This particular bottle is knows as a degas bottle. The reason it has a strange shape is two fold. First, the bottle needs to fit somewhere and the shape helps that. Second and more important is that these degas bottles hold pressure. The shape reinforces the bottle so that it does not explode. In cooling systems with degas bottles the coolant does not ...

I do not understand why the coolant system needs a bleed screw at all Because air pockets. Filling up coolant doesn't necessitate that the entire system will be filled with coolant. There are parts of your cooling system that will trap air when it is refilled. The bleed screw is a means to expel the trapped air from the system. I repeatedly fill ...

Simple And Technical Definition Of Coolant From a technician's standpoint "engine coolant" would be referring to the 50/50 mix of ethylene/polypropylene glycol and water. From an engineers standpoint engine coolant would TECHNICALLY be anything that assists the system in the cooling process. So, in this case you could refer to the fans, oil, and Anti-freeze ...

I can see a few reasons to do this: The weather in some places will be so cold that even with the thermostat fully closed the cooling system isn't able to warm the engine up to operating temperatures. Inhibiting air flow through the radiator will reduce the amount of heat rejected to the surroundings, allowing the engine to get up to temperature. The cold ...

What is engine coolant? Engine coolant is a water and antifreeze solution. Because water has good properties as a coolant, antifreeze is used in internal combustion engines and other heat transfer applications, such as HVAC chillers and solar water heaters. The purpose of antifreeze is to prevent a rigid enclosure from bursting due to expansion when ...

I completely forgot about the draining part, but have no time left. So, here about he antifreeze part. May be, I'll write more later It may work, but is not recommended. Freezing point Antifreeze freezes at -15°C. To prevent antifreeze from freezing, add some water, because water is antifreeze for antifreeze. OK, I had some fun... Seriously, here a ...

It sounds from the comments that you have eliminated belt slip as the culprit due to the sound of the squeak (and lack of squeal). If you can pinpoint the squeaking to one specific pulley, it is likely the bearings for that pulley are on their last legs. Bearings perform better under heavier loads, which could explain why the squeak goes away at higher ...

You get less cooling. If the radiator is only 1/2 way full you have water in contact with cooling fins for 1/2 the time and 1/2 the cooling. The fluid is pumped from bottom so it will continue to flow. Eventually the water is hot enough that the engine turns it to steam. Once you empty the radiator then zero cooling as nothing is pumping.

Water flow will stop and the heat will not be able to be transferred out of the engine block. Engines cooling systems are very intricate and feature "pockets" depending on how much cooling is needed for a given area. A lack of coolant means that the system will not be able to be pressurized by the pump and the coolant will not flow. Disadvantages: ...

I've worked at automotive dealerships for over 30 years. Bearings are made of soft metals such as copper and babbitt so that they will not damage crank journals if contact is made. In earlier days, having coolant in the oil was an inconvenience. You may want to run a few quarts of ATF through an engine, then change the oil twice, in quick succession. Over ...
