I got my latest replacement for the replacement of the original one just over a year ago and had not done any offroading until this last summer up in Colorado. All had been good but now I am smelling antifreeze since we got back but I can not seem to find a leak. Keeping my eye on it and will see what happens.
This is from RPM's supplier. Still had to pay for it thou, even though it started leaking within 2 years of getting it as a warranty for the first one.
