Generally, there are two types of coolant systems:
1. A radiator with a pressure cap
2. A radiator without a pressure cap.
A coolant system with a radiator cap has an overflow / recovery tank. It is a common component found in most automotive applications. They are typically connected by a tube to the radiator neck, and it serves as a place for excess fluid to be captured when the pressure release valve in the radiator cap gives way. When the engine cools down the pressure normalizes within the coolant system, and the fluid is pulled back into the radiator. If the radiator cap is defective overheating can occur resulting in a blown head gasket. If the tube is blocked a head gasket can be damaged. Ideal Head Gasket Repair has been in business since 2011. Over 700 successful head gasket repairs.
Some older vehicles did not have overflow tanks at all. The fluid expansion would occur in the radiator itself. It was common to leave an inch or more of air at the top of the radiator tank. When the coolant system was pressured, the air would vent through the radiator cap. The problem with a coolant system with no overflow tank is, the fluid level could become too low, causing an overheating issue. One overheating incidence can cause the head gasket to blow. Call Ideal Services to get your head gasket repaired.
