You may have shorted your radiator fan, check fuses and fan function. If you have not done damage already then get it fixed quickly.

you're in trouble, when temps rise that high you've damaged something. If you ever see the temp start to rise shut the engine off as soon as possible otherwise you'll damage the engine.

I pegged the temperature gauge at the race track twice. And she's still kicking.

i was stuck in traffic on the highway when it happened. i turned the heat all the way up & it came back down to the middle. it was only that high for a minute or less. but yeah, i know its not good :(

I'm curious about this as well because I don't think my radiator fan is working. Hopefully someone can chime in with their experiences with the fan

Someone else here did a FMIC install and shorted their radiator fan. If I recall correctly, there are three wires going to the fan, ground, low power, high power. They somehow shorted the high power one, so the fan wouldn't turn on fully when needed. Pull the fan connector and use a meter to test it, you can also test the engine side of the connector if you do it quickly (use a meter on the contacts before the engine gets too warm).

I think the fix was a new fan as the regulator and wiring was built in.


edit: this might sound stupid, but make sure you properly reconnected the fan connector.

Is the fuse really that inaccessible? Under the fuse box that's in the engine bay? I ran the car but the fan isn't going on at all.

Nearly pegged mine once at a trackday and also driving up Pikes Peak a bit too quickly apparently.
That was 60K+ miles ago, engine now has 115K and still runs perfectly.
