CSF High Performance Radiator for GR Yaris

CSF's radiator for the GR Yaris is a drop-in replacement with a 2-row, 42mm core. It suits cars that get driven hard on the road and taken on the odd track day, where a little more cooling capacity keeps temperatures stable.

Key features

• 2-row, 42mm core using CSF's B-Tube cooling tubes
• 5mm tall multi-louvred fins for more surface contact
• 100% aluminium, TIG-welded, with a hand-brushed satin finish
• CNC-machined mounting brackets and OEM-style inlet and outlet
• Pre-plugged 1/8in NPT port on the right-hand tank, ready for a temperature sensor
• Foam strips fitted top and bottom to seal airflow through the core
• Every radiator individually leak and pressure tested
• Replaces Toyota part 16400-18050 (GR Yaris) and 16400-18060 (GR Corolla). CSF part number: 7233

CSF or PWR?

Both are direct-fit aluminium radiators. The CSF is the more affordable option and has a sensor port ready for a gauge. The PWR 32mm radiator is UK-made and aimed more at sustained track use. Get in touch if you're not sure which suits your car.

Fitting at String Theory Garage

We can fit this in our own workshop and check everything over before the car goes back to you. Get in touch when you order and we'll book a slot. See our workshop services for what else we do.

Questions we get asked

Can I add a coolant temperature gauge?
Yes. The pre-plugged 1/8in NPT port on the right-hand tank is there for exactly that.
