Before you do this, use extreme caution whenever you’re working on a hot cooling system since hot coolant and gases could cause injury. In case you can’t, please consult a qualified mechanic.

1. First, shake the bottle very well and pour the entire contents into the radiator

Note that K-Seal products are compatible with various kinds of antifreeze/coolant and cannot be affected by any other additives already in your cooling system.

Also, you can add K-Seal products to a cold or hot engine, however, you must be careful when working with a hot engine.

engine idling till the temperature gauge reaches its normal level.

3. You can either change the cooling system contents or leave the K-Seal in the system

But the Size Matters

Indeed, the cooling systems in some vehicles come in different sizes, and unsurprisingly, they sometimes need to cater for different-sized engines. As you know, it is obvious for an eighteen-wheeler truck to run a bigger engine than a Mini Cooper. This means that the cooling system needs to be large enough to cool an engine of such size.

So the K-Seal provides the original multi-purpose K-Seal in two various sizes making sure that customers do not buy either a bottle that’s too small for their vehicle or buying a bottle that’s too big.
The K-Seal is best used in vans, cars, mini trucks and motorbikes that has cooling systems of up to 20 liters/21 quarts
The K-Seal HD (Heavy Duty) happens to be the best for larger trucks, heavy plant, tractors, and other heavy duty engines that has cooling systems of up to 57 liters/60 quarts

However, in case you have any doubts about whether you need K-Seal or K-Seal HD in your vehicle, make sure to consult your mechanic who will be happy to help you with the right option.
