If cranial leaks last more than seven days, the chances of developing meningitis are significantly higher. [55] Spinal CSF leaks cannot result in meningitis due to the sterile conditions of the leak site. [24] When a CSF leak occurs at the temporal bone, surgery becomes necessary in order to prevent infection and repair the leak. [56]
Once the coolant absorbs the heat from the engine it continues its flow to the radiator. The radiator transfers heat from the coolant to the passing air. Radiators are also used to cool automatic transmission fluids, air conditioner refrigerant, intake air, and sometimes to cool motor oil or power steering fluid. A radiator is typically mounted ...
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 and water in the engine boiled. However, since water loss led to overheat and further water loss from boil-over, the original water loss was hidden.
First, the head bolts simply weren't numerous or strong enough for the diesel's high compression ratio, so they started blowing head gaskets. 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.
A backup radiator circuit on the Nauka module of the Russian-controlled portion of the ISS has sprung a leak. The crew is not in any danger, according to Roscosmos.
Sodium silicate can be used to fill gaps in the head gasket of an engine. This is especially useful for aluminium alloy cylinder heads, which are sensitive to thermally induced surface deflection. Sodium silicate is added to the cooling system through the radiator and allowed to circulate. When the sodium silicate reaches its "conversion ...

The result was deep pits that could form and penetrate the engine head in a matter of hours when the engine was running at high load and high speed. These effects could largely be avoided by the use of organic corrosion inhibitors or (preferably) by designing the engine head in such a way as to avoid certain cavitation inducing conditions.
