## Overview

Rislone Liquid Copper Block Seal is a cutting-edge, one-step cooling system additive that permanently repairs large leaks in radiators, intake manifolds, and more without draining your system. Its antifreeze-compatible sodium silicate formula ensures safe, fast, and effective sealing for all engine sizes, backed by a trusted brand with over a century of automotive innovation.

## Description

One Step, No Draining Required Antifreeze Compatible Sodium Silicate Formula Permanent Cooling System Repair Works with All Types of Antifreeze or Water Product Details: Older vehicles can develop leaks in their radiators and intake manifolds. If you’ve tried other stop leak products you know they are not powerful enough to stop larger leaks. That’s why Rislone designed this specific formulation. This one-step sealer was designed to quickly and safely stop these types of leaks. Our formula permanently repairs larger leaks in radiators, intake manifolds and gaskets, heater cores, blocks, heads and freeze plugs. It contains an antifreeze-compatible sodium silicate liquid glass formula, so no draining of the cooling system is required. It also will not harm the system when used properly. Other products can’t get your vehicle back on the road like Rislone — that’s why we’ve been the most trusted brand since 1921. Dosage: Use – 1/2 (half) bottle in a small cooling system, such as 4 cylinders with no A/C. Use 1 (one) bottle for regular size systems, which are for most 4, 6, 8 and 10 cylinder engines. Size: 510g

Review: Sosyal medyadaki yorum ve reklamlara kanarak fiyatı yüksek olmasına rağmen bu ürünü aldım hiç bir faydasını görmedim kimseye tavsiye etmiyorum reklamlarına kanmayın bu firmanın
Review: Produit défectueux contient des verres de terre. Ce produit a bouché le refroidisseur d'huile et il a fallu démonter la pièce mécanique. Facture du garage 500 euros. .. Je confirme cinq cents euros.
