Some automotive issues make themselves known instantly and in a big way. But signs of a bad water pump aren’t always so brash. A bad water pump can wreak havoc on your engine and should not be taken lightly. But how does a water pump go bad? Here’s a few bad water pump symptoms that can help you deduce if repairs are in order.
One of the most common symptoms of a bad water pump is a link hidden, please login to view from the water pump itself. Many water pumps are constructed with a weep hole below the pump drive shaft. Normally this weep hole is dry as the pump drive shaft seals keep the coolant at bay and away from the water pump bearings. But if the seal fails coolant can then seep past harming the water pump bearings and dripping out of the weep hole. The driver may notice a sweet smell of coolant cooking off the hot engine or a small puddle of coolant under the vehicle when parked. If the coolant is dripping on the accessory drive belt system there may be damp areas under the hood. If your vehicle develops a coolant leak or you find yourself adding coolant to keep it filled, check the area around the water pump just in case.
One of the common signs of bad water pump functionality is link hidden, please login to view. The pump may not leak coolant, but the pump mechanism itself may have failed. Over time the fins of the pump can actually wear down to the point where they are no longer moving coolant. Cavitation can eat away at the metal pump vanes and pump surfaces. Plastic water pump vanes can disintegrate over time as the plastic ages. This all adds up to coolant that is no longer moved through the engine block and into the radiator to be cooled, leading to overheating.
Water pumps have bearings that have to stand up to not only engine heat but also tension from the drive pulley. If you start to hear a grinding noise or high pitch squealing from the front of the engine, the water pump may be trying to tell you something. Try and rule out squealing belts by double checking belt condition and belt tension. Once you are sure the belt isn’t the cause try to pinpoint the source of the bad water pump noise. Be careful to not place any body parts near that rotating accessory drive system or the engine cooling fan. Simply stand in front of the running engine with the hood open and observe for a few minutes.
How to tell if water pump is bad can sometimes depend on the design of the engine. Some water pumps are buried inside the engine which makes it difficult to observe any problems. For example Ford Duratec V6 engines have the water pump located behind the timing cover. A leak from the water pump will allow coolant to mix with oil around the timing chains but the leak will not be visible on the outside of the engine. Checking the engine oil regularly and looking for an increase in oil level (due to coolant collecting in the oil pan) or a milkshake-like oil appearance are signs of possible symptoms of a bad water pump. Unfortunately these can also be signs of a bad cylinder head gasket, so further investigation will be required.
Any of these symptoms should be taken seriously and further investigation as to the source of the problem. If a bad water pump is diagnosed, it should be link hidden, please login to view. Don’t risk ruining an engine by putting off a repair that is relatively minor.

link hidden, please login to view Why is catalytic converter matter?
The catalytic converter belongs to the exhaust system of the vehicle. During use, they may be contaminated, blocked, or physically damaged, which will lead to poor engine performance, and in severe cases, the engine will stop.
What can cause damage to the catalytic converter?
Some pollutants can damage the catalytic converter, such as lead-containing gas, engine coolant and engine oil, among which the engine coolant can leak into the combustion system due to the failure of the cylinder head gasket. These liquids can clog the catalytic converter, thereby restricting the passage of exhaust gas.
If the spark plug does not ignite or the exhaust valve is leaking, there is too much unburned gas, and the catalytic converter may overheat.
What happens when the catalytic converter goes bad?
Engine performance is slow The exhausted gas is black smoke with the smell of sulfur or rotten eggs The underside of the car is overheated
How to mainitain catalytic converter?
Maintain your vehicleregularly. Keep your exhaust, emission and combustion systems in good condition, which can effectively reduce the probability of catalytic converter damage Check the engine lights regularly.

I have been a mechanic for many years. I used to buy Napa Auto Parts almost always. I felt the parts were good quality, although more expensive than others. It does not pay to install poor quality parts on a car, they come back, and bite you! Unfortunately, a few years ago it seems Napa changed their policy on quality. This happened around the time they totally changed the on-line site. Around the same time, I started looking at Rock Auto on-line. Rock Auto offers each part by a few different manufacturers, quality levels, and prices. I started noticing that despite Napa still charging higher prices, they were now supplying the cheapest, lowest quality parts instead of the better quality they were known for. Given that, why would a person order from Napa, when Rock Auto is surprisingly lower priced, and you have a quality level choice . Napa seems to be riding on their previous well known name, while keeping the prices artificially high.
Some prime examples of this is, I purchased a starter solenoid, (eckland, Napa's electrical brand), as a preventative measure. The third start-up, after installing, the solenoid froze in the on position, with key off, and kept the starter spinning and engaged until I could unhook one battery terminal. Burned up the relay, starter, and a couple wires. I purchased a rebuilt alternator, took it from the box, and turned it, it felt rough turning, as if there was dirt in the bearing race or defective bearing components. I purchased Napa's best fuel pump, and it was very noisy from day one. I purchased a set of Napa Branded, 2 ton each, jack stands. One of them had a defective casting that would not allow the stop to lock in place. Although it seemed it locked, when weight was applied, it fell. I purchased rebuilt Ford Front calipers from Napa, and with in one year, the unplated soft steel bleeder screws has rusted solid to the caliper!
Are other people seeing this too??

I have 09 Tacoma. Their OEM pads are great for stopping power, but they leave a dark residue on the wheel cover. Any of you gentlemen have any suggs?
I typically get 4o,000 plus out of a set of OEM pads. Like I said, they stop good, and they're easy on the rotors.
Thanks in advance.
