This product is completely useless without the special thermostat kit that must be order to get this to work.  If replacing a standard crusader housing you can expect to replace your hoses also as they are 1/4 in different size than stock.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Work perfectly

Works perfect you don't need to have a hole for the sending unit for the temperature you can put the sensor on the intake.
