*1995 FZJ80 with 250k mi.
I have recently switched from a Denso radiator (which I installed 2 years ago) over to the TYC 1918 as recommended by our friends in hot climates. At this time I also took the opportunity to completely flush out the system from the green premix 50/50 over to the Toyota Red coolant. Here are some temps I have noticed after making the switch.
*If you are overheating then this will not fix your issue, there is another problem with your system.
Engine water temps measured with an Ultra-gauge. Modified blue fan clutch with 20k_CST, Toyota RED coolant ratio (2) gallon of RED then the rest distilled water.
Denso Radiator: Ambient temp during readings 90-100F - (I did not have many folded fins and did rinse out the radiator from the backside to flush the dirt from off road every few months)
Average Scenarios and temps:
Now onto what I've noticed when looking inside the filler neck of both radiators.
They are both double row and have the same dimensions - YET the TYC has much larger channels for the coolant to flow through, I take that its cooling capability is better than the denso due to being able to flow coolant at a higher rate.
I highly recommend the Toyota RED coolant along with this TYC. I know our friends in hotter climates run a mixture of (1) gallon RED coolant and the rest water. I decided to use (2) gallons since I do frequent snow and single digit temps in the winter. I also wanted the coolant to have a brighter RED color and not be too diluted.
Also the price on the TYC is great: TYC 1918 on Amazon

Average Scenarios and temps:
- Warmed up idling after starting 190
- Driving around town 190-198
- Freeway driving 185-194
- 4 low crawling 195-215 (depending on engine RPM and fan speed) (I have had the AC cut off 1x while wheeling, low speed, hot outside and a steep climb)
- Warmed up idling after starting 180-185
- Driving around town 185
- Freeway driving 180-185
- 4 low crawling 185-208 (I have not seen it get higher as of yet) (have yet to have any issues with AC getting cut off, as I have not even reached close to the 226F)
