Disappointing Results from Automotive Sleeve

After I put it to the test, I was not impressed with this replacement part. It claims to improve engine cooling and climate control, but I didn't notice any significant difference in performance. The only positive aspect is that it was easy to install. Unfortunately, the cons outweigh the single pro. I would not recommend this product to other hesitant buyers.

Pros
  • Helps regulate engine temperature, improving performance and longevity.
Cons
  • Requires installation by a professional mechanic or individual with advanced mechanical knowledge.

Fits 3.0L 4 cylinder engines

Worked on my Mercruiser 3.0L. The previous thermostat I just bought was at 160°C and it was too hot and my engine was running on diesel. Now my engine no longer runs on diesel.

Pros
  • New thermostat kit for Mercruiser V6 and V8 engines
Cons
  • Not bad but...

Solid Bushing: Engine Cooling and Climate Control

The bushing for this thermostat is a one piece design all the way around. The add-on needs better photos. I needed a sleeve with cutouts for water drainage. At least the seals and the thermostat are still usable.

Pros
  • Replaces part numbers 807252Q4, 23-47508T
Cons
  • Many Parts
