Hey All,
After some recent maintenance I'm fighting issues with engine over heating. Coolant temp shot up to 239 while driving the other day after having been on the road for most of the afternoon.
Since then I've given some love to the cooling system, I run in the 190s while moving but as soon as I idle, the temperature creeps up past 210. Coolant heats up even faster with no apparent upper limit when AC is on. At the moment, I’m unable to safely drive the vehicle without watching coolant temp like a hawk.
Here are some details I've put together:
Maintenance History:
Problem recently started after I:
In response to overheating I have:
Next up to try:
* Replace vacuum hoses and clamps. They seem to be crusty and falling apart. Not sure if this is related.
If anyone has any recommendations on other things to check/try I would really appreciate any guidance.
Thanks!
After some recent maintenance I'm fighting issues with engine over heating. Coolant temp shot up to 239 while driving the other day after having been on the road for most of the afternoon.

Coolant heats up even faster with no apparent upper limit when AC is on. At the moment, I’m unable to safely drive the vehicle without watching coolant temp like a hawk.
Here are some details I've put together:
Maintenance History:
- Radiator and hoses replaced 54,000 miles ago with “Liland” aluminum.
- Water pump/gasket replaced 54,000 miles ago with OEM.
- FAN Clutch/Thermostat replaced 54,000 miles ago with AISN
- Replaced Heater-Ts with brass connector 54,0000 miles ago.
- Flushed coolant and used 50/50 Toyota Red 54,0000 miles ago.
Problem recently started after I:
- Replaced Starter
- Replaced gaskets for coolant at inlet/outlet at rear of engine coming from heater-Ts.
- Having fuel injectors serviced.
- Had intake manifold cleaned and replaced gaskets.
In response to overheating I have:
- Replaced thermostat with OEM
- Coolant hoses hot, coolant seems to be circulating.
- Heater on full blasts hot air and helps bring coolant temp down. This tells me the water pump is okay?
- Fan Clutch:
- After driving for awhile and shutting the car off, fan stops spinning within 1 second. Tells me fan clutch is okay?
- No free play in fan.
- Burped with cap open and ran engine at 2400 RPM with heaters wide open.
- Attempted multiple times and drove with heat open.
- Replaced Radiator cap.
- Drained coolant at radiator and flushed through a few gallons of distilled water (ran the car, drained). Refilled with “Peak” brand pink concentrate blended to 70/30 with distilled water.
- AC Fan appears to start/stop correctly.
Next up to try:
* Replace vacuum hoses and clamps. They seem to be crusty and falling apart. Not sure if this is related.
If anyone has any recommendations on other things to check/try I would really appreciate any guidance.
Thanks!
