Water Neck Modifcation Service - 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. 

Parts Included:

• Modified water neck with fill adapter
• New radiator cap
