Q:how do I change out a 94 firebird water pump is it hard```?
1. Remove any radiator shroud, or any cowl obstructing the fan, radiator, and water pump. 2. using a pair of large pliers, take off the clamp on the lower radiator hose at the water pump and drain the coolant into a container. Make sure the motor is COLD, room temp, when you do this. 3. Remove the other hose. 4. Remove the cooling fan using an air hammer or a large adjustable wrench. This part is tricky, unless your fan is bolted on with 10 mm bolts, then you lucked out. 5. For step 4, leave the belt on, it will make it easier to remove the fan. 6. If you have a V-8 LT-1, then you have 4 13 mm bolts. Be careful not to damage your distributor which sits under the pump (nice design GM) 7. Using a razor blade, remove any gasket on the inlet and outlet on the block. 8. Apply a thin layer of gasket sealer on the gaskets for the new pump. 9. Install the pump, and its bolts. Use locktite if you have some on the bolts, medium strength. Tighten the bolts to about 90 in/lbs 10. install the pully, and fan. (again, tricky) 11. Install the belt. 12. put lower radiator hose back on (leave off upper) 13. pour 1/2 a bottle of Dex-cool coolant in the radiator 14. fill bottle up with 1/2 water, 1/2 coolant, and pour it into the reservoir. 15. If necessary, get new bottle of coolant, and pour it into the UPPER RADIATOR HOSE, this will help bleed air out of the system. 16. keep filling upper hose, and radiator until it stops bubbling down and basically overflows. 17. install upper hose. 18. make sure the radiator is full and system has no air pockets. Check to see if the upper radiator hose inlet has a bleeder valve. If it does, use a pair of pliers and open it, and watch coolant in radiator drop, then fillit up again. The V-6 has one, not sure about V-8. 19. put radiator cap on, and resevoir cap. 20. run motor, check for any leaks. 21. drive, if vehicle is overheating and there are no leaks, there is still air in the system. Wait till it cools down and bleed air again.
Q:Does the water pump effect the car AC?
You must know water pump is for cooling your motor ,by moving water around inside , AC has a pump or a compressor , Inside is a gas , under pressure the gas get cold when the cold lines are put in a space with a fan it makes cool air for you inside your car!!! All you may need is some more cooling gas for your AC pump
Q:Suppose the liquid temperature range for the water pump is -20 .. 90 °C.?
The pump will work well if it can increase head to 10 bar. Also, I think it will affect pump alignment, so you must determine hot alignment dimensions.
Q:37KW how many contactors does the pump need to start directly?
Direct start requires 250A contactor.Contactor is divided into AC contactor (voltage AC) and DC contactor (voltage DC). It is applied to power, power distribution and power consumption. Contactor broadly refers to the use of coils in industrial electricity that flow through the current to produce a magnetic field, so that the contacts are closed so as to control the load of the appliance.
Q:Marine cabin water pump?
most likely the pressure switch is stuck/corroded. this is a common problem with on demand type pumps.try tapping on the pressure switch to see if it will work.if the pump is installed properly,the motor should be at the top and the pump and switch will be at the bottom.i consider these pumps disposable. expect to replace it every couple of years.
Q:my expedition keeps over heating. i put in a new thermostat,water pump allready. help please?
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
Q:No Water in house/well/pump?
Well Pump Not Working
Q:well water pump questions...thanks?
The problem is either your pressure tank or your pressure switch. Since the switch is governed by the pressure in the tank, I would suspect the switch first - not the tank. You could check your pressure tank pressure using a tire gage, and make sure it is in the owner's manual operating range. The pressure switch tells the pump when to turn on and off - which is what fills the pressure tank. To check the switch, run the water until the switch closes and the pump turns on. Note the pressure at which it turns on. Now watch the pressure as it builds and note at what pressure it turns off. If you want less pressure, adjust the switch accordingly. We have ours set to come on at 42# and turn off at 65#. Our pressure tank air setting is 35 PSI.
Q:coolant leak after replacing water pump and hoses ?
could be anything, including loose lower radiator hose, backing plate for the waterpump(have gotten the things and the 2 bolts are loose and missing the gasket)get you a mirror and light, and start searching around it, did you do the thermostat?may have broken the housing, or pinched it.
Q:How do I know the timing belt/water pump needs to be replaced?
A water pump is mostly pretty obvious when it is going/gone it chirps it squeaks and your temperature will usually be higher than it usually was [not always]. As for a timing belt... they are relatively inexpensive, the labor isnt that bad since the car is VERY easy to work on, and it is difficult to tell when one is needed since the most it will make is a whining noise when its getting weaker, only sometimes though. This is hard to hear too. Best advice I have is to just get a couple appraisals/estimates, or have a friend who is mechanically savvy take a look to see if he/she can tell if the belt is worn to the point where it needs replacing. I had a timing belt done for $120 parts and labor on a 91 accord (same car)
