Q:2000 Ford Focus - water pump?
2000 Ford Focus Water Pump
Q:Decoration Water Pump Supplies?
Home Depot, Lowes, Michael's craft stores, waterfall and water feature stores, Target, WalMart and sometimes Big Lots. I've also found supplies to build decorative water pumps at my local nurseries, Green Thumb and Armstrong.
Q:My water pump is leaking?
go to a mechanic,,I don't trust you to make a proper diagnosis
Q:What all do I need to replace the timing belt and water pump?
HOW MANY MILES! This is a TOUGH CALL because a CONTINENTAL TIMING KIT for a HONDA is about $200 with NEW WATER PUMP PULLEYS and and BELT! A HIGH MILEAGE HONDA from taht year may bend a few VALVES if the belt breaks BEFROE you repalce it! Thsi wil requrie a NEW HEAD GASKET and a few new VALVES! AT this time NEW VALVE SEALS can be installed! An independent shop can do ALL THIS for about $1400-1500! he BELT KI is like waht I said here! OTHERWISE use ONLY GENUINE HONDA PARTS int here! teh CONINENAL kits are GREAT and made to HONDA PRECISION as well! PULLEYS and ENSIONERS are involved in thsi process, and only GENUINE HONDA COOLAN should be used ONLY! NO PRESTONE! Stay away from VALVOLINE OIL as well, it is made by WAX REDUCTION METHOD!
Q:How can I pump the motor insulation?
The cable head in the distribution box should be relieved. What's more, the motor insulation is not the pump insulation. Usually, just shake it in the middle of the water and the ground.
Q:Is The water pump working?
First let me say the GOOD LORD was watching over you. You NEVER NEVER NEVER open a radiator cap when it is hot. Had a friend do that and he now has scars on his chest where the water sculled him. Yes it is working. What you need to do is change the thermostat. But please wait until the engine is cool to the touch.
Q:What's the difference between a double suction pump and a single suction pump?
The 3 floor of a friend, the next time you quote us the trouble to answer, please indicate the source, at least to keep integrity! Now on the market a variety of micro pump, micro pump, micro pump, high pressure micro water pump, liquid sampling pump, small pump, self suction pump, DC pump, diaphragm pump, whether has the function of self suction, mainly refer to the following two points: 1. means: self suction pump suction pipe is in the air, using form a negative pressure pump at work (vacuum), under the influence of the atmospheric pressure will be lower than the water pumping port, then discharged from the pump discharge end. Before this process, there is no need to add "diversion water". The pump with this capability is called a self suction pump". 2., some centrifugal or rotary vane pump, before absorbing water, you must add "water diversion" in the pump cavity to form a closed environment, and then pump operation to form negative pressure, to achieve the purpose of water absorption. For example, a manual pump used in rural areas. No self-priming capacity of the pump, each time before adding water to add "water" is very troublesome. 3., suction level, with the pump power, flow, structure and so on, but the general micro pump self-priming process is not easy to do higher
Q:Whats wrong here? 98 Cavalier z24 2.4L antifreeze/water pump?
If you are loosing water due to a leak coming from your water pump the radiator can not hold pressure making the water over heat that is where the steam is coming from and as far as how long it will take you to replace the water pump time will tell if this is your first time it may take you 8 hours but like they say it is better to have tried than to have not tried at all.
Q:2001 Intrepid 2.7, water pump & timing chain?
I also own a 2001 Intrepid and recently had a water pump go bad which also broke my timing chain. The pieces of aluminum you found are probably valves or valve springs from the head. Mine broke every vavle and spring on one head when my engine jumped time and a few more on the other head that is probably what your seeing. Also you don't want to check for compression by turning the crank manually. It is an expensive job to fix but the cars are great but I wouldn't spend too much on them because they only go for about $3000-3700 in great condition nowadays. Good Luck
Q:Is my water pump going bad?
LOOK on internet! WHAT SIZE IS ENGEIN HERE! FOur, five, six, eight yidner from WHAT COMPANY! NOBODY can answer thsi question for you without MORE DETAILS! THANX!
