Seal is going bad, as the other post stated. IF your bike is older than 2005 then replace the water pump impeller with an 06 model or drill a 3mm hole in between 2 fins. without the hole the impeller builds too much pressure on the back side pushing water through the seal.

My Subaru. 2000 forester overheats after running on the interstate for a stretch . It seems fine while running around in traffic . Now when it does over heat I let it cool down and my water level is low so...

I am thinking blown head gasket either as the initial cause or because of the overheating. do a compression test on cylinders to rule out blown headgasket, check water pump by leaving cap off and watching flow of cooling system be safe at all times though check waterpump weep hole for leaks also check thermostat operation make sure both upper and lower radiator hoses are equally warm and one of them is not cold which usually means thermostat is stuck in closed position.

04 TAHOE Front A/C works great, Rear A/C blows warm. Seems like something isnt shutting the flow of hot water to the back??

Hi Jason.
Sounds like you are on the right track with the flow of hot coolant not stopping. Check your heater control valve to make sure it is stopping the flow of coolant through the rear heater core. Let me know. Hope this helps.

Does a water pump go out all at once or can it intermittent spells where it works and then does not before it goes out for good

Most of the time a water pump give a warning when it is about to go. The warning is a small coolant leak at what is called a weep hole in the water pump itself. This weep hole is to let us know when the seal is going bad or a bearing has worn to it's limit. Most water pumps now days do not break an impeller, where everything else is in good shape and no water is being moved. If you have been seeing a coolant leak at or around the passenger side engine compartment, that has gotten worse, as you drive and she gets hot. That might be your water pump. Other wise you may have some other problem. Such as, the cooling fan not coming on when is should. Bad coolant thermostat, the thermostat would be the most common problem, (most likely to cause overheating problems). The water pump is driven by your timing belt an will need to be replaced also if the pump is found to be bad. to check your cooling fan circuit, start with the fuse box. Look for any blown fuses. Next check your fan itself, It should run when the engine is warm and also should come on with the A/C on. If you engine is very warm, w/ A/C off, the fan should cycle on/off to keep air flow over the rad. If you can drive for 20 miles non stop and your gage stays in the normal zone then have to sit in stop/go traffic and the gage goes up in the red until you move again this is an indication that the fan is not coming on when it should. Have that check first. Hope this helps FixYa up.

My car overheated today,we put cold water in the overflow,to get home,it seemed ok,it was about a 10 minute ride,and it started to go up again,we dont think the fan is coming on,he checked the main area...

Could be a faulty water pump, clogged or stuck Thermostat or clogged radiator. Once the engine cools down remove the radiator cap then start the engine and wait for it to warm up to operating temperature. At operating temp you should be able to see the fluid in the radiator circulate. If you don't then you need to let the engine cool again and remove the thermostat or replace it. And run the same test again. If you still don't see the fluid circulate then replace the water pump.

Why wont my 99 chevy blazer temperature warm up?

You may have vapour lock in your heater lines. Start engine, put heat lever on high, disconnect one of the lines on your heater core, the one on the flow out side, & see if you have any air coming out. Once antifreese comes out stick line back on & retighten clamp. Make sure your cooling system is topped off. Also your water pump may not be functionihg to it's maximum. Take rad cap off cold & view flow rate. If inadequate you may have to replace the water pump. Good luck!

2004 chrysler 300m 3.5L waterpump location and does it run off the timing belt/chain

Yes the water pump does run of the timing belt system.
Directly from the service manual:

The 3.5L water pump has a die cast aluminum
housing and a plastic swept vane impeller. It bolts
directly to the right rear timing belt cover using an
O-ring for sealing. The water pump is
driven by the engine timing belt.

The water pump on all models can be replaced
without discharging the air conditioning system.

NOTE: It is normal for the water pump to weep a
small amount of coolant from the weep hole (black
stain on water pump body). Do not replace the
water pump if this condition exists. Replace the
water pump if a heavy deposit or a steady flow of
engine coolant is evident on water pump body from
the weep hole (shaft seal failure). Be sure to perform
a thorough analysis before replacing water

(1) Drain cooling system (Refer to 7 - COOLING -

(2) Remove accessory drive belts (Refer to 7 -

NOTE: The water pump is driven by the timing belt.

(3) Remove engine timing belt (Refer to 9 -

(4) Remove water pump mounting bolts (Fig. 31).
Note position of longer bolt for proper re-installation.

(5) Remove water pump body from engine

Do not know how to work/maintain swamp cooler

Make sure you have water to the unit, the water pump is on and the fan is working. No water=no cooling.

Refrigerator side stops cooling

Drain stopped up.
Take out the bottom drawer in the freezer, look at the back wall and you should get a partial view of the bottom of the cooling coils. Directly below these coils is the drain area. You may need a light to see the drain hole. If this area is covered with ice then a hair dryer will help clear this so you can see the drain hole.
I have some O2 tubing that I put down the drain to clear any cloggs. Also, I seal the top of the drain hole around the O2 tubing with tape and use the air from my lungs to clear the drain tube. Pour a little water down this drain hole to make sure it’s clear.
