Who should use Thermalweld?
B. A user has a big diesel engine, and the cost for a head gasket replacement could be as high as $7,000.
C. A user with an exotic vehicle such as a Jaguar, Aston Martin, Audi, Mercedes, or Porsche. The cost to replace a head gasket is off the charts.
D. A user that has tried an inferior head gasket repair solution and failed. Many times, Thermalweld has repaired a head gasket after a different product was tried and failed.

Overflow / Recovery Tanks.
- A radiator with a pressure cap
- 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.
A coolant system without a radiator cap has an expansion tank off to the side. Unlike the overflow/recovery tank, an expansion tank has a pressure cap. The pressure cap must be functioning properly or an overheating can occur. If an engine overheats damage to the head gasket is possible. Thermalweld provides an alternative to a complete teardown of the engine with a blown head gasket.
Take care of the radiator, avoid a blown headgasket.
Hot fluid enters the radiator from the upper radiator hose. The hot fluid goes down through the passages in the radiator. To cool the fluid as it passes from the top of the radiator to the bottom hose, the air is pushed through the front of the radiator while driving. Hot air is also pulled from the radiator with a fan in the engine compartment. If the radiator passages are clogged, fluid will not be cooled properly. The uncooled fluid will be recirculated back into the engine. Overheating will occur. Also, a water pump requires a steady flow of fluid to operate properly. If fluid cannot get to the water pump fast enough because of a clogged radiator, the water pump will cavitate. When a water pump cavitates, instead of steady flow through the engine block, short bursts of fluid will occur. If an engine is allowed to overheat the head gasket could be damaged. At the first signs of an overheating engine, pull over the vehicle immediately. Sometimes an engine overheats without the driver even knowing it. Sometimes a driver sees that the engine is overheating but keeps driving. The best advice is to stop the engine as soon as possible. Once an engine overheats, the need for a head gasket repair is probable.
How to avoid a blown head gasket.
If the coolant enters the crankcase it will mix with the engine oil. Agitation caused by the crankshaft, rods and other moving parts can spin the coolant and oil like a blender. The results look like mocha coffee. To check for coolant in the oil remove the oil fill cap on the engine. If it looks like mocha coffee, coolant is in the oil. The need for a head gasket repair is probable. When coolant is forced out of the exhaust system it is heated by the exhaust manifold and the rest of the exhaust system. The results are sweet-smelling steam coming from the tailpipe. When coolant hits the hot exhaust system it is like water on a hot iron. Once again, a head gasket repair is probably needed. To avoid a head gasket repair, never let the engine overheat. Check the coolant level, and have the coolant exchanged at proper intervals
Trapped air in the cooling system.
- Park the vehicle (on an incline if possible). Let the engine cool down. Now you are ready to remove the air in the cooling system.
- Open the hood. Some newer cars have a bleeder valve on the front of the radiator, or on the thermostat housing. Check the owner’s manual for the location of this valve, and how to use the ‘bleeder valve” to remove the air from the coolant system.
- After the engine cools down. Remove the radiator cap. If the level of the radiator fluid went down, that indicates the air has been bled out of the cooling system. Top off the radiator, turn on the car, let it run. Continue to add more fluid if needed.
If there is no bleeder valve on your coolant system. With the engine cool, remove the pressure cap off of the radiator or expansion tank. Top off with fluid. Run the engine until it comes to operating temperature. The air will rise out of the radiator, and the fluid level will go down. Use caution, the fluid in the system will be hot. If the fluid begins to flow out of the radiator or expansion tank, let the engine cool down. Be careful because the fluid will be hot. Always wear personal protective gear like leather gloves and safety goggles. After the engine cools, top off the system. The air should be eliminated. Repeat the process if necessary. Check fluid level periodically. To avoid the need for a head gasket repair, periodically exchange the antifreeze in the coolant system as recommended.
