lowkooler high flow pump 1745 for the Jeep and AMC engine has a CNC machined billet impeller designed with an increased vane count and a reduced impeller clearance to achieve greater flow rates, higher block pressure. A Type II Class II military grade anodize surface coating protects against corrosive fluids. 

We developed this hi flow pump because Jeeps tend to overheat in traffic and on the trail. Tight engine space and limited airflow plague the cooling system but it has been proven time and time again that reducing the cycle time between the heat source and the heat sink drops engine temperatures for slow speed rock crawling and stop and go traffic.

Make your Cappuccinos!
Color: White
I purchased this after a trip to France. I drank a lot of cafe cremes, pretty much like a cappuccino, and decided I need it in my like every day. Easy to use. Didn’t come with instructions but I was able to figure it out. Takes a little time but works well for what I want to achieve. Love the glass pitcher. Doesn’t spill when pouring. It’s very quiet while frothing super easy to clean. I love it!

Great frother
Color: Matte Black
It makes a great milk froth and heats well. One thing however, in spite of respecting the line limit it spills out and you have to clean the whole thing. So don’t fill it up to the line limit.

Thick foam for Cappuccinos
Color: White-Stainless, Color: White-Stainless
Comes with sevaral options including thin and thick foam, hot milk and cold foam. I used the thick foam for cappuccinos and I was impressed by the consistency. Not so much noise and easy to clean. The frother tools come off easily for cleaning the pitcher.

Very slow--5+ minutes to froth and warm milk
Color: White-Stainless
Pros-- Makes nice froth and warms the milk. Both froth settings produce the same kind of froth. it's relatively easy to clean-- usually just a strong rinse will do. It does fine in the dishwasher too. The noise level isn't bad. Cons--it takes between five and six minutes to froth milk. It is very slow. I can froth latte art milk on my espresso maker in less than a minute, by comparison. The forth it produces is too thick to make any kind of latte art.

Quality
Color: White-Stainless
What really impressed me is how fast it works—in just a couple of minutes, I have hot, creamy milk with thick, rich foam. The texture comes out smooth and fluffy, just like a coffee shop. It’s super easy to use, and cleaning it is quick too. I’ve used it for lattes, cappuccinos, and even hot chocolate, and it works perfectly every time. Definitely worth it if you want something quick, easy, and makes great foam in large amounts
