Hi, Anonymous and the usual suspects are:
1. Engine oil level and SAE weight are too low or not circulating.
2. Insufficient or blocked air flow over the engine.
3. Heavy combustion chamber carbon deposits.
4. Ignition timing retarded due to faulty MAP, CKP, or CMP sensor.
5. Carburetor jetted too lean.
6. Leaking intake or exhaust valve.
7. Water coolant old or low change every two years.
8. Water pump failure.
9. Radiator clogged, cap loose or malfunctioning.
10. Radiator fans not coming on.
11. Clutch slipping, brakes dragging, heavy load, towing a trailer etc.
12. Idling too long without moving.
13. For constant hot weather temperatures, mountain, or desert riding conditions consider adding an oil cooler and or cylinder head cooler.

How to change the water pump on 2000saturnsl2

Here is that info.
Have a full set of Torx sockets inaddition to the normal ones.

Support the engine.
Remove the air filter box.
Remove the front engine mount.
Pick an order here for the belt and pullies.

What ever will work for you. This is because the serpentine belt will llikely not stop the pullies from spinning. A flat pry bar through two of the bolts on the water and PS pullies while you loosen the third works better. Be careful as the bolt heads round easily.

Remove the water pump pulley.
Remove the power steering pulley.
Remove the serpentine belt.
Remove the lower crank pulley. Outer bolts not the center one
Remove the belt tensioner.
Remove the timing belt covers.
Put a coolant catch pan under the front of the engine.
Remove the water pump.
Clean the sealing surfaces. install the new pump anbd reinsatll the removed parts.
Fill the cooling system and hope that the heater core did not drain. The heater core tends to air lock if it is drained of coolant. This is why the coolant is best drained by removing the water pump and not draining the rad and the entire system.
Run the engine until you have good heat in the car with out having to rev the engine.
Check and top the coolant level as needed

Hi need help I've got a 2002 wr 426f but need new frame I can buy a yzf 250 2002 frame but not sure if it will fit I know ill lose my kick stand

Yes the YZ frame will work perfect.
The main difference in a WR to a YZ is the extra weight that the flywheel has on the WR's engine,other than that the bikes are about identical.
Good luck,Gary

Hello, I have a 2002 Yamaha 426f and recently changed the oil and filter, I noticed that there was a small amount of metal shaving in the filter, bike has approx. 400 miles on it, is the motor headed for...

That is what an oil filter is for. Some people fit magnetic sump plugs to catch the bits of metal that drop into the bottom of the sump.
Don't worry, it's normal.

I have a problem with my yamaha yz 426f, i just get it from a mechanic after complete rebuild (new piston, bearings...everything in a machine) the compresion is very strong because engine didnt run even 5...

Bring it back .. work should be under warranty of some sort. Also if the engine is running but stalling due to fouled plug then maybe the oil injector is not adjusted properly or the oil/fuel mix is not right for some reason.

How do i change the water pump on a 2000 dodge,grand caravan

Removing and changing the water pump on a 2000 Grand Caravan should only be done if your van has a 3.3 liter or 3.8 liter V6 engine. On any other engine types, including four-cylinder engines, you must remove the timing belt from the engine to access the water pump, which is a dangerous task that can mess up the engine if attempted by an amateur.
The procedure is as follows:------------- The water pump is responsible for sending the engine coolant to the engine.First of all remove the serpentine belt then remove the plastic cove on the passenger side behind the wheel. You will have to remove the pulley. Once the pulley is removed unbolt the water pump and remove it. Clean the surfaces and install new pump. Draining the coolant and replacing it is advisable.
Drain the engine coolant, twisting and removing the drain plug at the bottom of the radiator
-------------------Thats it.

Changing water pump 2000 ford focus

Changing a water pump is pretty basic. Since the coolant system is a closed system you only need to be concerned with that system. For instance you since you have to mess around with it anyway you might as well change the thermostat and flush the coolant system. Make sure your radiator hoses are in good shape and that's about it.
If you have basic mechanical skills and tools you will have no problem replacing a water pump.

As far as information with the actual replacement there are a number of experts here including myself that could explain how to do it.
However no matter how good our explanations are it just can't compare to a good repair manual.
A repair manual for your car at Auto Zone would likely cost between $12 and $15. It is a great investment if you are going to keep your car for any length of time. When you sell, it shows the buyer you took the time to maintain and repair it right.
I personally like Haynes Manuals.
I hope this helps.

My Yz 426F and it won`t start at all, changed the plug and it still won`t start

HELLO; Now, pull the plug out reinstall it on the ing. cable and short it out on the head while cranking the motor over ,look for a nice crisp spark. If you have one, check for fuel flow from your tank to the carb. Check that and if nothing, write back and we will go from there. GOOD LUCK.
