Engine Light - Coolant Overtemperature condition

[NeverSatisfied]

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

Correct, but an oil cooler that’s a fraction of the size us poverty spec GT drivers have had to add to achieve acceptable temps on track. Along with a bunch of other upgrades…

I agree 100%, depending on the track, ambient temps, any engine HP improvement, and how hard you push, the motor can get hot. This last season I sealed off the leak paths around the radiator, lowered the belly pan 1/4 inch in the back to maybe let some more air out of the engine compartment, and added a pint of hyper coolant. Same track and 12degF hotter conditions and it didn’t result in any RPM pull back. I haven’t run in hotter conditions yet as my May run was our last track day so not sure of the overall gain in ambient operation temp yet. Sealing off the leak paths around the radiator is bit labor intensive, but it’s low cost and relatively easy to do and gives a good operating temp delta.

Oh, I also took out the fog light plates and ducted the drivers side of the grill to the air intake.

My fog light deletes have been drilled so air can go thru. I left them like a mesh because I was worried about stones going thru. Anyhow, this Thursday I was at Pacific Raceways and because it was my 1st time I maybe went 80-90%. It also was a hot day. I left it in 'auto' without using paddle shifts to see if the CHT would climb. It didn't. Thinking back, I am also wondering if my sensors went off when I redlined once or twice when I was in paddle shift mode? Maybe that caused the fault to show? This will be an experimental exercise but I seriously think I will add more cooling as knockdown and others suggested.

This is encouraging to hear.

I forgot to ask/mention earlier, a great trick for pulling heat out of the motor between sessions is to pop the hood, and put the heater on full blast with the car idling for about 5-10 min. The heater acts as a second radiator and coolant continues to circulate. Plus all the under hood heat escapes.


I apologize if that’s obvious and everyone is already doing it.

If somebody with Mach1 could take pictures of how the oil cooler is routed to the engine, and whether ford kept a usual coolant-to-oil heat exchanger, that would be really greatly appreciated.

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.

I'm guessing that majority of M1 tracked cars are manuals, which run cooler compared to A10 cars.

I pop the hood but not the rest. I will for sure try it!

Saaaaweeet!
See you there!

If you get a chance, post your best lap video on the 'Mach1 Open Track & HPDE' thread. I put mine up but it's nothing impressive. Good to meet you.

This illustration is for the GT350 but the M1 has a similar filter adapter, cooler line and cooler.

Here’s a pic of the cooler…..

Thank you! Do you have a picture of the filter area by any chance? It's unclear from the diagram whether there is a coolant-oil circuit still preserved or not.

I don’t have pic handy, but there is no engine oil-coolant heat exchanger.

Thanks Greg for that info. But when I was researching the possibility of adding the Mach 1 OEM bumper cooler and all associated parts, I recall seeing the regular water/oil cooler under the filter in the exploded parts diagram.

So it could be that the 350 does not use the water/oil cooler but the Mach 1 does. I am not 100% positive on this. Surely another M1 will post the definitive answer.

As I've posted before, I added a large Setrab 2-pass cooler to my GT, and kept the OEM water/oil cooler. No CHT temp problems anymore.

Stacked plate coolers like that are nice. At least it looks like the Ford OEM is a stacked plate vs tube and fin.

I think the Mach1 has the 4 coolers only. Radiator, Air Engine Oil Cooler, Transmission Cooler & Rear Diff cooler.

You got me thinking, so I dropped the splash shield and took a few pictures. I don’t see the heat exchanger or any coolant lines in the area.
