Built with full Tungsten Inert Gas welding and an O‑ring sealed cap, the unit is intended for universal fitment across a wide range of vehicles; measurement before purchase ensures proper clearance and fit. The bottom port serves as the radiator‑overflow connection while the top port vents excess fluid, and the package recommends Teflon tape on threads to improve airtightness at installation.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this reservoir integrate with my existing cooling system?\u003c\/h3\u003e\n\u003cp\u003eThe LokoCar tank functions as an overflow and recovery container that accepts excess coolant when system pressure rises, then returns fluid as the engine cools. It connects to your radiator via the bottom port and vents through the top port, using standard hose sizes and an M14 × 1.5 barb thread for a secure connection.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBottom port = radiator overflow inlet for returning coolant.\u003c\/li\u003e\n  \u003cli\u003eTop port = tank vent\/overflow outlet to atmosphere or catch line.\u003c\/li\u003e\n  \u003cli\u003eThread size M14 × 1.5 compatible with 3\/8\" ID hoses.\u003c\/li\u003e\n  \u003cli\u003eO‑ring sealed cap and TIG welding for leak resistance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this aluminum tank fit my vehicle and how do I check?\u003c\/h3\u003e\n\u003cp\u003eThe reservoir is sold as a universal item but requires a physical fitment check because mounting space varies by vehicle.

This LokoCar 1L aluminum expansion tank is aimed at car enthusiasts, DIY mechanics, and anyone replacing a cracked plastic overflow bottle or upgrading to metal for improved longevity. It's suitable for many passenger cars, light trucks and custom builds where a 1‑liter capacity and M14 × 1.5 barb fitment meet the vehicle's hose size and space constraints. If you prefer a compact, metal overflow solution with reliable welds and a sealed cap, this reservoir is a practical, serviceable upgrade—just measure first and plan hose adapters or mounting hardware as needed.\u003c\/p\u003e\n\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What hose size fits this reservoir?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The tank uses a male barb M14 × 1.5 designed to work with 3\/8\" ID hose; adapters can be used if needed.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the tank come with a warranty?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, LokoCar provides a 3‑month warranty; contact seller via Amazon message for support.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"LokoCar","offers":[{"title":"Default Title","offer_id":55168323846487,"sku":"B0CZ44R9VT","price":48.36,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/lokocar-reservoir-front-view.jpg?v=1790400044","url":"https:\/\/britishgarage.co.uk\/products\/lokocar-coolant-expansion-reservoir-tank-1l-aluminum-silver-tig-welded-m14-1-5-inlet-o-ring-cap","provider":"British Garage","version":"1.0","type":"link"}
