1996 UCF21 with IUZ-FE overheat last night
Members,
It is with great difficulty I come to post that my 1996 Celsior had overheat last night. I noticed the temperature rising above the half gauge level. It rose to 3/4 before I could pull aside to safety.I shut off for 20 minutes to let the temperature decrease and then topped up with water till I reached home...
This morning, with the radiator cap off I left the car idling, and the temperature rose rather quickly, when it reached to the half level, I saw steam escaping from the reservoir...When I shut the vehicle off before giving it time to rise above half, coolant was regurgitating from the reservoir.
I pulled my engine oil stick, the oil was a bit lower than usual. But was not of a milky colour ( oil and water not mixing)..
**Points to note*
Engine Coolant Temp Sensor changed in July 2013
Hydraullic Fan is the stock fan
This is the first time this has happened
The only modification made was that I placed an additional fan run direct to the front of the condensor....which honestly, cannot cause an overheating problem...
I would appreciate any feedback. Thanks guys..

Drain the rad, pull it out and flush it with power washer.
At the same time, replace the fan clutch and thermostat and housing then properly bleed the system. When filling it back up.
If it were me I'd probably replace the rad if it is still original and have a hard look at the water pump.
If the above doesn't fix the problem you could have a blown headgasket. Not common but can be checked with a exhaust sniffer at the rad cap, and/or doing a compression and leak down test.

Fan clutch ? Probably you overlooked that I made mention tht I have a Hydraullic Fan.
This video posted 2 weeks ago, shows how my fan works at cold.

actually, an electric fan could contribute to an overheating problem if it was hooked up backwards polarity and therefore not helping the cooling, while blocking the condenser somewhat.
