How to Remove an Old Radiator

One of the great deterrents to anyone wanting to remove a radiator is the prospect of having to drain the whole system. However, this won’t be necessary provided the radiator to be replaced has a valve at both the hot water inlet and the outlet. Once these are closed, you’ll be able to keep virtually all the system’s water isolated in other parts.

At the inlet end you’re likely to find the hand-valve which is the control by which you open and close the radiator. At the outlet end you’ll find what is termed the lock-shield valve. When you come to inspect your radiator, don’t worry if their positions are reversed – they will still be equally effective.

The first thing to do when removing a radiator is to close these valves. The hand-valve is straightforward, but you’ll have to remove the cover to get at the lock-shield valve. You’ll be able to close this valve using a spanner or an adjustable wrench with which to grip its spindle.

As you turn it, it’s a good idea to note carefully how many turns it takes to close. And you’ll find this task slightly easier if you mark the turning nut with a piece of chalk before you begin. The reason for all this is to maintain the balance of the system. After it was first installed, your system would have been balanced. The lock-shield valves of all the radiators were adjusted to give an equal level of water through-flow so that they were all heating up equally. So, by noting the number of turns taken to close the lock-shield, when you come to fit the new radiator you can simply open it up by the same amount -so avoiding the somewhat tedious task of rebalancing the whole system.

Once you’ve closed both valves, you can unscrew the nuts which connect the valves to the radiator inlet and outlet. Do these one at a time after having placed a low dish under each end to collect the water and protect the floor Use an adjustable wrench to undo the coupling nuts. It’s wise to hold the circulating pipe securely in place with another wrench. Otherwise, if you apply too much pressure to the coupling nut you risk fracturing the flowpipe, and this would cause you a lot of extra work and expense to mend – as well as causing quite a mess. As you unscrew each nut, the water from the radiator will flow out. If the system has been previously treated with corrosion proofer, it’s well worth saving the water. That way you can pour it back into the feed-and-expansion tank when the job is complete.

Once the water has drained out, remove the tail pieces and coupling nuts from each end. Then block up each hole with a rag and lift the radiator from the brackets that hold it to the wall. It’s a good idea to get the radiator out of your home as soon as possible – just in case it leaks any remaining dirty water on to your carpet.

Removing the old radiator

1 Turn off the flow control valve by hand, and the lock-shield valve by turning its spindle with pliers. Note how many turns are needed to close it completely.

2 Hold the lock-shield valve body with a wrench so you don’t bend the pipework, and undo the valve coupling carefully with an adjustable spanner.

3 Open the air-bleed valve, pull the coupling away and allow the radiator to drain into a convenient container. Have rags and a larger bowl handy too.

4 Having drained most of the water, undo the other coupling, lift the radiator off its brackets and drain out the dregs. Then remove the old brackets.

How to Stop Radiator Leaks

When you notice that there is leakage in your radiator, then it requires fixing. Leaks can result to overheating when the vehicle cooling system fails. This will lead to an ineffective engine cooling. Sometimes leakage is the most common form of problems in the engine’s cooling. The radiator leaks can be prevented with proper maintenance. Fixing your radiator before it worsens is always the best way to keep your car in good shape.

Radiators are devices that help transfer heat in vehicles. The heat exchanges brought about by radiators is present in automobiles, electronics, and buildings. They are designed to transfer heat by thermal radiation to arrive to a cooling or heating effect.

You will need duct tape and ground black pepper to learn how to stop radiator leaks.

Radiator Leaks How to Stop Radiator Leaks

These are the steps to be followed:

Step 1: Find the location of the leak in your radiator. If the leak comes off a hose, patch the leak with the duct tape. The duct tape can only stay on the surface for about a week. Then you will need to replace the hose.

Step 2: If you find the leak in the radiator, remove the cap and add 1 or 2 teaspoons of ground black pepper in it. Pepper lodges into the holes and also swells when submerged in water and will mount to seal the hole.

Step 3: Close the radiator cap once it is filled with the water up to the proper water level.

Step 4: Bring the pepper with you and a jug of water as it may be required fry u to add more water or pepper into the radiator.

Step 5: The last step is important. Schedule a meeting with the mechanic. Let him know the temporary measures you have taken.

Tip: There are best leak stoppers used by mechanics and automobile owners alike. Some of these leak stoppers are Silver Seal Heavy-Duty radiator. This stops leaks and inhibits the rust. It also lubricates the complete cooling system. The good advantage of the leak stopper is that it combines well with any anticoolant.

Warning: Always keep some extra water with you when you are going for a drive. This will help you quickly fix a leak if it happens. You also have to make use of 3 to 4 white eggs to prevent leakage from the radiator. The eggs works in the same way as the paper does.
