Thermostat Replacement and Cooling System Upgrades ~ R32 Restoration

Thermostat Replacement and Cooling System Upgrades for a 2004 VW R32. This thermostat replacement will cover all 24v VR6 engines. This will also cover thermostat housing replacement and coolant transfer pipe or CRACK PIPE. This thermostat was failing, but some how there was not a thermostat housing leak. This is an extremely common repair on many different Volkswagens. The repair seems to come in two forms, repairing a coolant leak, or fixing a check engine light. A VW with a check engine light? Surely you must be kidding! 😉

This DIY is pretty straight froward and requires only some basic hand tools. I have listed some tools below if you find you are missing anything. Be sure to follow the rest of the R32 restoration and rehab.

thermo2Hey everyone, today we are back to talk about more failing VW parts. The failing VW part was are looking at today is the thermostat on 2.0t FSI engine. This is the engine code BPY found in 2006-2008 Volkswagens. This is a failure that can cause a number of issues from overheating to a check engine light with a code p2181. While we are looking at the thermostat on a 2.0t FSI, this issue and fault are common on many other VW engines.
