This reminds me - I need an aftermarket water gauge. Mine loses ground and floats around sometimes, but when it does work, the water temp is the same as stock.
Some things to add:
-New OEM replacement, regular temp thermostat. Not Toyota, something else. This was installed about a month prior to the rad.
-New Prestone Green (yellow bottle).
-Old OEM hoses.
-Siliconintakes.com 12" slim fan. No shroud, less powerful than stock.
Previously:
-Old OEM thermostat.
-2-yr-old Toyota Red
-Old OEM rad, flushed 2 yrs ago.
-Old OEM shrouded fan.
