- Q: I replaced the water pump on my 350 chevy small block and the thing is leaking out of the lower bolt hole on the passenger side. I was told to remove the bolt and coat it with permatex hi tack gasket sealer and reinstall it. Any how I'm wondering why there would be a leak there in the first place, any ideas?
- my first response is, you used a wrong gasket or you mucked up the gasket when you installed it. Then i think of maybe the water pump casting cracked when you tightened the bolt. ( but not likely) . I guess you could try the sealer thing. but you could test it to see if it leaking from under the bolt head. The way you could do that is put a soft washer , like copper washer under the bolt head and put the bolt back in. the soft copper washer will make a water tight seal. if it were me , i would remove the pump and find out what the hay is wrong . i have replaced at least 6 water pumps on my own chevys, and have never had that problem.
- Q: Ac was working fine before the mechanic replaced the water pump. Now the AC only blows hot air. Is this related?
- Ac Water Pump Not Working
- Q: I have replaced the presure switch on my water pump but it switches on and off when it is building up presure instead on staying on until it gets to right presure.Any ideas of what is causing this?
- your tank is waterlogged turn the power off to the pump and drain the tank of water completely and turn the pump back on this should do the trick Ive had it happen to me and it worked
- Q: i installed a new pump don't know how to increase water pressure and to what what pressure it should be set
- This is very simple i would sugest the pressure to be set betwene 60 to 70 NO MORE THAN 70. 1. turn off power to pump (ether the circut breaker or a switch near the pressure switch) you dont want to weld the wrench to the switch. 2. remove the cover to the pressure switch its self (usly one #2 phillips screw) 3. now you will see 4 wires under some sloted screws nearest to the front of the switch, behint that is 1 or 2 bolts with a spring and a nut. 4. if you see 2 bolts you will want to turn the nut on the larger one to the right. you will want to tighten it about 1 to 2 full turns. (the same goes if there is only one bolt also) 5. now open the valve that is on the tank untill you here the switch click. then close the valve. 6. turn the power back on tio the pump and watch the pressure gauge on the tank. i DO NOT RECOMEND MORE THAN 70PSI. 7. if it goes over the pressure you want repete steps above exept loosen the nut in about 1/4 to 1/2 turns untill you reach the desired pressure 8. if it does not reach your desired pressure then you do the same thing exept tighten the nut in 1/4 to 1/2 turns untill you attain your desired pressure. 9. when the pressure is reached, replace cover so you dont risk rusting the contacts. if you need more help feel free to email me. and i will assist you in any way that i can.
- Q: Recently my car overheated on my way to work, and so I decided to give it some much needed TLC.I have replaced all in the last week:Spark PlugsDistributor Cap + RotorTiming BeltRelated to the cooling system:Water PumpThermostatAnd the heater still blows hot air so I believe the heater core is fine. Unfortunately even after a couple of radiator flushes the car continues to overheat. I'm considering replacing the radiator because I think it might have too much debris inside to flow properly.I used ZEREX Radiator Super Cleaner but was only able to acheive an hour and a half of driving before my car would not be able to drive anymore. (Supposed to be 3 hours, car temperature began to escalate far beyond what I'm confortable with) I also used ZEREX Radiator Super Flush to no avail.Any suggestions?Car info:Toyota Camry DX 19913S-FE Engine 2.0L I4 1998cc244,500 miles
- If your fan is operating.. check to see if the water is circulating. Leave the cap off the radiator and bring up to temp..If it is not, you may have a vapor lock in the system, and will have to bleed the air out.
- Q: I have a 1997 ford ranger, during last week i noticed that the temperature started to go up, i noticed that the coolant recovery tank was empty so i added coolant and it fixed the problem, but a day later i noticed that the tank was empty again since it started to overheat again. This time i let the engine cool off and checked the radiator water levels and noticed it was dry with no water, so i added water and noticed that i was leaking from what it seems the water pump (im guessing its the water pump because is behind the engine fan, behind the belts, its hard to see), Does anyone have a possible explanation or suggestion of what i should do? Thank you i would really appreciate it.
- You will need a new water pump if it is comming from where the fan bolts on. If its around the outside of it, it could just be a gasket but I doubt thats the case.
- Q: So I have a 2.4L chrysler cirrus. The water pump appears to be not working(pumping the fluid through) and the car over heats. They location is on the side since its a front wheel drive car. I have both a Chilton and Haynes manual and they both say i need to loosen the front engine mount and lower it. Thats about it really..Now i was wonder couldnt that mess up something. I dont plan on doing this myself but i would like to know how. Is it possible for the engine to fall out? Might sound stupid but im not sure how all that will work so i would like to know. Thanks -Joe
- There is some room to move an engine/trans slightly to get to parts or perform maint. The actual movement is probably not that drastic, but most have the proper equipment to handle this. I wouldn't worry about it as long as it is being done by someone with experience.
- Q: My well is 58 meters deep, the water level is 20 meters, the water level has not been measured. What's the maximum water pump I should choose?
- Deep well pumps can be used. According to your parameters. 0. 75 or 1. The 1KW deep well pump is in line with your requirements. Elephant 0. 75KW head can reach 70 meters. The water output in an hour is about 3 tons.. I wonder how much you get out of the water every hour. If the amount of water is small, you can buy a larger power point. General domestic deep well pump 0. 75 or 1. The price of 1KW is between 500-700. In the case of ordinary brands. The price of imported goods is between 600-900. The products at this price are generally of good quality.. Of course they don't sell your shoddy premise.
- Q: It hasnt rain in quite a while, but I havent had any problems with the water or pressure, but it seems like the pump is always quot;onquot;. I purchased this house almost a year ago, never had a well, so I now very little about it. I moved in December, rain season here in NC, and remember the pump going on and off, now its constantly running, Is it normal for the pump to be running that much? any websites to read up on how a water well works?thanks
- In the first place the pump should be able to run constantly without a problem, they're made to do this. In the second place go check your tank, see what the pressure is. You must have a water logged tank First: unplug the electric to the pump and then drain the tank completely. Once this is done make sure the tank is drained, plug it back in, wait and see where it stops at, the pressure. It should be about 55 to 65 pounds. When it stops have someone flush the toilet, it should slowly go down, it may settle without turning on, some do. If so, flush it again. Watch it again. When it starts up, keep your eye on it, it should go back to where it was to start with. If it doesn't then the volume control on the end of the tank, with the small tubing coming from it to the switch is out and should be replaced. You have to turn it all off again, drain the tank and replace the volume control. If the switch doesn't stop but, it comes to the end and doesn't open to stop and keeps running, then your switch control is shot and you'll have to replace that. If you have a bladder tank, it should say on the side, then you should empty the tank, as in the upper questions and then using an air pump put in about 38 pounds or whatever the tank says to put in the bladder, then fill it with water again. See if that's the problem.
- Q: my 98 expedition keeps over heating, i replaced the water pump, thermostat,coolant. it will be fine one minute then it overheats. weather im on the road or sitting at a light. i also replaced the fan clutch. thanks!
- If you have the 5.4L motor it will have a plastic intake manifold. Look at the front. There is an aluminum crossover pipe attached to the front on the top. Those are famous for leaking aroung where the intake meets the head and where the aluminum and plastic meet. You may need a flashlight and a small inspection mirror to check all the way around. Also if the valley or apace between the heads has coolant sitting in it that's a good bet you have a leaking crossover or a head temp sensor leaking. The head temp sensors are located at the back of the heads. The other common spot for coolant to leak is the heater hoses be sure to check at all the fittings and make sure they haven't come apart up by the firewall. One last thing to check is the belt around the water pump pulley. It is easy to put it on so the water pump spins the wrong way. Common mistake. Lastly if the manifold IS leaking do NOT attempt to do this if you do not have a top notch torque wrench!!! You can very easily strip the bolts or holes that are in the heads. If you are not sure take it to a good technician. Dorman makes a good replacement manifold for about 200-300 bucks. The gaskets are made onto it. I have had no issues with that one leaking. Also do not try to relpace just the crossover... I know that it has bolts and they sell gaskets but it will leak. If the manifold needs to come off it is also a great time to change the plugs. They will be super easy at that point, be sure to use new Injector o-rings too. Hope that helps. Jim
