  • A thermostat gasket, typically made from rubber or silicone, is placed between the thermostat housing and the engine block. Its primary function is to create a watertight seal, preventing coolant from leaking out and ensuring a smooth flow through the engine. It acts as a barrier, maintaining the integrity of the cooling system and preventing any contamination that could disrupt the delicate balance of temperature within the engine.

  • A typical oil seal consists of three common parts: an outer ring, the sealing element, and a spring. The exterior metal ring component provides strength and rigidity to the oil seal in the bore or recessed groove. Attached to that ring is the sealing element. This flexible interior component of the oil seal, the O-ring, prevents any fluid leaks between the shaft and housing. A spring ensures the constant pressure that deforms the O-ring, creating a reliable seal while maintaining radial force on the shaft.

  • The front hub oil seal is responsible for keeping the oil inside the front hub and preventing it from leaking out. This seal is typically made of rubber or a similar material that is designed to withstand the heat and pressure that can build up in the front hub during operation. Over time, the front hub oil seal can wear out or become damaged, leading to oil leaks and potential damage to the front hub components.

  • Polyacrylate Rubber (PA): PA is a go-to material for high surface speed environments as it has better heat resistance than nitrile. It performs optimally within a temperature range of -4 to 302°F (-20 to 150°C). It is incompatible with water or temperatures below -4°F (20°C).

  • Vulcanizates of several fluoroelastomers, listed in Table 14.1, were exposed to a standard 5W-30 engine oil, ASTM Service Fluid 105, for up to 6 weeks at 150°C (302°F).5 The oil was changed weekly, but was not aerated. Retained elongation was measured after exposure for 1, 2, 3, and 6 weeks; data are shown in Fig. 14.3. The results indicate that bisphenol-cured FKM-A500 VDF/HFP copolymer, FKM-B600 VDF/HFP/TFE terpolymer, and peroxide-cured FEPM-7456 TFE/P/VDF terpolymer lost most of their original elongation over the course of the test exposure, indicating considerable additional cross-linking occurred by reaction with amine- and phenol-containing oil additives. The other fluoroelastomers showed better retention of elongation, being much less susceptible to additional crosslinking. Note that FEPM-7456 contains a high level of VDF (about 30%), while FEPM-7506 contains a relatively low VDF level (10–15%) to serve as cure site for bisphenol curing. The other FEPM types contain no VDF.

  • Iridium spark plugs have gained popularity in the automotive industry due to their exceptional durability, high melting point, and superior conductivity. These qualities make them an ideal choice for modern motor vehicles, offering enhanced ignition performance, fuel efficiency, and longevity compared to traditional spark plug materials. Iridium spark plugs are designed to deliver consistent and reliable ignition, contributing to improved engine performance and reduced emissions in motor vehicles.

  • The elasticity and flexibility of silicone gaskets enable them to conform to irregular surfaces, creating a tight seal that prevents leaks and protects sensitive components
  • 7. Reconnect the battery Once the spark plug is installed and torqued, reconnect the negative battery cable to the battery.
  • Note! Seals with housing also require screws to be tightened according to factory guidelines.
  • The proper functioning of spark plugs is crucial for optimal engine performance.
