From the engine standing cold the gauge saying its at OT in 30 seconds from start up is imposible (on the engine side of things) It takes FAR longer to heat up even if the the thermostat was completely blocked off.

I have had the Identical thing happen, his lower hose isnt warm yet because IT ISNT WARM CAR HAS ONLY BEEN RUNNING FOR 30 SECONDS, THE GAUGE IS INCORECT "IE THE SENDER IS TOAST"

Man, is 420sx and I the only ones that can read or trouble shoot?

FYI the heat from the combustion chambers will only start to heat coolant up in about 60-90 seconds of the car running, most cars thermostats wont open till about 5 minutes of running, that is why 95% of thermostats have bleed holes so the pump doesnt cavitate and the hot coolant can run from around the sleeves and head towards the thermostat so it can open. The lower radiator hose should only warm up after about 2 minutes or more of the car running, not 30 seconds.

Thats kinda basic, the car isnt overheating, the gauge is incorect.
