FREQUENTLY ASKED QUESTIONS
BAR’S LEAKS RADIATOR STOP LEAK TABLETS
P/N HDC
Can Bar’s Leaks be installed in existing antifreeze?
Yes, this product is specifically designed to be directly added to the cooling system with out having to
flush out the antifreeze.
Will Bar’s Leaks work in the new extended life antifreeze?
Yes, Bar’s Leaks is compatible with both conventional green (silicate-based) and extended life red/orange
or yellow (OAT) antifreeze.
How does Bar’s Leaks work?
Bar’s Leaks will seal external, internal and coolant to oil leaks. Once installed, the Bar’s Leaks particles
shrink up to 15 percent. On an external leak, the tiny particles flow to the point of the leak. They then
collect at the outside of the seepage and build inward. Internal leaks, the Bars Leaks particles will burn
when subjected to the 5000°F heat of the combustion chamber to seal seepage and small cracks. On
coolant to oil leaks, where coolant can seep into the crankcase contaminating the oil, the tiny Bar’s Leaks
particles will seal the pores in cast iron and aluminum preventing seepage.
How long does it take for the Bar’s Leaks to work?
We recommend you drive/idle vehicle for 15 to 20 minutes. In most cases the leak will be sealed with in
this amount of time. If the leak is not sealed, a second application maybe required.
Will Bar’s Leaks plug my heater core?
No, the tiny particles will pass through a 24-gauge mesh screen which is the spec for the BIG 3
car/truck manufacturers. They say that any product installed in the cooling system must pass through
this screen. Bar’s Leaks is one of only a few stop leak products to pass this test and to be approved
by the vehicle manufacturers. Note: If using Bar’s Leaks to stop heater core leaks, make sure you
turn your heater control to HOT. Some vehicles have a valve that controls coolant flow through the
core.
What if I don’t have a radiator cap?
If vehicle does not have a regular radiator cap, remove top hose where it attached to radiator and insert
tablets in hose and then reinstall hose.
How do I pre-dissolve tablets?
Just add tablets to warm water.
What are the dosage recommendations?
One package treats systems up to 3 gallons. Use 2 (two) tablets per gallon of coolant capacity.
