Why Upgrade Your Mustang’s Coolant Tank? The Moroso Advantage
Many Mustang owners eventually face issues with their factory coolant expansion tanks. These plastic components are notorious for becoming brittle, discolored, and eventually cracking due to heat cycles and age. A failing tank can lead to coolant leaks, air in the system, and ultimately, engine overheating.
Common OEM Coolant Tank Problems
Over time, the plastic used in original equipment manufacturer (OEM) coolant tanks degrades. This degradation can manifest as hairline cracks, especially around hose connections or mounting points. Discoloration, often a yellowish-brown hue, is another tell-tale sign of aging plastic.
These issues are more than just cosmetic. A compromised tank can’t hold proper system pressure, leading to reduced cooling efficiency and potential engine damage. It’s a ticking time bomb for your Mustang’s cooling system.
The Benefits of an Aluminum Moroso Coolant Tank
A Moroso Mustang coolant tank, typically crafted from high-quality aluminum, solves these problems definitively. Aluminum offers superior durability and resistance to heat and pressure compared to plastic. It won’t crack, discolor, or become brittle.

Installing Your New Moroso Mustang Coolant Tank: A Step-by-Step Guide
Replacing your coolant tank is a manageable DIY project, but it requires careful attention to detail and safety. Always work on a cool engine and take precautions against hot coolant.
Tools and Materials You’ll Need
Before you begin, gather everything you’ll require:
- New Moroso Mustang coolant tank
- Fresh engine coolant (ensure it’s compatible with your Mustang’s system, typically a 50/50 mix of distilled water and concentrated coolant)
- Coolant drain pan or large bucket
- Socket wrench set (typically 10mm, 13mm, 15mm)
- Pliers (for hose clamps)
- Screwdriver set (flathead for prying, if needed)
- Funnel
- Clean rags or shop towels
- Safety glasses and gloves
- Torque wrench (optional, for specific fasteners)
Safety First: Essential Precautions
Working with a cooling system involves hot fluids and potentially pressurized components.
1. Allow Engine to Cool: Never open the cooling system when the engine is hot. Wait until it’s completely cool to the touch.
2. Eye and Hand Protection: Always wear safety glasses and gloves to protect against coolant splashes.
3. Proper Disposal: Collect all drained coolant in a pan. Coolant is toxic; dispose of it responsibly at an authorized recycling center. Do not pour it down drains or onto the ground.
Step-by-Step Installation Process
Follow these steps carefully for a smooth installation:
1. Drain the Coolant
Place your drain pan beneath the radiator drain plug or the lowest hose connection. Slowly open the radiator drain plug (if accessible) or carefully remove the lower radiator hose to drain the coolant. Collect all fluid.
2. Disconnect Hoses and Sensors
Locate your existing coolant expansion tank. Use pliers to squeeze and slide back the hose clamps, then gently twist and pull the hoses free from the tank. There will typically be a large main hose, a smaller overflow hose, and potentially a sensor wire. Disconnect the sensor wire if present.
3. Remove the Old Tank
Unbolt the existing tank from its mounting points. These are usually 10mm or 13mm bolts. Once unbolted, carefully lift the old tank out of the engine bay.
4. Transfer Components (If Necessary)
Some Moroso tanks require you to transfer the factory coolant level sensor or cap. Follow the instructions provided with your new tank. Ensure any rubber grommets or O-rings are in good condition for a tight seal.
5. Install the New Moroso Tank
Position the new aluminum tank into the engine bay, aligning it with the factory mounting points. Bolt it securely into place using the factory hardware or new hardware supplied with the tank. Do not overtighten.
6. Reconnect Hoses and Sensors
Reconnect all hoses to the new tank, ensuring they are fully seated. Slide the hose clamps back into their original positions over the hose and tank connections. Reconnect any sensor wires. Double-check all connections for tightness.
7. Refill the Cooling System
Using a funnel, slowly add the fresh 50/50 coolant mix to the new tank. Fill it to the “COLD” or “MIN” line.
8. Bleed the System and Check for Leaks
Start the engine with the coolant cap off. Turn your heater to full hot (this helps open the heater core valve). Allow the engine to warm up to operating temperature. As it warms, air bubbles will rise and escape through the open tank. You may need to gently squeeze the radiator hoses to help trapped air escape.
As the coolant level drops, continue to top it off. Once the engine is at temperature and no more bubbles are escaping, replace the coolant cap. Take the car for a short drive, then allow it to cool completely. Check the coolant level again when cold and top off as needed. Inspect all hose connections for any signs of leaks.
Maintenance and Troubleshooting Your Upgraded Cooling System
Even with a robust Moroso Mustang coolant tank, regular maintenance is key. Knowing how to spot and address common issues will keep your cooling system performing optimally.
Routine Checks for Longevity
- Coolant Level: Regularly check your coolant level when the engine is cold. It should be between the “MIN” and “MAX” lines.
- Hose Inspection: Periodically inspect all coolant hoses for cracks, bulges, or signs of wear. Replace any damaged hoses promptly.
- Cap Condition: The coolant pressure cap is a critical component. Ensure its rubber seals are intact and that it holds pressure correctly. Replace it if it shows signs of age or damage.
- Cleanliness: Keep the exterior of your aluminum tank clean. While less prone to staining than plastic, a clean surface makes it easier to spot potential issues.
Common Issues and How to Address Them
Even with a new tank, problems can arise. Here’s how to troubleshoot:
- Coolant Loss After Installation: This often indicates an air pocket in the system that’s bleeding out, or a loose hose clamp. Re-bleed the system thoroughly and check all clamps.
- Overheating: If your Mustang overheats after installation, it’s usually due to air trapped in the system or an unrelated issue like a failing thermostat or water pump. Re-bleed the system first. If problems persist, consult a professional mechanic.
- Leaks Around Connections: Double-check that all hose clamps are tight and properly positioned. Ensure the hoses are fully seated on the tank’s nipples. If the leak persists, the hose itself might be old and need replacement.
- Low Coolant Light: If your Mustang has a coolant level sensor and the light comes on, first check the actual coolant level. If it’s full, the sensor itself might be faulty, or there’s still air causing it to read incorrectly.
