timing belt replaced, the pulleys adjusted, and the water pump changed. The price for doing the timing belt was $400 (including adjusting the pulleys) and $700 for the timing and the water pump. My question is ; do I need to do the water pump? He says that if you do the timing belt, that you should do the water pump too, but should I if there's nothing wrong with it ( as far as I know) and I'm not looking for the added expense? I thought if it ain't broke don't fix it still applies to things, or am I mistaken? Thanks guys gals! In these tough economic times, I'm not looking to spend any more than is necessary!

ask some of your friends if they have a mechanic that they trust . Take the car to them and see if you get the same answer ?

Q:my water is frozen from pump to faucets,do i thaw from pump to faucet ,or faucet to pump?

open faucet nearest pump, use hair dryer on line from faucet to pump. Of course you need better insulation, but you can leave a faucet drip to help keep the line from freezing up until then.

Q:I live in a residential/country area, and I have a well pump down cellar. I notice that, even if I am not using any water, nothing is running (toilet, etc) it tends to cycle on and off every hour or so. The pressure is always good, so that's not an issue. I am just wondering....is it normal for it to do this?

How long does it pump when it turns on? This sounds like short cycling; you might have a leak somewhere in the system.

Q:antifreeze leaking from the water pump. antifreeze wont stay in car, car overheating. 96 chevy cavalier. 2.4

Is it leaking from the waterpump itself or the gasket.It may be overheating because its out of water rather than a faulty water pump if the gasket is bad.

Q:55KW motor driven lift 70M, the displacement of 180 cubic meters per hour of water pump, the configuration should be no problem, but after the start of the current to 170A (rated 100A), off a small valve to the current export half to reach the rated current. Why current will close a small valve instead of small? Will close a small valve will not affect traffic flow can be? To the 180 party?

170A has shown that the motor is overloaded; the head 70M; the displacement of 180 cubic meters; the approximate power is 42Kw (efficiency is higher). At this point, the current of the corresponding motor should be approximately 86A;The power of water pump is related to the quantity of water transported. The water pump is a passive energy conversion device, and it has no regulating ability. It depends entirely on the intersection of its pipeline characteristics and its own characteristics,No, your situation is the pump and pipeline characteristic, the pump head is higher than the resistance of pipeline, so that the water flow movement (increase too large). Pump power becomes largerShut down the water pump, the valve will certainly reduce the amount of water, as for whether to reach 180, you can see the pressure gauge to show the pump lift to determine the pressure of less than 70 meters, the flow of more than 180

Q:mechanic says the bearings are going on the pump, and they might as well replace the thermostat while they are there.my question is he right?do they have to remove the engine to replace either the pump or the thermostat?seems like a lot of $ for a what should be a simple job ($450).thanks for your help!

The waterpump is very hard to get at to replace it. They do no thave to remove the engine, but they do have to remove a lot of the components to get to the waterpump. And it is a good idea to replace the thermostat while they have all the components removed. That way you can be sure that the thermostat will not be a problem later on. Especially now during winter. I think that is a fair price, unless you can get somebody else to do it other than a pro. It is worth saving your engine. If it gets hot, and you run it, your heads may become warped, your waterpump will give out and will cause much more damage. you will have to replace the pistons , rings, or probably the entire motor. good luck my friend.

Q:I am putting in a new water pump this morning on my 2006 chevy trail blazer and i rented the clutch fan removal tools but im new at this and i cant afford anyone else to do it. any advice for a rookie it looks so simple am i wrong

It is very easy and straightforward. The hardest part is the fan clutch unless you have the proper tools. You have that part covered. DO NOT USE ANY SILICONE SEALER!!!!! Be sure all traces of old gasket are removed and install the new gasket dry. Use an anaerobic sealer on the wet bolts. Those are the ones that are through drilled into the water passages. Clean off the threads then use a light coat of sealer. I use either Permatex (brown stuff in the tube) or pipe joint dope. Now is also a great time to flush the system, replace thermostat, and drive belt(s).
