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.

A better topper from a company I trust
Color: Black, Size: Twin
I have a memory foam daybed that has seen better days. The top layer has started to shift from regular use, and I wanted something that would help hold it together. The Bedsure Twin Mattress Topper does exactly that and made a huge difference right away.
This is a high quality, well constructed mattress pad. It fits securely over an extra thick mattress and stays in place. The corner bands under deep pockets are strong and keep everything aligned without slipping. The measurements are accurate. There are instructions to dry it, then leave it out to expand. There was no weird smell. What you see is exactly what you get, in a good way.
The cushioning is even and comfortable, and the fabric feels thick and smooth. It adds structure while still improving comfort. It has a more premium look and function than expected, similar to what you would find in a Five-Star hotel. It feels expensive.
I also appreciate that the color is not white. It looks cleaner over time and feels like a more practical choice. I have used several Bedsure products, and the quality has been consistent. I also like that it is a woman founded and owned brand, and they continue to improve their products.

adds a touch of comfort!
Color: Black, Size: Queen, Color: Black, Size: Queen
I ordered this mattress topper for our guest bedroom. It is soft and adds a little plushness to the existing mattress.
I ordered the queen size for our queen size mattress. It fit well, without much overlap from the mattress topper. The topper has elastic corner bands as well as the fitted sheet like band around the edge, so the topper should stay in place.
The color is black, as shown and if you use light colored sheets, it will likely show through. To combat this, I used a white mattress protector overtop of the pillow topper. You cannot see it through our protector and white sheets.
The topper is more like a padded mattress protector than a true topper. It reminds me of a pillow top, it's not foam just filled to add softness to the mattress. I think it's a great addition, it adds a little height and comfort to the mattress.
Overall, I think this is a nice upgrade to our guest room. It fits well, and serves its intended purpose. I would recommend to anyone wanting to improve the comfort of their mattress.

Try it but have lower expectations
Color: Black, Size: Queen
Pros:
-fairly heavy
-fits right
-soft enough to dream on
-not too expensive
Cons:
-kinda lumpy feeling and that’s hard to shake
-not the classiest wrap/attachment
-a little stinky out of the box that can take a while to offgas or whatever
It definitely upgrades a futon mattress, even if it doesn’t want to bend easily with it. It’s meant for a stationary mattress.

Feels Like Sleeping on a Cloud
Color: Black, Size: Queen
This mattress topper completely transformed my bed. From the first night, I noticed how much softer and more comfortable my mattress felt. The pillow-top design adds a plush layer of cushioning without making the bed feel overly soft or unsupportive.
I was especially impressed by how breathable it is. I tend to get warm while sleeping, but this topper stays comfortable throughout the night and doesn’t trap heat. The moisture-wicking fabric is a nice bonus and helps keep the bed feeling fresh.
The deep-pocket design fit my mattress perfectly and stayed securely in place without shifting around. Installation was quick and easy, and the black color gives it a sleek, premium look.
After fluffing up, it provided just the right amount of extra comfort and made my mattress feel much more luxurious. For the price, this topper offers excellent value and has greatly improved my sleep quality. I would definitely purchase it again and recommend it to anyone looking to add softness and comfort to their bed.

Feels Like Sleeping on a Cloud — One of My Favorite Bedsure Products Yet
Color: Black, Size: King
I’ve had really good experiences with Bedsure products over time, so whenever I get the chance to try another one I usually do, and this mattress topper definitely did not disappoint. This one went on my mom’s king size bed and the difference was noticeable immediately.
The topper has a soft, cloud-like feel while still giving enough support underneath so you don’t just sink straight through it. It added a much more comfortable layer to the mattress and made the bed feel cozy and inviting without being overly heavy or hot.
I also appreciated how easy it was to put on. The deep pocket design fit securely over the king mattress without struggling to stretch the corners, and once it was on, it stayed in place well through the night.
The material feels breathable and smooth, which is especially nice for warmer nights. My mom commented that she slept really well with it and woke up feeling more comfortable than usual, which honestly says a lot.
Overall this feels like a high-quality mattress topper that makes a bed instantly more comfortable. Bedsure continues to be one of those brands I trust for soft bedding and reliable quality.
