# 3837335 Coolant Pipe | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta coolant pipe from the Cooling System group, weighing 0.395 kg and listed for a single TWD series application. It supersedes part number 3835378, as does coolant pipe 3837337 at 0.277 kg, so the earlier number now has two replacements and the right one depends on which run you are renewing.
