Water Neck Modified - Gen4 Gen5 3SGTE

You must ship your water neck to us after placing an order for this part. We need your core to modify and ship back to you.

This is the factory water neck off a GEN4 or GEN5 3SGTE.  Most people ask: Why can't I use this water neck in my MR2?  Well, what this water neck is lacking is a coolant filler neck since the GEN4 comes out of the FWD Toyota Caldina. What we do is modify the existing water neck to accept a coolant fill neck. This is the easiest solution to install a fill neck in a MKI or MK2 MR2. 

Yes this part is more costly than our competitors but we include the following parts which are REQUIRED to install the water neck

Parts Included:

  • New heater core hose
  • (2) Clamps
  • New radiator cap
  • New water neck gasket

This is also the water neck included in our GEN4 DIY kit.
