There is wisdom in paying attention to your engine temperature gauge and stopping any signs of overheating in its tracks. After all, an overheated engine can suffer damage like warped cylinder head, which in turn may lead to other problems, like a blown head gasket
How would one display the necessary caution when attempting contemporary radiator repairs in Ashland?
The thing is that modern radiators typically have a separate overflow reservoir indicating the proper coolant level. On some vehicles, the coolant can be checked via the radiator cap once the engine is cold enough. Some manufacturers may use a sealed system with no accessible radiator cap.
Take care never to loosen the radiator cap when the engine is hot – scalding coolant will spray out.
To check the coolant level in the radiator once the engine is cool, press down on the radiator cap and ensure you rotate it counterclockwise two positions before removing it.
You should be able to notice the coolant through the open filler neck. If you’ve just replaced the radiator or a hose or have flushed the radiator, you will need to fill it here.
If you are refilling an empty cooling system, mix equal parts coolant and water using a clean container then pour from that.
An inexpensive tool some Ashland Radiator repair specialists use to fill radiators features a reservoir that attaches like a radiator cap at the filler neck. You should pour coolant until it fills the bottom of the reservoir and run the engine with the tool attached. Add coolant if the reservoir empties. When no more coolant flows into the radiator, insert a plunger style plug to seal the reservoir, then remove the tool and install the radiator cap.
Your radiator has an overflow reservoir. If the pressure reaches too high in the radiator, the cap will release pressure and expel some coolant into the reservoir. As the system cools down and pressure drops, it will draw some coolant back into the radiator.
The overflow container should always have some coolant in it. A marker will indicate where the level should be when the system is cold or hot. If the reservoir is low, add coolant until the level is just above the COLD fill line.
Note: Your cooling system is filled with the antifreeze concentration the manufacturer recommends, usually a 50/50 coolant and water mix.
Some coolants come premixed, so you need to read the label. Use a funnel and pour slowly to avoid a spill. If you’ve drained the cooling system, it will contain air that must be displaced with coolant. To do so, grab and squeeze a radiator hose a couple of times as you fill.
Be patient, you will need to add coolant slowly to allow air to escape and the system to fill completely.
You Should Check the Fluid Concentration
When your radiator is cold, take care to remove the radiator cap. Squeeze the rubber bulb on the antifreeze tester. Insert the tube into the radiator filler neck and release the bulb.
Draw coolant out until it fills the plastic reservoir and read the indicator. It will show the freezing point of your coolant mixture. This point must be below the lowest temperatures experienced in your area. If the strength is too weak, add pure antifreeze coolant; if it is too strong, add distilled water, then retest.
How Would You Go About Changing the Radiator Cap and Thermostat?
Radiator caps are spring loaded to maintain a certain amount of pressure in the system. When cooling system pressure is too high, the spring loaded seal is forced upward, releasing pressure and allowing coolant to escape into the overflow reservoir. It is not a bad idea to replace your radiator cap every few years, or according to manufacturer recommendations, to be sure it seats and functions properly. To remove with the engine cold, push firmly down with the palm of your gloved hand and twist the cap counterclockwise.
On most vehicles, the thermostat is located where the top radiator hose connects to its housing. Removing the thermostat housing will typically release some coolant, so position a drain pan accordingly. Better yet, drain the radiator down to a level below the thermostat housing.
Be sure you use the correct socket or open-end wrench to reach and loosen the thermostat housing bolts.
When you remove the housing, you need to note where it is positioned on the engine.
Once you are done replacing the thermostat, you need to run the engine and check for leaks.
