Bros, why is my daily overheating?
The car is running hot in traffic, hotter of course when the AC is on...it was 109*f outside yesterday. My CEL flashes at 220*, the radiator boils water occasionally, but the temp-strip on the top of the rad says it's never been over 220*f.
If I can make it to September with this ----, I will live.
- The water pump is 2-years old
- I have a CX racing radiator
- Murray 1.3BAR radiator cap
- Fans are sealed with tape to the radiator (temporary)
- 180* old thermostat checks out okay, a new one is in there anyway

Are the fans coming on?
If they aren't coming on: Disconnect the fan and wire it directly to a battery. If it spins it's the relay, if it doesn't it's the fan itself. Twice I've had a relay to the fan die, and replaced it at a junkyard for $1. Tons of cars use the same relay.
If the fans and thermostat are working it's most likely a waterpump or headgasket.
Edit: Is this a 1.6? Could be the "Cursed Water Plug"

OEM stuff is there.
There could be a phantom leak, but pressure tester says no until the rad cap leaks.
I can see through both the rad and condensor.
All this makes me think the water pump is either not effectively moving water, or there is a leak.

Radiator says (according to "temp-strip") less than 120, but CEL flashes at 120, means the block is hotter than the radiator. I think that points to circulation:
Blockage - foreign matter or air pocket
Pump not working as it should
Check the flow.
