Q:I had a re-manufactured water pump installed and after 14 months I started smelling my radiator occasionally. Never suspected the pump since my original pump lasted 60,000 miles and was still fine when they replaced it feigning quot;it is customary to replace water pump with timing beltwhen in actuality my Hyundai Elantra just needs the pump checked every 60,000 miles. The re-manufactured water pump was diagnosed leaking for sure after 20 months. Anyway I believe the leaking pump which didn't get discovered for at least 4 to 6 months caused the early demise of my radiator. Does that make sense?Thanks,Mitzi

i strongly disagree. a leaky pump, loosing fluid, replaced by air via a recovery system, will create excess water jacket pressures. ergo, the radiator. even if it has air trapped in it. that excessive pressure, if the rad is marginal/old, can cause rad leaks. any seasoned mechanic out there has experienced a vehicle that had air in it, and be so hot as to charge the system. on some, you can actually here them go bang as water/coolant, flows into a part of the systems that has just air. that sends pressure shock waves through out the system. i've experience some so hot, they won't shut off. dieseling per say. ---------- EDIT, Michael sir. i'm an ex fighter jet hydraulic/pneumatic tech USAF. 40 yr auto mechanic. 5 yrs on Harley's (iron blocks). been dealing with the use of compressed fluids and gas for some time now. ex boeing employee on the 747 as well. i just don't ahve all that in my profile. mostly, i just let facts speak for themselves. weather or not an OP see's that is up to them. --------- pressure can built up faster than it can be bleed off in *some* cases. especially if it's a slow leak. those were generic statements. meaning, they are a possibility. not out of the realm of possibility, and would be far from the first time it ever happened, that a bad pump can cause other parts of the coolant system to malfunction. i've seen marginal rads, hoses, and even heater cores go as a result of over pressureazation of the water jacket. but i meant no disrespect here. i will delete my seasoned mechanic remark. simply stating i have seen/experienced, in the shop, over the years, many instances like what i stated. it's not impossible!!! i'll delete all this crap too if you delete your remark. how bout it? friends?

Q:My 2005 Lexus IS300 is close to 90K miles and I believe the timing belt/water pump should be replaced. I have priced this with several dealers and mechanics and at this time I can't afford close to $1000 to have this done. However, I see there are kits that can be purchased for about $400.Can a DIY'er with above average mechanical experience replace the belt nd pump relatively easily?

Alot depends on having the proper tools and knowledge . If you have the right tools you could try it but i have known a few people that tried doing there own t-belt and ruined there motor . I am not trying to scare you just don't want you to cause any more expence for yourself. The water pump is easy once you get the belt off . If you do try it heres wishing you good luck

Q:We had to have our well pump replaced yesterday, how long before the well settles down, and the water tastes like it used to?The company who replaced the pump told us when changing a pump it disturbs the well, and it would take time for everything to settle back into place. Thank you in advance for any and all suggestions.

I had my pump changed and the water remained the same. It looks like you didn't really need a new pump, but a new screen on the well itself. Ask a well company what they think. I thought it was my pump, too, until I found out they had to change the points in my well to the tune of $1,000. Changing the pump should have never changed the well....sounds like you hired a plumber.... Good Luck!

Q:My water pump is starting to leak. The shops are quoting $250- $300 to replace but I can buy a water pump at the auto parts store and install myself for less than $100 but I don't know what all is involved with this repair or if I should try (my only experience with car repair up to now is recently replacing the alternator). If anyone has done this please let me know what you think. thanks

It's a rear wheel drive car with the water pump mounted on the front of the engine toward the radiator. So if you go to the library any read the chiltons or motors manual procedures on how to replace the water pump, you probably have to remove the radiator fan blade assembly to get at the water pump. Some fan belts will also have to be removed. You can end up doing the job twice if the new water pump gasket doesn't seal properly due to antifreeze leaking out of the engine block while your installing the new gasket and sealer. Park the car with the engine facing up a hill to prevent that. I'd have it done at a shop. It's worth paying a shop unless you really want to get into major repairs.

Q:I want to replace a water pump for my friend. I can't find any books on this car. I'm not sure how to replace this pump. Looking at new water pumps there lookes like 10 bolts, but on my chevy truck there was only 4. I don't know if all holes take a bolt or not, or if I need to take something out before I take the water pump out.Anyone ever changed a water pump on this car? or know what book or website I can look at which will give me an idea.

autozones web site has some good instructions on most popular cars

Q:I just replaced my water pump.fixed.. A week later I've been noticing he might of over filled it because.were the coolant goes.steam comes.out.the little.while plus water.. And.before.I.started my.car I noticed.it was all empty now and my.engine sounds like a mini diesel when it runs.. What's the deal? And I.already filled it up with coolant again

if it is low you still have a problem

Q:Difference between primary hot water pump and two hot water pump

Primary pump variable flow VPF (variable primary)Flow) system is the new layout of central air-conditioning system, compared with the one or two pump system has more advantages in initial investment and operation cost. At present, some with a pump with variable flow system engineering in the operation of many problems,

Q:Had a water pump start leaking, when I replaced it with a new one, it leaked even worse (around the gasket and O rings this time). The process I took...I unbolted everything and removed the water pumpI scrapped everything off with a wire brushI coated both sides of the gasket with red gasket siliconI mounted the new one and bolted it down tightening in a cross pattern(kinda difficult to get everything lined up)It leaked real bad the first time so I loosened the bolts and played with the top rubber seal to make it seat better.It leaked a little less the second time... but still WAY too much.I completely removed it the third time and (totally distroying the gasket) gooped it up with gasket sealer again, along with the O rings and tried again... leaked worse.Considering options... go with a white or black high heat siliconPossibly just using the sealer with NO gasketGooping the HECK out of it with JB-weld and pray!Suggestions?Know what I did wrong here?

Two questions 1) Did you buy a new gasket? 2) Did you let the sealant set long enough? If you answered yes to both of these than the only thing left is to make sure you have the right type of sealant. Is it the waterproof stuff for waterpumps? You mentioned the stuff was red, it's been a couple of years since I changed a waterpump but I believe it was the BLUE stuff that I needed. But I could be wrong. Take it apart. Make sure it's clean (you can use a wire brush but I find a paint scraper works better) and apply the new gasket to the new water pump then but the whole thing back on the engine. Star pattern tightening the bolts. Test it without putting the clutch fan (I think this still has one) back on just to see if it's leaking. Hope that helps.

Q:I have a 1.5 horse Power Hit and Miss engine? Is it possible to buy a water pump I could run off of the hit and miss engine that would pump water from a river over a big hill and little ways and into a water tank or is this just a waste of time. How much water could I pump at a time? A trickle or a gush of water? When I say hill I don't mean like a little hill in your yard I mean a hill you have to hike up? If you don't know are there any resources I could access? Where could I buy such a pump if there is one?

A horse and a half won't do much. You would be better off with a hydraulic ram type pump if you can get about a 10 or 15 foot fall before the ram. It will pump about 4 or 5 times the height of the fall, but in small quantities. It will run 24/7 without gasoline, so it will fill a tank over a long period of time. The railroads used them during the steam era when they had huge water towers out on the plains.

Q:What is the reason that the water supply of pump is getting smaller?

What kind of pump is it, home pump or factory pump? Single stage impeller or multistage impeller? Vertical or horizontal? Is it single suction or double suction? Different structure of the day pump has different causes of failure. But in general, there are several aspects: 1., the water inlet is small, the inlet pipe is blocked; 2., the blade is worn or broken; 3., the motor speed drops; 4., sealing serious leakage; 5., cavitation phenomenon.
