In various combinations specific to each model, EfficientDynamics technologies such as Brake Energy Regeneration, on - demand control of ancillaries such
as the coolant pump, the fuel pump and the a / c compressor, as well as active air flap control and tires with minimum rolling resistance will be used.
Not exact matches
It is also more cost effective and reduces energy consumption
as the system does not require huge
pumps to generate the flow of the
coolant.
So has securing delivery on certain components, such
as reactor
coolant pumps, because they are being produced for the first time.
In the case of the Olkiluoto 3 EPR, he notes that safety engineers designed a reactor with more
pumps and valves to prevent the loss of any
coolant, «but there wasn't
as much effort into designing for construction,» which is driving the overruns.
You hear unfamiliar sounds, like the gushing
coolant flow that keeps the batteries healthy, the distant hum of the heat
pump that also serves
as the air - conditioning, the subdued whine of the regenerative brakes, and the much more intense mix of wind and road noise.
It would not be the water
pump as in most every engine I've seen there isn't any oil passages going to it, just
coolant.
The
coolant is circulated by a
pump known
as the «water
pump».
As the
coolant is moved around the system by the water
pump, it passes through two main components:
I believe most modern Volkswagen based engines since
as far back
as the 1992 VR6 engine have a secondary water
pump which circulates
coolant after the engine is shut off.
You're changing the water
pump, so that's a good opportunity to do a
coolant flush
as well.
Considering the age of the car, it could be
as simple
as a cracked or loose
coolant hose (fairly cheap), or a failing water
pump (not very cheap).
EDIT:
As for the low
coolant, if possible, you should inspect the
coolant hoses and water
pump for leaks, or have a mechanic do the same.
I'm concerned they didn't source a new oil
pump - without it, parts of the engine or
coolant system may overheat and this could lead to leaks such
as the ones you have seen.
Map - controlled electrically operated continued
coolant circulation
pump - V51
as back - up for mechanical water
pump and for continued
coolant circulation
Best guess based on your explanation: First the water
pump quit / died, then engine overheated
as a result and it remained running overly - hot for sometime thereafter, which (likely) led to head gasket failure, which resulted with
coolant in the oil and the performance symptoms.
As per the picture below,
coolant is oozing out of the front of the engine, above the water
pump (replaced last fall) and below the thermostat.
Gross horsepower is obtained by a dynamometer test of an engine equipped only with the built - in accessories essential to its operation, such
as fuel
pump, oil
pump,
coolant pump and built - in emissions - control equipment
I would check the
coolant reservoir to verify its full, if its low look for leaks around the water
pump, radiator, hoses and around the intake
as coolant runs through certain parts of it.
Also doing their bit to seal the exceptionally fine balance between driving pleasure and fuel consumption for this output class are a
coolant pump that operates only
as necessary, a map - controlled oil
pump, Electric Power Steering, the Auto Start Stop function, Brake Energy Regeneration and various other solutions developed under the banner of BMW EfficientDynamics.
Critical parts like fuel filter, engine
coolant, brake fluid and water
pump drive belt have different timings
as listed below:
Coolant leaks may come from a variety of places such
as any of the hoses that go to or from the radiator to the motor, the thermostat housing, the water
pump or potentially the radiator itself.
Hello - if the
coolant temperature is truly getting
as hot
as you describe, and the thermostat and water
pump are transferring that heat to the radiator, the
coolant fan temperature switch (https://www.yourmechanic.com/services/thermo-
coolant-fan-switch-replacement), or it's relay and wiring, are malfunctioning...
There is water cooling
as electrical systems run hot too, and on the Soul EV there's a heat
pump system that recovers waste heat from the
coolant to the cabin climate control system.
Examples include the demand - controlled
coolant pump, the map - controlled oil
pump as well
as electromechanical power steering, whose electric motor only uses energy when power steering is required.
Intelligent energy management is further enhanced by the ancillary units, such
as the on - demand
coolant pump, the electronically controlled oil
pump and the Electric Power Steering system (EPS), which only consumes power when steering assistance is actually required.
