Sinister Cooling kit Heads UP

[112motorsports]

For all those who are buying one or will be buying one, when it arrives take it completely apart and re tape all the fittings. I just put one on and it was leaking like a siz. Just thought I would let everyone know not to trust the joints. Hope all is well with everyone.

I second that. Mine was leaking too and I couldn't tighten it anymore it was cross threaded. I called MKM and they sent me a new one.

Did they make you return the one you got first before they would send you a new one? hate to start an install and have to wait to send back mine then wait for them to resend.

Nope. They sent a new one with a shipping label. Annoying it leaked but they have taken care of it. So I am pleased. It was cheaper than the dieselsite with the ball valves was the reason I got it.

Mine was cross threaded as well; thank God I had the Dye to clean up the threads. All is all it is a great kit, just do your due diligence and you will be just fine

[FordWake]

Yup. I like it and they took care of it

I had the same problem with mine. Thought it was cool that it came assembled but found out real quick it leaked. I tried tightening the fittings up but they still leaked. I finally took it back apart and added some thread paste and all is well now.

What I find find funny is the reactions on here to this set of failures versus when the dieselsite filter had 1 failure.

Some background is that there was 1 failure of the "pressed together" "T" fitting, and some people acted like, "OMG mine is gonna fail too". It was comical to read and watch everyone get all up in a tizzy for a single T fitting failure.
A bunch of guys went out and bought new T fittings and couldn't wait to post up about how they did it and how inconvenient it was to have to replace a fitting.

Now the Sinister kit has issues with leaking right out of the box and there have been stripped fittings??


There were FEW confirmed failures (I believe the actual number was 6 over a 2 year period) of the "T" fitting and dieselsite not only stood by the product, they changed their manufacturing process to keep it from happening ever again.
Theres three failures right here in this ONE THREAD. Wheres the pandamonium? The demands for a better product? The letters, the rage?


What gives here?

I am guessing the pretty blue anodizing makes up for the inconvenience. Dieselsite coolant filters are the original and hard to beat.

I didn't have any issues after installing mine with leaks....
