How do you mix Radicool concentrate?

Table of Contents

This coolant can be mixed using 33% concentration with purified water to give frost protection to -18 deg C, however it is recommended to use a 50% dilution to provide optimum corrosion protection and freeze protection down to -36 deg C.

How do you use Castrol Radicool concentrate?

If using Castrol Radicool for the first time, ensure that the cooling system has been adequately flushed with clean water before use. When top up of the cooling system is necessary, add only Castrol Radicool concentrate mixed with demineralised water at the recommended concentration.

How to use Radicool?

Castrol Radicool SF should be diluted between 33% and 50% concentration, with deionised/distilled water. For best all round performance, it is recommended that a 50% mixture in water is used. Concentrations higher than 70% volume are not recommended.

Do I mix concentrate coolant with water?

Most manufacturers recommend a 50/50 mix of antifreeze concentrate to water. Mixtures with too much water may not provide adequate boil over or freeze protection. Mixtures with too much antifreeze concentrate may actually cause over heating.

What is SI oat?

Description. Oat Si Antifreeze is an ethylene glycol based engine coolant concentrate, which uses Organic Acid Inhibitor Technology in combination with silicate and is free from nitrites, amines, phosphates, borates.

What does Radicool mean?

radicool (comparative more radicool, superlative most radicool) (slang) Cool, awesome.

Is Castrol Radicool SF a premix?

Castrol Radicool SF-O Premix, a heavy-duty, nitrite-free, extended-life antifreeze/coolant, is a premium quality, Organic Acid Technology (OAT), ethylene glycol-based fluid.

Is it OK to put concentrated coolant?

ANSWER: There are three reasons why pure antifreeze (ethylene glycol) shouldn’t be used at full concentration in a car’s cooling system. The first and perhaps most important reason is that pure ethylene glycol freezes between 0 degrees and minus-5 degrees F.

How much water do you add to concentrated coolant?

Mixtures with a ratio of 50:50 work almost in every climate. In climates where temperatures drop below 0℃ for a longer period, mixtures closer to 60% antifreeze and 40% water are better suited to keep coolant from freezing.

Does concentrated antifreeze need to be diluted?

Whether you’ve done a cooling system flush or you’re tapping off the level, it should be a mix. The ONLY exception to this is if you’re adding, and what’s already in the system is pure antifreeze, then you’ll want to dilute it as close to 50/50 as possible with only distilled water (or vise versa).
