Unexpected explosion of coolant after new radiator install


Why did my coolant exploded?

In the event that you have excessive coolant pressure it will bypass the cap and overflow into the reservoir. If pressure ever got high enough to cause a failure, it would blow off or burst a hose, not crack the tank.

Why is coolant blowing out of my radiator cap?

1) Leaking Coolant



If the radiator cap is stuck, pressure may build inside of the radiator, which could cause cooling system components to leak or burst. If you notice coolant near the radiator or the radiator cap, then you clearly have leaky coolant.

Why is coolant shooting out of my reservoir?

Coolant, or antifreeze, is essential to regulating the temperature of your vehicle. It’s also extremely toxic and designed to stay inside a closed system. If you’re seeing an overflow, it could be due to a radiator cap, thermostat, water pump, or radiator malfunction.

What causes too much pressure in cooling system?

Leaks. The most common cause of radiator leaks is leaky hoses, but you can have leaks in the radiator itself, too, which can be a bigger problem. The coolant continually running from your radiator to your hot, running engine and back again creates a lot of pressure.

What are the three main causes of radiator failure?

An inspection of old radiators will reveal the main causes of radiator failure, such as corrosion, physical damage and electrolysis, and provide tips for visual inspection.

How do you know if your radiator burst?

Basically how you do it is take off the radiator cap. And then tilt the vehicle. So it's up on up on jack stands.

Why is my coolant reservoir boiling and overflowing?

Why Is My Coolant Reservoir Boiling And Overflowing? In fact, your vehicle could be overheating if the cooling system is bubbling and overflowing. Pressure on the cooling system prevent boiling but does not prevent further boilovers, simply causes an increase in temperature at that point.

How do I lower my radiator pressure?

There are several ways to release this pressure and we’ve ordered them by ease – however the techniques are not all available to every system.

  1. Open the filter valve. …
  2. Use a drain-off valve. …
  3. Bleed a radiator. …
  4. Undo a radiator nut.


Can be burst open by cooling system pressure?

If the radiator cap is stuck, pressure may build inside of the radiator, which could cause cooling system components to leak or burst. If you notice coolant near the radiator or the radiator cap, then you clearly have leaky coolant. Check to see if the radiator has holes in it or if the cap looks worn or damaged.

How do I know if my expansion vessel is faulty?

If you think the vessel has failed, unscrew the plastic cap from the pressurisation valve (it’s like a car tyre valve). Momentarily depress the pin in the valve to release a little pressure. If water comes out of the valve you have a definite expansion vessel fault.

Can a clogged radiator cause pressure?

A clogged radiator stops coolant from flowing into the water pump. With no coolant to lubricate its parts, metal will start grinding on metal, resulting in the building of pressure and the water pump getting damaged.

Can a leaking radiator cause a blown head gasket?

A head gasket failure may have been caused by an engine overheating one too many times (as a result of clogged radiator, coolant leak, faulty fan, etc.), but a blown head gasket will also cause the engine to overheat too.
