What causes a 1998 S-10 4 Cylinder to knock when it is in drive and gets hot about 210 degrees?

If it's a engine knock it could be low on coolant or have head damage...

Engine knock happens when an unbalanced air and fuel combination occurs inside of an engine cylinder. If the problem is not corrected the vehicle runs the risk of having a piston malfunction.

The knock sensor on the 1996 GMC Jimmy 4-wheel drive, 4.3 liter 6-cylinder is mounted in the engine block. Under the hood, look in the lower engine area on the passenger side, beneath the cylinder head.

Yes it can hurt your engine to drive with a bad knock sensor. The knock sensor should be replaced as soon as possible.

what causes the knock sensor code on a 2002 Kia Spectra. Thank You

The knock sensor are located in the valley between the cylinder heads on V6 and V8 engines V8s have two knock sensors

because their is no doorbell

Cold engine knock that goes away after warmup is usually piston slap. Worn pistons worn cylinder bores, wrong oil (too light) on a high mileage engine.

On a 2002 4.3, the knock sensor is located behind the driver side cylinder head. The knock sensor is very hard to reach.

I sould be on top of the block close to the firewall

It's screwed in the side of the engine facing the firewall.

The "knock sensors" for the Avalon 3.0 are facing the firewall on the engine block just below the cylinder head ,their are two knock sensors .

Yes, there is a knock sensor on the 2.3L. It is located on the rear driver's side of the cylinder head.

And engine knock is normally caused but I worn crankshaft bearing or rod bearing.

The manufacturer states throttle body and the intake manifold must be removed to access the knock sensor. The knock sensor is located on side of cylinder block.

Engine knock can be caused by several things. Carbon deposits in the engine can effectively raise the compression ratio of the cylinder. When accelerating, the cylinder gets filled with more fuel and air, and the higher compression ratio causes knocking. Other possible culprits could include spark plugs being too hot or your timing being off.

The knock sensor on a Passat is located on the side of the engine. It is just below the number two cylinder spark plug.

You can drive the car but if the engine should ping (knock) under load, the knock sensor won't be able to tell the computer to retard the timing. Excessive pinging can damage internal engine parts.

it can still knock and work but it wont last to long..its cylinder knock that's all.... your going to need a new motor!

A knock sensor is located in a specific area on the block or cylinder head in order to sense spark knock occuring and send a signal to the ECM to retard the timing. Relocating the knock sensor would defeat its purpose.

Pure luck! Don't knock it!

No, the knock sensor responds to spark knock caused by over advanced timing. A knock is a sudden increase in cylinder pressure caused by preignition of the air fuel mixture as the flame front moves out from the spark plug ignition point. pressure waves in the chamber crash into the piston or cylinder walls resulting in a sound known as a knock or ping. this is caused by using a fuel with a low octane rating, overheating, or over advanced timing. sometimes it can be caused by hot carbon deposits on the piston or cylinder head that raise compression.

They are located down in the engine block valley. Accessing the knock sensors requires cylinder head removal..........sorry.

the knock sensor detects pre detonation ans adjusts the timing to compensate

My first thought is that the wheel bearing is failing....replace it soon! The other idea is the front half shaft CV Joint is failing. ( the front wheel shaft on the side the noise comes from)
