When swapping the turbocharged inline six 2JZGTE into the chassis of your choice, cooling will always be a big deal. In vehicles like the 240Z or 240SX, triple pass radiators with slimline fans will do their part to cool down your 2JZGTE. As the cylinder head is aluminum, temperatures above 215 degrees fahrenheit may damage or warp the sealing capability of your head and head gasket.
Today we’ll be installing a Mishimoto triple pass cooling radiator part number MMRAD-SUP-93TX, in a 1994 Lexus SC300, along with their fan shroud and radiator hoses.
To begin our how to install a 2JZ radiator article, disconnect the negative terminal on your battery. If you have the factory stereo still, now is a good time to find your radio code.
Reach under your vehicle, and undo the lower engine panel by undoing the 10mm bolts that run across the front of your SC300. Pull down on this panel, and open the radiator cap, and then your radiator petcock to drain the coolant into a bucket. Once you have the radiator drained, it’s time to disconnect the upper hose on our how to install a 2JZ radiator writeup.
Undo the clamps that connect the upper radiator hose, and then pull off the stock upper hose all together.
Now with the upper radiator hose disconnected, you can move onto the lower radiator hose. Disconnect the lower radiator hose from the water pump outlet only, do not disconnect from the radiator.
With the lower hose disconnected you must now undo the 12mm bolts that hold the radiator mounts in place. There are two ends that secure the stock radiator in place, just undo the 2 12mm bolts and now you are ready to remove your stock radiator.
You can now pull up on the radiator and lift the entire assembly out of the car, along with the radiator hose. Pinch the hose shut or just hold it the right way so it doesn’t spill coolant all over the place. Just walk over to your drain bucket and allow the remnants of your stock radiator to pour out.
With the radiator now removed, take this time to clean up your engine bay in preparation of your new Mishimoto radiator.
You can really tell the difference in quality and cooling power once you get these two radiators side by side.
We’ll also be installing a set of Mishimoto hoses in red ( MMHOSE-SUP-93RD) to add a dash of color to the engine bay. But before you get to clamping on those replacement coolant hoses, take the rubber isolators out from under your stock radiator. Install them on your new Mishimoto unit, and now you are ready to wash your radiator.
Yes you heard us right, flush your new radiator to remove polish contaminants and any metal shavings that may be located from the finishing production touches. A glance inside our new radiator reveals quite a bit in the way of metal shavings. Don’t let these become part of your engine’s coolant system.
Making sure you have everything lined up, slowly lower your new triple pass Mishimoto radiator into your 2JZ swap. Make sure the rubber isolators seat firmly into the radiator support. Reinstall your radiator brackets and the 12mm bolts that hold them in.
Connect the lower radiator hose to your water pump outlet pipe, and then the upper radiator hose next.
Now you have completed our how to install a 2jz radiator writeup, don’t forget to fill it up before you start it.
