How to use the SLICTank patch kit to repair your SLICTank
1) The key to a good repair is to properly identify the source of the leak so that you can focus your repair on this area. Remember your coolant can travel quite far on the bottom of the SLICtank, and so it's particularly important to clean off all the coolant and then periodically check it with your finger to find the leak. Since the Coolant is clear it can be difficult to locate the true source of the leak.
2) To inspect the tank and identify the area that appears to be leaking, we recommend cleaning the areas under the tank where you can feel fluid on the surface. You can clean the areas where you are seeing or feeling any droplets forming with Simple Green or 409 or similar degreaser.
3) Once done wait about 10m and feel the tank in the area where you cleaned, you should be able to feel (often it is much easier to feel the fluid than see it) where the fluid may be leaking from the tank. Identify this area and mark it with a grease pencil.
4) Drain the SLICTank channel that is leaking and clean the area on the INSIDE of the SLICTank using the same degreaser and some paper towel. You want the area to be well cleaned and have no standing coolant. The less coolant in the area the better the epoxy will adhere to the surface of your SLICTank.
5) You should now be able to identify the area where the fluid is leaking through, Typically the source of the leak will be visible as a deep scratch, chip or groove in the tank surface, if the quantity of fluid leaking is very small, then it may not be possible to see the source in the tank, but if you can see where it is
6) Please wear nitrile gloves and a proper respirator when working with epoxies and fiberglass.
7) using some 120-grit sandpaper do a light sanding the target area this is to provide a surface for the epoxy to adhere. Clean the sanded area with a degreaser to remove the sanded grit.
8) The Epoxy provided should be mixed in a 1:1 ratio. The epoxy has about a 7m working time at 75F, and longer at colder temperatures (below 70f) The Epoxy will not properly set below 60F, so you may need to use a heat lamp to warm the tank around the patch area and then keep the lamp in place to cure the epoxy. We recommend only mixing about 2-4 ounces of epoxy together at one time for your first applications. You can use the small plastic cups (like for ketchup at In and Out Burger which are 1oz in size) in as measuring cups to make sure you get an even amount.
9) You should mix the two parts of the epoxy 1:1 on a stiff plastic sheet or on a clean piece of smooth plywood, or wood flooring scraps. The flatter the material the easier it will be to fold the epoxy back on itself until you have a uniform color. You can mix and fold the epoxy using a stiff plastic putty knife. You will discard the mixing board and the putty knife after completion.
10) Spread the epoxy over the area where you have sanded and make sure to get a good coat over the suspected leak area. You can work the epoxy fully into any grooves or knicks. You should use all the epoxy that you mixed and spread it over the surrounding area after filling in any crevices.
11) The epoxy is spread do not try to go back and smooth it as that can separate the epoxy from the surface as it may have already started to kick (harden).
12) Wait 2 hours and then using a gloved finger test the epoxy to see if it has hardened. You may need to wait longer if the temperature is lower, and you did not use a heat lamp.
13) Once the epoxy is fully cured you can refill the tank and begin operations.
