It sounds like you're asking several questions at the same time. In terms of the symptoms of failure, you don't give a lot of information about your specific car. However, some basics always apply: leaks (especially at the bottom of the timing belt cover) and basic failure to move the coolant (are you overheating this summer?). In terms of cost, you're ...

The lifespan of a replaced waterpump will vary with quality. You have no way of knowing what type of pump you paid for. Was it a factory new pump, an aftermarket new pump, rebuilt pump or remanufactured pump. Factory pump is an exact replacement of what the car came with High quality new aftermarket pump may include improvements to the original design ...

Impossible to say. I can only offer my own anecdotal Toyota experience. I had to have the engine rebuilt on my MR2 at 180,000 miles (due to oil pump failure). The original water pump was still working fine, no leaks, no problems at all at that point. However, since the whole engine was out and being rebuilt, we replaced it. At my 240,000 mile timing ...

If this looks like your water pump, then yes you can: The tilt in the pulley is caused not from a broke shaft, but from a worn bushing which the shaft rides upon. This is just one of the symptoms which shows up when the pump is dying a short miserable death. As the bushing wears out, there is created more and more space (slop) which allows the shaft to ...

It doesn't sound like a fuel line problem ( though there's a small small chance it's a fuel pump ), it sounds like your engine isn't getting enough air on one end or the other. It might be a dirty air filter, or it might be a clogged cat or bad O2 sensor. Sometimes it's easy to tell if the cat is clogged, it will get extra hot and turn red and that's your ...

Hopefully your mechanic would pressure test the water pump before replacing it to determine if it's really bad. Having no heat is usually a symptom of a stuck open thermostat, but if that was the case, your temp gauge would not indicate hot...maybe a clogged heater core? Did your heater core get flushed? That wouldn't explain the temp gauge reading hot, ...

The water pump is a mechanical pump that is one of the belt driven devices in your engine. This pump is what circulates the coolant (when the parts are referred to for water, they mean coolant. Water hoses, water outlet, water inlet, water pump, etc are all carrying coolant). The water outlet is simply a pipe, on one end of it is the engine block, on the ...

Cheap waterpumps - like any mechanical component - can fail quickly, sometimes this happens. Do you have a warranty on the replacement pump? Also, are you certain that the water pump has been replaced? It's not too uncommon for some mechanics to skip the water pump replacement because the pump "still looks good" only for it to fail shortly after the timing ...

The 3.8 Natural Aspirated Engine was a rather solid design and were rarely known to blow head gaskets. Their weak point seemed to be the plastic Intake Manifold. Here are the three possible causes to your issue. If you are 100% sure that it's oil in the coolant then remove the intake manifold and check the Intake Manifold Gaskets upper and lower for any ...

It's likely that the oil cooler is leaking if the vehicle is equipped will have one. Look for metal lines running into the radiator tank. If you have an automatic transmission there will be two sets of lines on each tank of the radiator.

Turns out it was the water pump. Jim at Watson Automotive in Thetford VT replaced it ($400) and it's not stalled or flooded since. In the question I left out one clue that Jim used — a belt was squeaking. He found that was from a leak of radiator fluid from the water pump. Jim theorizes that low coolant caused portions of the engine to get too ...

The water pump pulley is usually bolted to the pump, and can be re-used.

As both 'mikes' and 'Paulster2' thought, the radiator system was simply burping. It took much more coolant than I expected, ~2 refills to the middle of the coolant tank. Might have been some combination of the rapidly cooling weather coupled with the water pump replacement, but at any rate, coolant level is perfect now without any intervention other than ...

Water pumps are expected to last at least as long as the timing belt change interval. It's a relatively cheap part in a high labor location, so it's common to replace it with the timing belt just to potentially save on labor later on. It shouldn't fail so rapidly, however, it is possible. Bad parts and early failures do happen sometimes.

Thanks for the responce. I did run the steel seal with the 1 spark plugged removed for 1 hour. not only did it bring the compression back to that cyl but im not getting exhaust gasses in my coolant anymore. I recommend steel seal for any blow headgasket issues. not only do they stand behind their product IT WORKS!!!. also found the person i bought the car ...

This is almost surely a blown head gasket. A compression test might not even show it, especially if the leak only happens under the pressure of combustion (which is much higher than just the compression from the cylinder moving). You could get a block check kit (which works by pulling fumes from the radiator opening through pH test fluid to determine if ...

I drive a 2006 Camry, and just crossed 95K miles. Although the pump did not fail, it did start foaming around the gasket so I had that taken care of before it got bad. I foresee seals, and gasket failing before the pump does.
