3SX Twin Turbo COOLANT Line Kit
with Modified Water Housing

The latest innovation from 3SX! We now offer custom coolant line kits for both TD04 and TD05 turbos! These custom kits use stainless braided lines offering much more flexibility and longevity than the factory lines which use a combination of rigid lines that can corrode and rubber lines that can dry-rot and leak.

Modified Housing: The kit includes a custom modified thermostat housing (all three pieces) which has been modified with fittings to accept the thread-on lines, which not only looks better but makes installation easier, especially if you are in-and-out of your engine bay regularly. This kit pairs great with our TT Oil Line Kits.

NOTE: Second Gen engines (93-99) will need to slightly modify the front head to clear the front fitting - it's just a matter of filing/grinding down a tab (nothing connects to it on the front head) as shown in the picture below. The 91-92 heads do not have these bolt holes so do not need the modification - it's one of the cam angle sensor mount bolt holes.

OPTIONS!

Turbos - We have the kit available for both TD04 turbos or TD05 Turbos.

Coolant to Throttle Body - We can set up the kit to route the coolant through the throttle body like the stock setup, or to bypass the coolant passing through the throttle body.

Polished Housing - We offer the option of getting the housing polished or not. The polished option is significantly less than getting just the polished water housing from our 3SX Polishing page.

NOTE: This kit will NOT work with the larger 3SX Turbos (Terminators, Dominators, Annihilators) as they are a T3/T4 cartridge based turbo with TD05 housings, so the line fittings are different.
