Guide to Adding K-Seal (General Installation)

 If this is a vehicle you have recently purchased or are unsure of the maintenance history then it is advisable to perform

a cooling system flush procedure before adding K-Seal.

 Make sure you shake the bottle thoroughly (at least 30 seconds) to ensure the contents are well mixed. Check the

bottle after adding and if necessary add more water and shake again to ensure all contents are added to the system.

 When adding via the overflow / expansion tank, add K-Seal first and then top up the coolant. This helps to get K-Seal

into the cooling system more quickly.

 It is fine to add K-Seal to a cold cooling system, just let the engine idle up to normal operating temperature. K-Seal can

also be added to a hot system but use caution as the system will be under pressure and hot coolant can scald you.

 For heater core repairs, set the heater controls in the ON/HOT position and confirm that hot air is blowing before

adding K-Seal. If there is no heat in the cabin, there is most likely an air-lock that will hinder K-Seal from circulating.

The heater matrix is often the highest point of the cooling system, and any air in the system will gravitate there

potentially impeding the flow of coolant. If there is no heat after adding K-Seal bleed the cooling system to remove any

air locks.

 Once K-Seal has been added allow the vehicle to idle for about 20 - 30. Higher revs or driving the vehicle will increase

pressures in the cooling system which can sometimes make a repair more difficult, in particular with head gasket issues

(see additional instructions on following sheet).

 You may also wish to leave the cap off the expansion tank or radiator while idling to vent any air-locks and additionally

prevent any vacuum developing as a result of from coolant still leaking.

 Occasionally with minor leaks it may take multiple heat / cool cycles for K-Seal to be able to make a repair. Just use the

vehicle as you would for up to ten days after and if K-Seal has not made a repair then it is unfortunately unlikely to do

so.

 To help identify which particular part of the cooling system that might be leaking it is well worth having a look at our

interactive diagram here: ENGINE COOLING SYSTEM INTERACTIVE DIAGRAM

 For motorcycles or other small cooling systems with only a couple of quarts / litres capacity, simply add a quarter to

half of a regular bottle but make sure the contents are very well shaken first. If the leak remains then add the

remainder of the contents.

If you add K-Seal directly to the radiator, ensure there is enough

coolant to cover the core which (shelf at the top) to ensure that

K-Seal is added to fluid rather than hitting the core first. One

option is to pre-mix K-Seal in a larger container of water and then

add to the radiator. This will assist dispersal of the K-Seal

throughout the cooling system.

Foaming is a rare side effect of adding K-Seal which will not

interfere with the repair process. It sometimes occurs with head

gasket issues.

If you notice foaming, just idle the engine with the expansion or

radiator cap off to let the foam escape. Once a repair is made you

can drain and flush the system to remove and residual foam.

K-Seal Installation Guide for Severe Over-Pressurising Systems (Head Gasket) In certain instances of Head Gasket Failure K-Seal is prevented from repairing due to combustion gases entering the cooling system causing over pressurisation. Two tell-tale signs to look out for are: 1. Coolant being expelled from the expansion or overflow tank while the engine is left idling.
