Engine Light - Coolant Overtemperature condition

[IanKar]

Sweet!! Yea temps are going to be perfect. What are you driving? I am in a 2022 Fighter Jet Gray Mach 1.

I think you'll be able to ID me from the picture attached Looking forward to it

Saaaaweeet!
See you there!

I thought the reason Ford put 5000 coolers in the MACH 1 was so it wouldn't have any cooling problems.

^^^^^^
This….in Fact they made a big F’n deal how much better it’s supposed to be compared to a GT.

It disappoints me to see this on a Mach, especially with 2 upcoming track days. Sonoma in August is typically 90 (32.22 C for my Canadian friends ) Weathertech (Laguna) in September will be cooler 70-80. It’ll be interesting to see what happens.

(I’m a moron hack and I managed to run my Lemons car 15 hours straight on track in 105+ degree weather without overheating.)

You’re going to tell me professional auto engineers can’t figure out how to make this thing run for 30 min without overheating, shame on you Ford.

It’s not an oil cooling problem in the M1, seal off the air flow to the radiator and you’ll see CHT temps recover much more quickly after those runs on the straights where the A10 is keeping the RPM’s up. There are big gaps around the radiator, sealing those up helps a lot. At Sebring, I was getting RPM pull back 15 to 20 minutes into a session at 75 deg ambient. After sealing up the air flow to the radiator, I experienced no pull back at 85 deg ambient.

Any insights on CHT's? How high did they go?

This was a morning session in May, about 80degF, CHT on the overlay. Later on in a session, the temp will climb a bit as well with ambient, but it seems that if the CHT recovers quicker, the ECU is less likely to pull RPM.

Cool video...what software & hardware you using to record?

Tomorrow I am on the track again but this time I am going to use my paddle shifters and my performance Shift Indicator is set at 6500 (Forscan to get this active in A10). I'll be watching the temp gauges as well. I have a meet with Ford in about 2 weeks to discuss this and I will be asking about the options. Radiator sealing and additional oil cooler. Someone said that adding the cooler solved his problem. But I'll tackle this step by step.

Irrespective of what the problem is, the Mach1 HP is a track package and should handle it either way without me doing any modifications especially if my sessions are no longer than 20 min. When I get back I have a few weeks to mess with this and I am for sure going to look at sealing up the rad as you mentioned.

It’s unfortunate the Mach 1 isn’t up to the task, but it does make sense when I look at the laundry list I had to throw at my base GT 6MT to keep it cool and stay out of derate due to high CHT

That's a pretty bold claim based on one incident. Let's not blow this out of the proportion. I don't remember others mentioning any such problems about their engines overheating on the track.

Interesting. I've tracked my base GT a few times. Not a big track, 1.3-mile 13 corner course. lots of hard braking and acceleration, back stretch up to 120 mph. Logs showed the CHT never going above 100c, coolant below that. 97c, 99c somewhere around there. 10 laps.

Its all about the use case, specifically the revs. If you are high up in the rev band for a long time, holding high revs in a lower gear for example, it can get hot for any Coyote. The Auto trans will try to hold in lower gear and keep the revs up, more so depending on the mode.

Ambient temps are going to be a factor too.

Keep in mind the M1 has the oil cooling parts from the GT350 and is different from the GT.
