Iranian Firm Finds Solution for Bleeding Cylinder Head of Car

“Our company’s product is a bleeding kit that is designed to bleed cylinder heads of all cars but it is mostly used for cars like Samand, Peugeot Persia and 405 that have XU7 injection systems and produced inside Iran,” Payam Heydarnia, the managing director of the company stationed at the Islamic Azad University’s Hamedan branch, told ANA on the sidelines of Asr-e Omid event in the Northwestern city of Tabriz.

“Due to the use of gaskets, these cars need more bleeding, and this device prevents problems caused by heat in the cylinder head,” he added.

“Also our company's super-reinforced spark plug wire is made of copper wire with an alkali coating and has a noise-absorbing layer. Also, a silicone fireproof coating is placed, then a fireproof cotton coating, and finally another silicone layer. All materials used, like brass parts, are of high quality, and this product can be used for 20 types of vehicles,” Heydarian said.

Bleeding a car's cylinder heads (or more accurately, the cooling system) refers to the process of removing trapped air from the coolant system, which can lead to overheating and other problems. 

This is usually done by removing the radiator cap, refilling the coolant, and allowing the engine to run while monitoring for air bubbles.
