Focus RS / ST170 billet thermostat housing

Description

Billet thermostat housing for the mk1 Focus RS and ST170
Completely machined out of billet aluminium and profiled to save weight and look good
This replaces the plastic thermostat housing that is liable to crack
This version still has to bolt onto the spacer plate, if you havent got this or need a new one i sell them seperately
Comes supplied with the 3 mounting bolts,main housing,top thermostat housing and water pipe connections

The water take off on the side uses an 1/8npt thread so you could use an AN type fitting for braided hoses
The heater pipe connections will be supplied fitted as it needs sealant to seal the 2 surfaces

Uses standard ST170/Focus Rs thermostat and bolts up in the exact same way

This housing will also fit the ST170 engine

Please note

****

If you select the option for the ST170 housing to have a sensor boss this will need to be machined into the housing,if you are on a tight timescale please contact us beforehand
usually we will try to get this feature machined within a couple of days after the order is placed

The only difference with the options between the 2 housings is so we can supply you the correct length bolts, it is the same housing that is used.

We do not advise using the cheap thermostats from euro car parts,these do not have a thick rubber sealing ring like the original ford one and do not seal properly
