Billet Aluminum Thermostat Housing for 4.0L 1GR-FE

Here is an update top part of the housing.

 

Man, you need a build thread. Looks like a fun project.

 

You think? I dont know what it would be called lol

 

lol. Here’s some:
Not another boring taco thread

Did you make changes to the thermostat bypass circuit.

 

Not really there will be 2 lines taped to the billet housing 1 for the rear circuit and one for the oil cooler.

 

If you simply removed the oem thermostat, and did not sort out blocking the bypass ports, coolant flow thru the radiator will be substantially reduced. The bypass circuit is a temp controlled means of more quickly warming up the engine, and then as temp increases, ensures proper flow thru the radiator.

 

Hello everyone! Sorry about being MIA! Had a job change and moved out of state so things have been hectic!

We are working on the 2nd version to clear the TRD/Magnuson supercharger setup! Anyone that had bought one of the 1st versions shoot me a message!

 

2nd gen housings are now available! We are trying to find someone with the Magnuson/TRD supercharger to confirm that it clears the belt.

 

What do you have to say to address the increase in temps that people are seeing due to the combination of your housing and thermostats compared to OEM? Multiple posts earlier in this thread clearly provided evidence/testing and sound logic as to why it's occurring and the design flaw. Your original description has been shown to be misleading, sure it's more durable than plastic and looks cool but it's not helping temperatures.

Never had an issue with just about 200k on the stock thermostat/housing and I keep a $30 OEM/Aisin spare in the truck. Always a good idea to have spares and tools within reason if you're doing long trips or to remote locations.

 

We have not seen any increased temps on any of the test vehicles… we are keeping record of it though.
