Head Gasket Problems
What are bad head gasket symptoms?
It’s important to learn what head gasket failure symptoms look like to avoid higher expenses due to additional engine damage caused by driving with a blown head gasket. Some bad head gasket symptoms include:
- Coolant leaking externally from below the exhaust manifold
- White smoke from the exhaust pipe
- Bubbles in the radiator or coolant overflow tank
- Overheating engine
- White milky oil
- Fouled spark plugs
- Low cooling system integrity
Can I drive with a blown head gasket?
If you have multiple blown head gasket symptoms, it is important to drive your vehicle as little as possible. The hot gases and cold coolant moving through the hole in the gasket can quickly erode or warp the metal head or engine block. This can leave leaving you with costly machining bills or even the need having to purchase new heads or a new engine. Having water in your engine oil can destroy bearings quickly.

COOLING SYSTEM ISSUES
What is coolant?
The internal combustion uses heat to expand gases, which move the engine’s pistons (and your vehicle). Therefore, there will always be leftover heat after each cycle. This excess heat needs to be removed to keep your engine from overheating. The more quickly this excess heat can be removed, the more efficient the engine will be.
What should my coolant temperature be?
Different vehicles are designed to operate at different temperatures to protect the engine and its components as well as allow it to operate at maximum efficiency. The coolant temperature is controlled by two things: your vehicle’s thermostat and the engine’s cooling fans. Most engines are designed to run with coolant temperatures between 160 degrees and 200 degrees.
What is a head gasket coolant leak?
When you have a blown head gasket, it allows one or more of these fluids or gases to get to a place they shouldn’t be. A blown head gasket can allow combustion gases to get into your coolant or allow engine coolant to get into the combustion space or oil. It may also let engine oil get in all these places as well.

RADIATOR CLEANERS
How long can radiator flush be left in?
The BlueDevil Radiator Flush would not be acting as antifreeze, so it should be drained out and refilled with your regular antifreeze mixture. For extended cleaning, you can drive the vehicle for 3-6 hours with the flush in the system. Do not let the cooling system temperature fall below 32 degrees F.

RADIATOR LEAKS
Why is coolant overflowing from radiator?
If the overflow tank is too full coolant will spill out of that reservoir and may look like a leak. If this is the case, you should only see coolant overflowing the tank 1 or 2 times and after that, the excess coolant will be removed from the system and you shouldn’t see any more overflow.
How can I fix a leaking radiator heating core?
Fixing a leaking radiator heating core will always be much easier than replacing one. Since it is only a small leak in the heater core, we recommend simply sealing that leak and leaving your heater core in place. You can do this by simply adding BlueDevil Pour-N-Go to your vehicle’s radiator when your vehicle is cold. When BlueDevil Pour-N-Go reaches the leak point, the temperature differential will cause a chemical weld to form sealing your leak without affecting any other part of your cooling system.

CRACKED BLOCK
What are the signs of a cracked or blown head gasket?
An external head gasket leak causes coolant to come up from the intake or exhaust manifold and often happens when the engine is completely warmed up. Most head gasket leaks are internal and allow coolant to flow into the combustion chamber on every intake stroke. When this happens, coolant burns with the combustion process and appears as white smoke coming from the tailpipe. Some other signs of a blown head gasket are:
- Bubbles in the radiator or coolant overflow tank
- Overheating engine
- White milky oil
- Fouled spark plugs
- Low cooling system integrity
Is driving with a cracked engine block okay?
No! If you have multiple blown head gasket symptoms, it’s important to drive as little as possible!

AIR CONDITIONER REPAIR
Why is my car air conditioner blowing hot air?
The condenser in your air condition system looks a lot like a radiator and is mounted at the front of your vehicle. It is used to cool the hot compressed refrigerant back to ambient temperature as it comes from your compressor and uses the air your car is traveling through to do that. If not, the refrigerant will still be hot when it travels through the expansion valve. When that happens, the hot refrigerant will only be cooled back down to ambient temperature, so your AC won’t work. Since the condenser is at the front of your vehicle, it can get clogged by all kinds of road debris.
How to find a leak in car air conditioner?
The most common practice is to add a special dye to the air conditioning system. This dye is usually very difficult to see with the naked eye but will glow brightly when illuminated by an ultraviolet (UV) light. To discover where your refrigerant leak is coming from, add UV dye to your air conditioning system and enough refrigerant to ensure the compressor turns on. While the engine is running, have a friend turn on the air conditioning and blower. While he turns the AC on, watch the front of the compressor in your engine bay. The belt should always be spinning the AC compressor pulley, but right when the AC is turned on, the front of the compressor pulley should begin to turn as well. If you can see this happen, then you can ensure refrigerant, and your newly added dye is circulating through your air conditioning system.
Why is my car air conditioner fan not working?
Your car air conditioner fan not working is a common problem and a relatively easy fix without having to bring your car to the repair shop. If you are getting no air from the ventilation system in your car, you might not have a problem with your air conditioning system at all! If you’re getting air to blow but it’s not getting cold, that’s a different problem but hopefully still an easy fix.

- A Worn-Out Transmission
- Old/Wrong Transmission Fluid
- Low Fluid Levels
- Faulty Torque Converter
- Your Transmission Is Worn-Out
Worst case scenario, your transmission is worn out. The bands and clutches that cause gear changes wear down over time and as a result, their surfaces become smooth and no longer hold things together. Unfortunately, you’ll have to remove your transmission to test this. At that point, you might as well replace your transmission.
