Q:i'm changing the tyming belt the vehicle has done 120,000 km should i replace water pump as well
no set mileage. no service interval for that above a visual inspection. should i replace water pump as well YES!!!!!!!!! water pumps are a consumable item. don't wanna do that much labor again soon. i strongly suggest you pay the extra bucks and get a toyota AISIN pump. it will last longer than any after market one hands down. do check for a front main crank seal leak as well. it's part of the oil pump. personally, if it were me, i'd do all three. belt, pump (from toy will be pricey, but worth it), and reseal kit for the front main (is 10-15 bucks and not much more labor).
Q:Ok, so I have a 1997 3.8 liter ford mustang. I was driving home from work the other day, when temp gauge started to go up. I brought it to mechanic, and he said it was a bad water pump, due to bad antifreeze. So I am getting a new pump, and an antifreeze flush. My question is that since it overheated, will there be any damage to the engine? The temperature gauge never hit the red, and smoke never came out. I had to drive it for approx 15-20 miles when it started to overheat, and the temp gauge was bouncing from hot to normal.
Depending on how long you overheated your car and how hot it was.
Q:Can someone please post a picture of how to find a Water Pump on a 1992 Dodge Spirit with a K2.5L Engine, it would be much appreciated. :)
yea you might want to post in the maintenance section or dodge section....
Q:i have well water. suddenly i'm getting more pressure in my water. I have a well siofterner system. does anyone know what could be causing more pressure to come out from the water?/ thanks alot.
too much pressure in your pressure tank bleed some air out. reset pressure.
Q:A pump, the flow rate of 30T/H per hour, lift 30 meters, should be allocated more power motor?
The actual use of power should be at least 5.5kW, I did not find 30t/H lift 30 meters of the water pump, and only he approached the model, supporting a larger power, and will not increase the power consumption
Q:The water is being put in because it was overheating. We changed the thermostat and everything and it got better, but about a month later it started overheating again and now it is leaking water bad from underneath the car. Whatever is leaking is covered by a shield thing. Im not sure what it is, and I dont want to replace it before I know if thats really what it is. Any help would be greatly appreciated.
If the leak is on the passenger side of the car (near the tire) then it is most likely your water pump. It is driven by the serpentine belt that drives most of the visible components on the passenger side of the engine. (power steering, A/C, Alternator etc) To check it, you need to look UNDER the water pump, it has a weep hole. If this small (1/8) hole is wet, or shows signs of having been leaking (like discoloration or rust) then your waterpump seals or bearings are going. The unit must be replaced. This should also fix your over heating problems. If the leak is near the back-center of the engine, then it may be a frost plug (also called a freeze plug) these are designed to pop if the enging coolant freezes to prevent damage to the engine block, they can also be opened if the engine over heats. Be careful when replacing this plug, if you drive it INTO the engine, you will have to dismantle the engine to get it out again. On the plus side, you can get rubber plugs that are easy to install and quite inexpensive. I'd place the water pump as the most likely problem.
Q:Hello, I'm having an issue with grinding/metallic noise from engine bay. Alternator was replaced today and didn't fix. However, when I got the car back from the garage the oil level indicator is saying quot;inactivequot;. I seem to find some answers on the web that say the oil level indicator is in some way connected to the water pump. Car has 95k miles on and I doubt it had been changed. Could this be the cause of the noise? And could anyone possibly tell me which pulley it is on the belt? Many thanks for your time :)
Alternator replaced? Will you be getting credit back for that? Anyway, at 95k it's almost about time to do a full preventive maintenance thing. That includes the water pump, belts, radiator hoses, I would do the tensioner and idle pulley too since one is there already. Would replace the radiator expansion tank too. Change the spark plug and valve cover gasket too while you are at it. The spark plug can be done separately, but it's time to replace them.
Q:The dealership wants nearly $500. to replace the water pump in our 2002 Tahoe (5.3) it's leaking from the weep hole. I'm somewhat mechanically declined, what precautions will I need to know and any special tools to do the job myself? I've done a few water pumps back in the 1980's that didn't leak Thank you
You just need basic tools and a little knowledge. Since you've changed them before, you should have no problem. The Tahoe water pump hasn't changed that much. It's still on the front of the engine.
Q:Why should the water inlet of water pump be fitted with reducer?
Increasing the pipe diameter can reduce the resistance loss along the path and reduce the suction vacuum of the pump! Before the inlet of the pump is a big diameter, when you reach the suction port, and the pump inlet diameter to be consistent, so the use of reducer joints!
Q:I'm trying to sell my 97 Ford Escort. It needs a water pump but I have no idea what the cost is. I just want to know so I can post an estimate of how much it costs on the site I'm selling it on.
We all know what you want to use that water pump for.
