Kind of. There are water jackets inside the engine block and usually the heads of a liquid-cooled engine Water (or coolant) will either flow from the block to the head to the radiator, or from the radiator through the head to the block (a reverse flow design). The latter is better because it cools the heads first and helps prevent detonation. It also reduces thermal shock to the engine block.
In the radiator, coolant recover tank, heater core, and inside the engine water jacket.
Assuming you mean coolant (shouldn't run straight water), the coolant is pumped through the water jacket by means of the water pump. This is part of the cooling process for the engine. The knock sensor happens to be where the drain plug used to be.
IN THE WATER JACKET.
You're thinking of a block heater. It plugs in to shore power, and energizes an element attached to the engine block (some have dual elements, and the second one will go to the oil pan) to heat the coolant in the water jacket so that it doesn't freeze. In turn, once the engine is running, this heated coolant will get circulated to the rest of the system, and begin thawing out the remaining coolant.Although a block heater doesn't actually circulate the coolant when the engine is at rest, there is a type available which is essentially an electric pump which will pump coolant through a heating element and back into the cooling system... I've only ever seen it on really specialized heavy equipment.
Water jackets are the hollowed out spaces in the engine block and head through which the coolant flows. In water jackets, waste heat generated by the engine is picked up by the coolant. After flowing through the water jackets, water flows through the radiator. The radiator is basically a heat exchanger which, through a system of tubes and fins, transfers this waste heat from the coolant to the atmosphere. After the water is cooled in the radiator, it flows back into the water jackets of the engine to pick up more waste heat.
No, and if your vehicle doesn't have a coolant filter, it will introduce a foreign matter into your engine and water pump, which will compromise your water pump and possibly clog up the coolant jacket. Whoever told you to do this - never take advice from them on anything, ever.
In automotive engine terms, the area between the cylinders and the block where coolant flows is considered the water jacket.
Unplug electric connector. Sensor is in water jacket so you will need to catch coolant after removing sensor. Properly dispose of old coolant. Install new sensor and just make a little snug (with open-end wrench)- do NOT over tighten. Install electric connector and top off coolant.
A blown head gasket could allow coolant to enter the combustion chamber from the water jacket. The coolant probably is running out the exhaust on first start-up. More often, you will notice the coolant being pumped out of the overflow as the exhaust gas pressurizes the coolant. You should look for this symptom when the engine warms up. Coolant in the exhaust on start-up and then the coolant overpressure overflow from the expansion tank or radiator happening together is almost sure indication of the head gasket failure.
For a short while depending on where the crack is. Most likely it is in the water jacket from being frozen. If the crack is to the outside, the coolant will leak out and the engine over heat. Wherever the crack is, it is gong to let coolant, oil or exhaust mix in some manner and which ever it is will not be good.
1. Water pump possibly weak, failing or leaking coolant 2. Thermostat is not operating correctly or the housing for it is leaking coolant. 3. The water jacket in the engine block has possible restrictions or leaks somewhere. Head gasket breach...leaking coolant? Freeze plugs on side of block? 4. The radiator hoses (upper or lower) have issues and are leaking. What area of the engine compartment is the STEAMING COOLANT coming from? Top, Bottom, Front, Back, Radiator, Engine etc. (This info is important for anyone to be able to help diagnose the problem without being able to ACTUALLY see it).
Yes you can. A cracked block does not necessarily mean the car will overheat. If a block is cracked at a coolant jacket then coolant will leak out and the car will overheat if the leak is bad enough. If the leak is not very major or if the crack is at a point that does not have a coolant jacket then it will not overheat. A cracked block could leak oil, compressed air/fuel, coolant, or nothing at all and still be cracked. -R. Mesyef
