Description of M31 Cooling Internal Passages Radiator

Refills coolant by creating a vacuum in the cooling system without creating air bubbles. Air bleeding in the cooling system is no longer required, significantly improving work efficiency. Large internal coolant passages allow fast coolant flow, refilling cooling system in a few minutes. Cone adapter applicable size range from 0.6" - 1.7", fitting most radiators and recovery tanks.

Improved Automotive Cooling with Ease

When I tried this cooling tool on my car I was impressed with how easy it was to install. The passages in my radiator were clogged with residue and causing my engine to overheat... This product quickly solved that problem by instantly improving my car's cooling performance. The only downside was that it took a little longer than expected to ship to me, but the results were worth the wait..

Pros
  • Easy installation and improved cooling
Cons
  • Slightly slower shipping

Game-changing cooling tool for Automotive diagnostics

Using this radiator, our team found that it significantly improves the cooling efficiency of our vehicles. It allowed us to measure accurate readings from test and measurement tools without any heat-related issues... The product is durable and easy TO install. However, the price is relatively high compared to other similar products in the market..

Pros
  • Efficiently cools internal passages of a variety of industrial machinery, leading to longer lifespan and improved performance.
Cons
  • Mostly okay, but...

Better than Snap-On at a fraction of the cost

Works great, creates stronger vacuum than Snap-On and fills much faster, passages need to be much larger. My only complaint is that there is no check valve on the air line and it is the top that pulls the unit down. I just flipped this section and added a valve and it's perfect. It looks a little kinky but who cares, it's cheap and it works.

Pros
  • Pressure and Vacuum Tester
Cons
  • No Automatic
