- Q:1978 Ranchero 500. Pumps leaking like crazy. I have a belt to remove, which i assume is the serpentine belt? Its tight as can be on the pulleys. I have no clue how to remove this and any other advice on this do-it-yourself project would be much appreciated. Thanks
- being a 78 it probably has a V belt instead of a serpentine belt. you loosen the adjustment bolt on the alternator and the long through bolt, push the alternator and the belt should come off. you will need to take the fan off, it should have 4 bolts to take out to remove the fan. then you take the hose off after you drain the radiator and take out the water pump bolts and pry off the pump. now before installing the new pump make sure the gasket surface is clean and dry. put some good sealer on both sides of the gasket. to keep the gasket from moving i use string like thread and tie the gasket on. put the pump in place, put the bolts back in and tighten them, put the hose back on, put the fan back on and tighten the bolts and refill the radiator. if you want good sealer use what i use. i use indian head shellac. once that stuff gets set up it won,t leak. auto zone sells it in a small brown bottle.
- Q:2005 pontiac grand prix 3.8 v6There is a scratching type of noise when i start the car. Looked under the hood and it seemed to be coming from the serpentine belt.Took the belt off and and checked the pulleys for any play and turned out the water pump pulley wobbles back and forth too much. Replaced the belt with a new one and want to replace the pulley. It does not seem to have a loose screw so i'm wondering if i can take the pulley itself off and replace it, or would i have to replace the pump too? Still makes the noise with new belt and you can see the pulley wobble a bit when the car is running.
- you have to replace the pump ! it,s not the pulley that,s wobbling, it,s the bearing in the water pump that,s bad and you can,t replace the bearing !
- Q:WATER PUMP, HOSES, 1998 TOWN COUNTRY
- this is just a rought est. but Parts: water pump $129, Hoses $45 Each, Coolant 2 gal $30, hose clamps $ 5. Labor: water pump 1.2 hours @$89 per labor hour = $106, Hoses .4 hours x 2 hoses = .8 @$89 = $71.20 plus a possible cooling system flush $69. So your looking at around $500 bucks.........that is probably a little high Good luck!
- Q:i have a 1994 honda accord lx. i was wondering what the water pump is for and if it goes bad can i still drive around without it thanks
- Honda Guy is right -- the water pump circulates the radiator fluid and ensures your engine operates at the correct temperature. If your water pump goes bad you should NOT drive your car. You can ruin your engine if it overheats. Get it replaced ASAP if it's bad.
- Q:How can I test to be sure my water pump is working before I go to the lake and burn up my motor. `72 65hp johnson. thank you.
- You can also go to a marina and buy earmuffs that hook to a garden hose and fit over your water intake. As stated above just look for a stream of water coming out the back of the engine.
- Q:Water pump part is stainless steel, which part is it?
- Of any part of the body that is in contact with water
- Q:I have a 1995 Jeep Grand Cherokee 6 cyl while driving home the other day my check engine light came on ,then I noticed my battery was loosing its' charge ,then I noticed my temperature gauge rising very fast.I stoped to see what the problem was.The vehicle had over heated and the serpentine belt was partially off Iet it cool down then I put water in it and drove it home which was about a quarter of a mile.I noticed no problems with the fan hitting the water pump pully until I put the belt back on .My water pump pulley appears to be off line how do I fix this?
- The water pump pulley is bolted to the water pump flange. The flange bolts are sheared off or have worked loose and the pulley/belt combination are no longer turning the water pump. If the flange has come loose from the water pump shaft, it will still be bolted to the water pump pulley. This may have also been caused by a locked up water pump. You can not fix a loose water pump flange or a locked up water pump. A new/rebuilt water pump will have to be installed. Happy Trails!
- Q:HelloI am building a small budget underground room. On top of a very waterproof and airtight (besides vents) building, and running a dehumidifer inside, I would like to install a pump underneatth the foundation to suck out water from the soil surronding the building but I'm not sure what kind of pump would be best?Also how would b e the best way to set this up?
- What you want is called a sump pump. Most have a system built into them that is triggered by rising water. The idea is to have a hole beneath that allows the inevitable water that will collect a place to go, then when a certain amount gets in the hole, the sump pump comes on and pumps it out to wherever you have the hose or pipes ran to. Being underground, good luck keeping the humidity level down. It won't be easy, and much depends on where your natural water table is, and what it is during rains. Someone in your area might know all that, I don't.
- Q:i need help on how to replace a water pump oil seal in a 2001 rm80...i looked everywhere...if you can get a video or detailed info that be great, thanks
- Drain coolant - #13 drain bolt Remove hose from water pump cover Remove water pump cover - #12 Drain oil Remove R side cover - #1 Remove circlip - #23 Remove water pump shaft - #19 Pull out water pump seal - #20 Note the direction the seal is installed Tap in new seal This entire procedure is explained in detail in your service manual.
- Q:i have an underground water tank, my jet pump went out again, got a new one, waiting for the guy to come install it. i got an old fashioned iron hand pump, for when the electric, or the pump goes out again, i can pump out water. got pipes, fittings, foot valve. i just dont know what kind of base to make ,to bolt pump to, over the pipe that will come out of the ground. any ideas?
- you can make a wooden floor cover using a treated good lumber of 1 X 6 for the floor and 2 X 6 lumber for the floor joist. assemble the 2X6 lumber for the floor joist. depending on the top area of your water tank. arrange the floor joist at 0.60 meter spacing and 1.2 meter braces. after that, use 1X6 lumber as flooring with at least 2 cm spacing between lumber. as on the base of your pump, you can reinforce it by adding 2X6 braces. use a lug bolt depending on the size of the slot at the base of your pump then bolt it on top of the 1X6 flooring. its better if we can draw it here to make it easier to understand and explain i dont know if this can help much because we havent seen the actual situation of your tank and your pump.
