Coolant Reservoir Products

Overheating would be a regular thing if cars weren't equipped with a cooling system. That said, overheating isn't only inconvenient; but more importantly, it's also harmful to the engine assembly. So to prevent it from happening, the cooling system must be kept in tiptop shape. For that, you'll need a coolant reservoir. Also known as an expansion tank or recovery tank, this reservoir stores coolant for future use. Without it, coolant would drip uselessly to the ground, making your engine at risk of overheating. Also, you'd be spending even more money buying coolant just to keep your engine at a stable temperature. But with a reservoir, once the engine temperature becomes stable, the coolant stored in the reservoir flows back to the radiator. This way, you wouldn't have to keep on refilling your radiator with expensive coolant. Yet aside from serving as storage for the coolant, this reservoir also helps in removing air bubbles from the system. So, the coolant is able to soak up heat more efficiently. On top of that, you wouldn't have to worry about rust forming from oxygenation. In case the reservoir gets damaged, though, you must find a replacement immediately. Finding a high-quality replacement is easy since the market is filled with a wide selection from trusted auto parts manufacturers. But if you want to avail of a superior yet affordable coolant reservoir, shop at Auto Parts Warehouse. We offer reliable ordering service and fast product delivery to all our customers.

Choosing the Right Coolant Reservoir

Your engine cooling system keeps everything under the hood of your car from overheating. One important part of this cooling system is the coolant reservoir. It holds the very element that cools your entire engine--the coolant. So when your car starts overheating and you find a leak underneath it, it's about time you go shopping for a new coolant reservoir. Choosing the right one can get a little tricky because of all the available options. So be sure you've got every coolant reservoir question answered before you decide on one.

Plastic vs. aluminum vs. stainless steel coolant reservoirs

To get the most out of your coolant reservoir, you have to make sure that it is made from the toughest material available in the market. But what is the best material for a coolant reservoir? There are basically 3 types of reservoir according to material-plastic, aluminum, and stainless steel.

If you're talking about durability and resilience, it is a choice between getting either an aluminum or stainless steel reservoir. Both are highly resistant to corrosion and are more visually appealing. The important difference between aluminum and steel, besides the price, is their weight. Aluminum is relatively lighter than steel. So if you want a faster and leaner car, a more aerodynamic aluminum coolant reservoir is your best bet. However if you're strapped on cash and you just need a cheap replacement for your already leaking coolant reservoir, you can buy one made out of plastic. It is a more practical and cost effective alternative to both aluminum and steel. But be wary when choosing plastic. It tends to develop minute and almost invisible cracks over time.

Buying an individual coolant reservoir or choosing one sold in a kit

Topnotch engine cooling starts with perfectly fitted parts, so it's only natural to consider whether you should buy a coolant reservoir individually or in a kit. The answer to this question will largely depend on its material. If you decide to go for plastic, you'll hardly find one that is sold in a kit. Plastic coolant reservoirs are already made with fasteners that attach them to your system, which eliminates the use of gaskets and O-rings. But if you have your eyes set on either an aluminum or stainless steel coolant reservoir, it is best to purchase one in a kit. This will ensure that all mounting brackets, hoses, hardware, and other connecting parts are of the right shape and size.

OE replacement parts vs. aftermarket products

Some might experience difficulty when looking for replacement coolant reservoirs from secondary sources. There is no generic, one-size-fits-all part when it comes to coolant reservoirs. Most aftermarket products have limited variety and might not fit the rest of your engine cooling system. So just to be on the safer side, make sure you get an OE replacement part. This will save you the hassle of going through tons of dealers just to find one that will ensure a perfect fit.

How to Replace Your Coolant Reservoir

Coolant, also called as antifreeze, serves a dual purpose in keeping your engine running properly. This solution cools and lubricates the metal parts to prevent overheating under extreme heat. During winter months, it acts as the antifreeze that prevents the engine from locking up with ice and becoming frozen. This essential fluid is stored in a container called the coolant reservoir. Once this storage tank leaks or cracks, the engine might suffer from loss of lubrication, overheating, and metal corrosion. Immediately replace a damaged coolant reservoir to prevent engine malfunction. Here are the tools you'll need and the steps in replacing your old coolant reservoir:

Difficulty level: Moderate

Tools that you need:

  • Drain pan
  • Wrenches
  • Radiator hose
  • New coolant reservoir
  • Rags

Step 1: Allow your engine to cool down for at least an hour prior to doing the replacement. This will allow the coolant to drain back into the engine so that you won't have to dispose a large amount of it. Disconnect the battery for safety purposes.

Step 2: Remove the bolts keeping the coolant reservoir in place but do not remove the coolant hose. Detach the reservoir from the vehicle body. Wrap a rag around the hose first before disconnecting it from the reservoir. Allow the remaining coolant to flow back into the drain pan.

Step 3: Take out the damaged reservoir and drain it of old coolant. Pour the fluid into an air-tight container and screw the top back on tightly. Do not allow the coolant to leak out, as it is highly toxic. Dispose of the container properly.

Step 4: Attach the coolant hose to your radiator and tighten the clamp firmly. Connect the other end of the hose to your new coolant reservoir. Secure it into place using a set of mounting bolts. Tighten all bolts to ensure there are no leaks. Fill the tank with new coolant and run your engine for testing.
