Does It Have to Drain Coolant From Radiator in order to Change Water Pump in a Car?

last answer was correct you only loose down to the level of the pump,. You say you suspect they have not changed it? In that case why was it being changed if it was not making a noise or leaking? All parts and work is guaranteed for 12 months anyway, so why worry.

1. how to know if you have a cracked block on 01 monte carlo?

coolant leak shall probably a hose or thermostat maybe even sensor. start checking all those including water pump. be sure the car has been defrost long time before checking out to prevent snow/frost leak from the outside.then trans or motor liquid shouldnt be leaking then check often your oil level. IF you found those leaking after all this from trans oil, motor oil it cracked so be sure to bring it to a garagist to confirm. low temp shouldnt do any damage like this depending on your driving style ... the coolant system is a long, long tube that pass through water pump, motor inside pass, thermostat, sensor, radiator ...

2. PWM water pump flow control - should I use capacitor for MOSFET? [closed]

I think you are talking about decoupling caps they are used to smoothen out the spikes and ups and downs in the power. But you are trying to control the flow level using pwm and if you add the Caps that would smoothen the pwm signal!

3. How long does it take a good shop to replace a water pump and a timing belt?

I didn't replace the water pump, just the snapped timing belt on my Volvo. Took about an hour with just minimal DIY tools.The head had seized the week before, it took about six hours to fit a replacement, camshaft snapped. I stupidly hadn't bought a new belt and decided to risk taking it home - it was 7 miles away. The old belt snapped 12 miles from home :-(Twin belts on a Citroen GS - aircooled flat four, no water pump but twin belts took me about three hours as TBH I didn't really know what I was doing, the sat and worried for half a day before I dared start it.It was fine :-)Photo only shows one belt, other one is the same on the hidden side of the engine. How long does it take a good shop to replace a water pump and a timing belt?

4. how much does it cost to replace a water pump for a 1995 dodge neon?

It would be cheaper to buy the tools and a book than to pay a shop. Don,t be scared and dig into it If the water pump goes than your timingbelt will snap and it is an interference engine so if that goes your in a world of crap.

5. What could cause a water pump to fail before the rest of the engine fails?

Well the water pump has seals inside of it that have to withstand high heat and caustic chemical mixes sometimes. It is a positive displacement type pump that has to work against a closed thermostat from time to time. The mixture of coolant that the water pump "sees" can vary greatly from a good mixture (at least 50/50) of the manufacturer's recommended coolant and pure distilled water to a very bad mixture of just regular rusted out hose water. So it also depends on proper maintenance. Usually the pulley, shaft, impeller, housing and even the bearings remain in good condition. The damage is usually with the internal seals that will leak.

6. Could the "whistling" noise i hear be related to a possible bad bearing in the water pump?

one tell tale sign of a bad water pump bearing can be a sound like a jet engine, but there are other possibilities too, I take a 4 foot length of garden hose put one end on top of what ever bearing you want to check and stick the other end too your ear.a slight hum is a good bearing, noisy bearings are easy to diagnose this way. Just be careful, no loose clothing or long hair near spinning fan and belts, engine has to be running to hear bearing noises. As to the dieseling noises, this is your engine running backwards. this is extremely hard on an engine. Leave the car in gear then turn it off. if its a stick, put it in a high gear let the clutch out until motor stalls. However dieseling is usually related to timing and poor quality fuel. Change to chevron super unleaded, it has techron which will help clean out a dirty fuel system, your vehicle may have a out of time problem, and or tune up issues can cause this. get this fixed, the fuel milege will be a bit better, and your engine will not self destruct. If the noise is in the water pump then replace it. Sometimes a jet engine sound can also be present in the torque converter in a transmission (automatic only)

GOT car problems? Graham Smith can help.Diesel's having a pink fitIn my 2007 Nissan Navara, the 2.5-litre turbo diesel stutters or hesitates and makes a pinking noise when it's cold but it's OK when it's warm. I have had it to two mechanics and they couldn't fix it. What do you think is wrongKevin RomanoCheck the injectors. Your problems are most likely there. --Just handle ItHow can I improve the handling of my 2010 Nissan MaximaAndrew, emailNissan specialist Jerry Newman is horrified at the thought of trying to improve the handling of the Maxima. He believes it handles well as it is and is better left alone. If you were to seek to improve the handling, you could fit uprated springs and struts but this would be expensive. Use quality components from the likes of Pedders. Perhaps you could check the web for components used in Japan but you must understand that whatever you do will have a detrimental effect on the car's ride and you might not improve the handling much anyway. --Annoying LeakMy Subaru Outback 2.5 EFI has developed a slow leak at the rear of the engine between the head and the block. I have had it pressure tested and that's the only place it's leaking from. It doesn't overheat and there are no bubbles in the radiator or water in the oil. I have had the water pump, radiator hoses and radiator checked and there are no leaks. I have had three independent reports by mechanics that say the same thing. To fix the problem, it's necessary to pull the motor out and I have been quoted $2800 to $4800 to do it. It has done only 176,000km and I am pretty dirty at having a head gasket go at this relatively early stage. Any suggestions for a fixAlan, emailI would try Bars Leaks or a similar product and hope it seals the coolant leak. To replace the gasket, which is the best fix, you would have to take the engine out as the mechanics suggest. --No Cruise ControlLast year my 2004 Renault Megane Turbo Sports started to play up with a miss in the engine when at a constant speed. It's not there on acceleration, only when cruising. I have had four mechanics check it. They changed the alternator and the exhaust sensor, the injectors were cleaned three times, new spark plugs were installed, it had the vacuum test and a camera up the exhaust pipe. One said it was a sticking exhaust valve but that would cost $4000 and it might not fix it! What can I doWarren, emailYour description of the problem suggests it is not an ignition problem. I would be investigating the fuel side of the equation, looking for things that might be making it lean at low throttle openings as you would be when cruising. Is there an air leak that is affecting the mixture strength, or something like that Having said that, it could be a sticking valve as the mechanic has diagnosed. --Towing The LineWhat would be the safest towing load for my 2002 Nissan X-Trail auto 2.5, and what would be the safest and best towing set-upGordon McCarthy, emailNissan rated the X-Trail to tow 2000kg with trailer brakes, so you should be able to safely tow up to that weight. --Engine FailureI have a 2009 Nissan Navara 2.5 diesel and I am concerned about the stories I have read of these motors failing anywhere from 60,000km to 120,000km. I have also read about the timing gear failing. Have you heard anything about this and if it's true what can I do to prevent itPhil Harrison, e-mail.There are reports of engines failing but these evidently were not serviced by the book. It is important to religiously service the Navara, and use the Nissan recommended oil. The failures we have heard about are mostly failures of the camshaft and cam timing gear, which have led to more serious damage.Originally published as
