The Toyota Supra MKIII is a legendary sports car that has captivated automotive enthusiasts for decades. Unfortunately, however, it is very susceptible to head gasket problems. Fortunately, a simple solution can help you avoid this costly and time-consuming repair. In this article, we will explore the causes of head gasket failure in MKIII Supra and provide an effective solution to save your beloved car from this situation.
What is head gasket failure?
The head gasket plays a critical role in the proper operation of the engine by sealing the combustion chambers and preventing coolant and oil from mixing. However, the head gasket can deteriorate over time due to various factors. Problems such as engine overheating, insufficient maintenance or wear and tear will create a point of failure. When a head gasket fails, it can have serious consequences, including loss of power, overheating, coolant leaks, and possible engine damage.
MKIII Toyota Supra Head gasket problems
The Toyota Supra MKIII, especially the 7M-GTE engine variant, is extremely susceptible to head gasket failure. This problem arises mainly due to the design of the factory head bolts and the aluminum construction of the engine. The head bolts are initially torqued incorrectly from the factory. However, if the head bolts have not been stretched, you can re-adjust them to the proper setting to save yourself some money.
However, the combination of high-performance driving, increased cylinder pressure, and engine aging can cause the head bolts to stretch and lose their holding power. This results in a compromised seal between the head gasket and the engine block. A telltale sign of a failed head gasket is engine overheating and coolant leaking out the side of the block.
Solve head gasket problems with an ARP head stud kit
Fortunately, there is a simple but very effective solution to prevent head gasket failure on the MKIII Toyota Supra. Installing an ARP (Auto Racing Products) head stud kit can significantly improve the clamping force and overall strength of the head gasket assembly. The ARP Head Bolt Kit replaces the factory head bolts with high-quality studs, washers and nuts that provide superior clamping force, ensuring a secure and reliable seal. The ARP Head Stud Kit offers several benefits:
Increased Clamping Strength: ARP studs will withstand higher stress levels than factory head bolts. This helps prevent the head gasket from losing its seal under extreme conditions.
Enhanced Durability: MKIII Toyota Supra studs contain premium materials such as ARP2000 or Custom Age 625+. The materials ensure exceptional strength and resistance to stretching or fatigue.
Easy Installation: Each ARP head stud kit is vehicle specific, making the installation process simple. However, professional installation is always ideal for best results.
Cost-Effective Solution: An ARP Head Stud Kit may seem like an extra expense. However, it is a small price to pay compared to the potentially catastrophic consequences of head gasket failure. You can save yourself from costly engine repairs by proactively avoiding this problem.
Should you replace the head studs?
The Toyota Supra MKIII is an iconic sports car that deserves to be preserved and enjoyed for years to come. By addressing the common problem of head gasket failure by installing an ARP head stud kit, you can ensure the longevity and reliability of your beloved vehicle. With increased clamping force and improved durability, this simple solution effectively prevents costly engine damage. A small price to pay to keep your MKIII Supra running smoothly on the road or track. So don’t wait for a head gasket failure to happen; take proactive steps to safeguard your Supra’s performance.
