Automotive coolant overflow solution designed to replace brittle plastic reservoirs and manage coolant overflow reliably. Adds confidence for DIY mechanics and tuners who want a neater, more serviceable engine bay. Will the VVORHSBELL Coolant Expansion Tank fit common engine bays and resist leaks over time?
⚡ At a Glance
- • Build Quality: 7075 aerospace-grade aluminium construction, fully TIG welded, tight-closed cap with O-ring gasket
- • Best for: DIY mechanics and performance tuners seeking a durable, serviceable overflow reservoir
- • Not ideal for: Vehicles with very limited engine bay space or where an exact OEM-fit replacement is required
Universal 1 litre aluminium radiator overflow reservoir with switchable ports and sight tube. Captures coolant when radiator pressure exceeds the cap setting and keeps the coolant sealed.
Leak-resistant overflow control - thanks to TIG-welded construction and O-ring gasket
Fully TIG-welded seams and a tight-closed cap fitted with an O-ring create a sealed reservoir. Pressure from the radiator passes through the overflow tube into the tank when radiator pressure exceeds the cap setting.
Sealed construction reduces the chance of coolant loss and contamination. Sight tube level indicator makes leak detection and monitoring straightforward.
Flexible installation and easy servicing - with switchable inlet/outlet and magnetic drain plug
Switchable inlet and outlet ports allow the sight tube and fittings to be positioned left or right to suit engine bay layout. A magnetic drain plug at the bottom enables fast draining and cleaning without full removal.
Adaptable port placement suits a wide range of vehicle layouts and simplifies plumbing. Bottom drain speeds routine maintenance and reduces mess.
High-temperature durability - with 7075 aerospace-grade aluminium
7075 aluminium delivers higher strength and heat resistance than common plastic reservoirs, maintaining structural integrity under elevated under-bonnet temperatures. Threads and welds are finished to create a tight, durable seal.
Less prone to cracking or warping near hot components, extending service life. Robust material supports repeat maintenance and performance upgrades.

❓ Frequently Asked Questions
Q: Will this fit my car?
A: Compatibility is universal with many popular marques including Honda, Toyota, Ford, BMW, Vauxhall, Mercedes and Nissan, but confirm available engine bay space before purchase.
Q: Is the reservoir leak-proof?
A: TIG-welded seams plus a tight-closed cap with an O-ring gasket are designed to maintain a sealed environment; using Teflon tape on threaded fittings is recommended to enhance airtightness and prevent interface leakage.
Q: How do I drain and check the coolant level?
A: A magnetic drain plug at the bottom allows easy draining and cleaning, while a toggle sight tube gives a clear, readable coolant level indicator.
🏆 Our Verdict
Suitable for DIY mechanics, tuners and anyone replacing brittle plastic overflow bottles with a more serviceable option. Durable 7075 aluminium construction, TIG-welded seams, switchable ports and a magnetic drain plug give practical advantages in installation and maintenance. Built for long-term value through stronger materials and easier servicing rather than one-off convenience.
