If you are running a serpentine belt with a riser set-up and find you have heat cycling it might mean trapped air. The best solution is to build pressure to and the best tool is pump 1777. We designed an impeller with an increased vane count and a reduced impeller vane clearance to take build that pressure. It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids.
We developed this hi flow pump because trapped air can cause overheating in slow speed situation and stop and go traffic. It has been proven time and time again that reducing the cycle time between the heat source and the heat sink drops engine temperatures. It has been reported that people who run the heater line to the port between No. 6 and No.8 heads and not the manifold seem to have better luck freeing the air.

K270 keyboard info that might help you
Color: Black, Size: 1 Pack, Style: Keyboard
This review is a bit long, but has info that might help you. I posted it twice, once for the K270 keyboard and once for the M510 mouse. I have owned a K270 keyboard and M185 compact mouse for years. I bought them as the keyboard/mouse combo that Logitech sells. I have been happy with them. They are still working, but I decided that I would like to have a full size mouse. I settled on the M510 for the new mouse. The M510 mouse works with the unifying receiver. I did a fair amount of research before buying. I thought I could use the original K270 keyboard with the new mouse. I found that the older M185 mouse is not unifying. I thought that was odd because when you look at the seperate K270 Keyboard, it says that it is a unifying keyboard. Why would the combo set have a unifying keyboard but a non-unifying mouse? From what I have read online, when you buy the K270/M185 combo, it is NOT a unifying set. If you buy the K270 keyboard seperately, it IS a unifying keyboard. Since I wanted to get the M510 mouse, I had to buy a new seperate K270 keyboard since the one in the combo set is not unifying. I found this out ahead of time, so it was not an issue. I actually bought 2 each of the K270 & M510, for each of our 2 computers. Did not have any trouble getting them up and running. As a side benefit, the keyboard and mouse each come with a unifying receiver so I have a couple of spare receivers now. Registering them was an adventure. There are two methods to register, a serial number search or entering the info manually. The serial number search did not find any of them, so I did it manually. I did the keyboards first. After you enter the info for the unit you are registering, the registration software asks for the serial number. When you give it the serial number, I does a serial number search and verifies that the serial number matches that unit. This serial number search acutally worked (sort of). It found one of the keyboards correctly, but kept changing the other to a K295 instead of a K270. More on that in a bit. Next I registered the mice. When I got to the point where you select the correct model, the M510 was not in the list. I tried a few different things and finally found a trick that worked. When it asked for the model, I used M525 instead of M510. At the next step where it did the serial number search, it found the serial number was associated with the M510 and corrected the model entry from M525 to M510. Success with the mice. Back to the keyboard. I could not figure out a way around the registration error, so I contacted Logitech support and got a reply back from a support rep named Sharan. After a couple of email exchanges, Sharan was able to get the other keyboard registered correctly - Thank you again for your help, Sharan. I had noticed when I first started all of this that each unit has two serial numbers, one on the box and one on the unit. The two serial numbers did not match. Sharan told me that the number on the box is strictly for inventory use and the number on the unit is the one to use when registering. Anyway, both sets are now working and correctly registered. Happy with the purchase.

Lovely
Color: Rose, Size: 1 Pack, Style: Combo
Love the clacking sound, it’s satisfying, the keys aren’t sticky, it’s a nice shade of pink, comfortable to use. Keys pop off easy enough for easy cleaning and are super stable when popped back on. The mouse is great two, it’s a two-in-one set up with the USB plug in so it controls both which is nice.

An extra separate dongle for the keyboard and mouse would make this perfect.
Color: Off White, Size: 1 Pack, Style: Combo
I picked up the Logitech MK270 Wireless Keyboard and Mouse Combo on a recommendation from our IT guy, and overall it’s been a solid buy for the price.
The keyboard is the highlight. I’ve been using it for a couple of weeks now and it’s been great. It’s quiet, responsive, and just works every time without any issues. Setup was simple and I haven’t had a single connectivity problem. I do wish the rear feet lifted it a bit higher. Even fully extended, it sits more flat than what I was used to. That said, I’m adjusting to it and it hasn’t been a dealbreaker.
The mouse is where it falls short. It gets the job done, but it definitely feels a bit cheap compared to the keyboard. Lightweight in a way that doesn’t feel premium, and just not the same level of quality overall.
One thing I really wish they included is a second dongle. I’d love to keep the keyboard connected to my main PC and use the mouse with my laptop, but with only one receiver that’s not an option out of the box.
All in, this is a reliable combo from Logitech. The keyboard alone makes it worth it, especially at this price point. Just go in knowing the mouse is pretty basic and you’re limited to a single receiver setup.

Perfect solution to a common problem
Size: 6-Foot Cable, Style: Rotating Plug - Single Pack
Power strips that have low profile plugs are fairly easy to find these days, but it's a lot more difficult to find one where the cord leaves the plug in the direction you need it to. This solves that problem. you can turn the prongs on the plug and any direction you need them to go. And it doesn't hurt that the design is attractive and appears to be fairly sturdy. I've been using mine for over a month at this point and I'm very happy with it.
