Water circulation is aided by a rotary pump that has only a slight effect, having to work over such a wide range of speeds that its impeller has only a minimal effect as a pump. While running the leaking pump seal drained cooling water to a level where the pump could no longer return water to the top of the radiator, so water circulation ceased ...
Second big problem: GM's cost-cutters decided not to fit a water separator. Unlike gasoline, diesel fuel is subject to water condensation – hence the need for a water separator. Without one, water in the fuel becomes water in the engine, where it can rust either the cylinders or the complicated mechanical fuel injection pump.
In automobiles and motorcycles with a liquid-cooled internal combustion engine, a radiator is connected to channels running through the engine and cylinder head, through which a liquid is pumped by a coolant pump. This liquid may be water (in climates where water is unlikely to freeze), but is more commonly a mixture of water and antifreeze in ...
Honda issued a recall that covers 720,810 vehicles due to a potential issue with the fuel pump. ... the 2025 Civic and Civic Hybrid, and the 2023–2025 CR-V Hybrid. ...
Honda is recalling 2.6 million cars, SUVs, vans and pickups in the United States because the fuel pump could fail. If that happens while driving, the vehicle could suddenly lose power.
Water pump seal lubricant is also added. Antifreeze was developed to overcome the shortcomings of water as a heat transfer fluid . On the other hand, if the engine coolant gets too hot, it might boil while inside the engine, causing voids (pockets of steam), leading to localized hot spots and the catastrophic failure of the engine.
It is a myth that in certain circumstances, a lifter can "pump up" and create negative valve clearance. The engine oil pump cannot generate enough pressure to cause "pump-up". The problem is due to weak valve springs which permit float at high engine speeds. The followers attempt to take up what they see as extra clearance.
Breast cancer was the only type for which treatment advances prevented more deaths. Quitting smoking was found to be the most beneficial prevention strategy overall, credited for averting 3.45 ...
