Draining Coolant in a Chevy Trailblazer
To drain the coolant in a Chevy Trailblazer, you have a few options based on the information from the search results:
1. Draining the Radiator:
– One method is to remove the lower radiator hose to drain the coolant from the radiator.
– Another option is to open the petcock on the radiator, although it’s mentioned that some models may not have this feature.
– It’s noted that there is no drain plug on the radiator after a certain year, so removing the lower hose seems to be the primary method.
2. Flushing the System:
– When flushing the system, it’s recommended to turn on the heat and blower motor to force the coolant through the heater core.
3. Draining the Block:
– There are discussions about draining the coolant from the engine block, with some users mentioning block drain plugs, while others indicate that there may not be drain plugs in the engine block for certain model years.
It’s important to consider the specific model year and any variations in the cooling system design when deciding on the best approach to drain the coolant from a Chevy Trailblazer.

How do you drain the coolant on a 2005 Trailblazer?
No, there is no block drain on this block. The factory recommended method to completely flush the system is to remove the radiator hoses (most of the coolant will drain from the lower). Then remove the thermostat (located just under the alternator, which is a little difficult to get to).
How can I drain my coolant tank?
To empty the system, let the engine cool, take the cap off the expansion tank, put the heater control inside the car on ‘hot’, and open the drain tap or remove the bottom hose. Open the bleed screws on the hoses and connections. They are usually thumbscrews and can be opened with the fingers.
What happens if you drain coolant?
Simply draining the radiator may get rid of most of the old antifreeze but could leave some coolant and contaminants behind, which would then mix with and pollute your new antifreeze and cause overheating. You want a full flush, a forced removal of anything old so you can pave the way for new fluid.
What is the easiest way to drain coolant?

One often overlooked aspect of car maintenance is the radiator flush. Regularly flushing your car’s radiator can help prevent damage to your engine and improve its performance.
How do you flush a radiator without a drain plug?

Do you need to flush coolant or just drain?
If you have something that’s over 10 years old and if you’re unsure about it, FLUSH IT. Contaminated/old coolant will start to carry rust/dirt particles through your engine and can cause a variety of bad things to occur, namely corrosion. For most people a drain and refill periodically is all you will ever need.
Do you have to remove thermostat to flush coolant?
No, it is not necessary to remove the thermostat. In fact, some cars you don’t want to remove the thermostat while running the vehicle. The reason for this is that the thermostat can be used to direct coolant flow. If it is out, parts of the engine may not be getting coolant as designed.
Where is the drain plug on a radiator?
