Q:when replacing the Water pump on an Isuzu rodeo while getting a new gasket does it require gasket sealant for this type of vehicle?

it depends mainly on the gaskets you are using whether or not they are paper type gaskets or rubber type gaskets or cork type some cars have only sealant and no gaskets most rubber gaskets don't need sealant some install it anyway for extra protection but to much sealant it could clog your cooling system if they are paper type gaskets a little sealant is added protection some mechanics put sealant on the gasket simply to hold it in place during the install some gaskets require sealant and a specific one at that there are many different types of sealant keep in mind if your gasket manufacture requires sealants to install its would be listed on the box it arrives in for the pre installation guides make sure you get the one they say also all sealant that dry some are wet sealants and never dry, keep in mine that if the sealant requires dry time after install you follow those guide lines otherwise it will leak keep in mind also that the water pump housing bolts have a specific install and tightening and torque down for that type of gaskets like 15 foot pounds on the bolts for cork type gaskets if you crank the bolts down to tight its going to split the gaskets and your back to square one replacing it again

Q:First the shop put in a heater core, but it was still leaking and overheating. Next they put in a water pump. Went to get it and now it wines really loud and the engine use to purr like a kitten, couldn't even tell it was running, now the engine shakes the whole car and it died one the way home but started again. The shop said the cam positioning needs reset again and on the way back to the shop it died again. So from leaking anti-freeze to now it vibrates, dies and wines really loud ! Any ideas what they did wrong ?

Yea, this engine has the water pump that is driven off of the timing Chain, before removing the pump you have to install a holding tool to keep the timing gears synchronized, If the pump is removed first without installing the tool, the camshaft timing will be out of sync. and that's what probably happened. NOTE: This sounds like an unqualified shop to work on vehicles, if they can't trace a coolant leak! The first thing that should have been done is a CO2 test on the cooling system to see if the vehicle has any hidden head gasket issues. (Good luck)

Q:99 Cherokee I6. There is low pitched noise coming from the area of the water pump and alternator. Like a grinding grumbling. The water pump pulley is not loose and will not rock back and forth. Nothing is leaking. Tomorrow is forecast as icey and I have a choice of sending my wife 30 miles each way to work in the Cherokee or a 2005 Mustang, which is absolutely terrible in the snow or ice. I can get the car into the shop on Thursday for diagnosis and repair. Since the pulley is not loose I am thinking it will be OK for another day even if it is the water pump bearings. Thoughts?

Have you got a long screwdriver or metal rod that you can set against each place you need to check the sound. If so with auto running place one end on suspected bad unite and the other end up against your ear hole. Bad sounds will be exploited with this manor of testing. Be careful OK!

Q:My 1998 Dodge Dakota V6 heater only gets warm, I have replaced the thermostat. I have back flushed the heater core. The heater hose coming from near the thermostat gets hot, but the hose coming from the heater core going to the water pump only gets warm. The large hose coming from the thermostat is hot near the engine, but is only warm near the radiator. Is the water pump bad? If I open the radiator cap there is no signs of circulation. How do I check the water pump?Thanks,Gene

Have you checked the valve that shuts off the coolant when the heater is not required? It, or the pipes/ hoses to it, may be blocked, or the valve inoperative. I'd bet the coolant is not being allowed to circulate through the core by something. Backflushing doesn't guarantee the core isn't gunked up, either.

Q:how to replace water pump in a 96 F150?

1. drain coolant 2. remove engine fan and clutch assembly 3. remove radiator hose connection at water pump 4. remove water pump 5. clean water pump to engine mating surfaces 6. install water pump with water pump gasket 7. rest of installationin reverse order of removal

Q:What is the 10KV pump unit?

The 10KV pump unit, driven by a high voltage motor, is used for drawing water!

Q:My friend wants to buy a 90's somethin dodge avenger.( not sure what year) and the guy says the water pump is bad. Does the car have to be re timed when u replace the water pump?

Yep, but it's not as bad as you would think, but bad enough to take a weekend.

Q:Is the water lamp in the basement water pump fluorescent or waterproof?

No specific requirements are available

Q:I have a Stamas boat that I am in the middle of restoring. It has 2 chevy 350's, with borg warner (sp) tranny's, and v-drives. Anyway, it has standard water pumps to cool the engines, and it had 2 Sherwood pumps to circulate the water to cool the tranny's, and v-drives. First, I am using the boat in Lake Michigan only, the water is very cool year round since it is such a big body of fresh water. I was wondering if there was any recommendation on possibly using 2 electric pumps to circulate the water? If so, what would a good unit be? Second, the transmission coolers were brass, with a honey comb in the center for the ATS fluid to run through, and the water would run on the outside to cool the fluid. Is this a more effective way to cool the fluid than with those expensive brass fitting? Just checking before I spend a few hundred on them to see if a better way to cool my engine and tranny's, in all honestly though, I am more worried about effectiveness than cost.

You would be playing with fire to use electric pumps to cool the transmissions and v drives. I doubt they would put out the volume of cooling water needed to cool them and have enough extra volume just in case. Besides, the raw water pumps also would cool the engines and exhaust systems if they are raw water cooled or they would cool the anti freeze and exhaust and transmissions with heat exchangers and oil coolers. Those transmission coolers should be plumbed into the raw water system using the same water that flows through the engines. Not to mention the reliability of the electric pumps vs engine driven pumps.

Q:Rated power of three-phase pump4000W is a three-phase operating pump, the voltage is 380V, how to find the three-phase water pump current, and the formula is what?

Three phase water pump motor rated power 4000W is the output shaft power, divided by the motor efficiency (general 85%) is the input power, which is often mistaken. The electric power is =4000/0.85=4706WRated current = electric power /1.732x, rated voltage x, power factor =4706/1.732x380x0.8=8.94A (assuming power factor 0.8).The above three answers are all wrong.
