In the racing world, we call “heat soak” when your engine detunes due to heat. The super chargers and turbos get heat soaked, than you get lower power. So your best laps are always at the start before you get heat soaked.

Also even though I've got water cooling going to my turbo, I still let it idle for 10-15 seconds after coming to a stop just to help the center cartridge cool down a little bit better. It's small things like these that ultimately prolong the life of our vehicles. And when you add all these precautions up, it can mean driving your car for a year or more before it really *dies*.

Hi Eric, Where I live is usually really hot and I also open the hood and put a floor fan facing the radiator. Even if the car is shut down if you can cool the water in the radiator it will cicle, slowly but it will because the “heat convection” effect. Some german cars a more effective system to allow the car to cool properly after shutdown, where the radiator fan keeps on for few minutes after the car is shut down. My father and I where able to recreate this system on my old ‘94 Civic. Basically you need to give direct power to one of the relay prongs in order to activate the circuit of the fan and water temp. What you want is keep the circuit alive after key shut down, the fan will spin until the temp is lowered and the fun will shut itself.

I've been doing the same thing for years. I occasionally open the hood of the Vette after driving. Usually open the hood of the Camaro, rarely open the hood of the Crown Vic, and almost always open the hood of the BMW to dissipate heat and prevent heat soak. BMW parts are plastic and expensive to replace and it runs very hot with a 219 °F thermostat, all aluminum block. The Vette runs really cool with a 160 °F thermostat and cast-iron block, but those wires and rubber hoses are pretty brittle after 27 years of age. Camaro runs pretty normal with a 195 °F lots of plastic parts with aluminum engine under that hood. The P71 served years as a patrol car and is pretty robust with extra cooling capabilities, so it can take a hit.

I think it depends on the vehicle and driving conditions prior to shutdown. My Tacoma 4-cylinder has gaps around the hood (not sealed) and no heat/sound insulation underhood so I don't even think about extra cooling for that. However, the 1995 Corvette would probably benefit from extra cooling after shutdown for several reasons: -- the 1990s Chevy LT1 was designed to run hot for emissions purposes (electric fans don't kick on until 228F) -- the iron block holds a LOT of heat -- the hood is partially sealed at the wheel wells and the firewall. If the car has been idled before shutdown, the big iron block could be 228F or hotter when it stops running, GAH. (If it's been moving along with some airflow it usually stays between 190-205F.) So I know for sure that everything under that fiberglass (FRP) hood cooks for hours after shutdown... the vacuum lines for the cruise control have become rough and brittle, the hood is still very hot 2 hours after shutdown, and the temperature inside the garage increases approx 10-15 degrees F after I drive that car. (The Tacoma does not cause such an increase in garage temperature, maybe 5 degrees F at most.) The problem with opening the Corvette hood is that the hood release cables are known to wear and break after 25+ years -- this car has emergency cables installed, but still I want to preserve the originals as long as possible and extra wear/tear is not desired. My solution is to place a small fan on the ground in front of the car and run it for 1 hour but I only bother with this if the engine temp is above approx 215F when shut off. I have machine sympathy as well. I bought these vehicles because they are excellent for doing exactly what I need and they are mechanically robust... and they will last nearly forever the way I treat them. Yes I get on the gas occasionally because that's good to clean out carbon. Thanks Eric for the thoughtful video.

You are dead right about the 195F operating temp of the LT1/4. & The lower temp thermostats only cause other problems since the engine was designed this way (unless you've rebuilt with new clearances for lower temps). I lost a lot of fuel efficiency when mine stuck wide open, probably mostly due to ECM response to the reduced temps. A timed rad fan override relay after ignition shutoff or a "blower" will help air thru that little engine compartment. I'm sure a house fan is fine but most of the air will run over the hood thanks to the design. It's worth it every time you park, regardless of what the dash says, keep doing it!

@@jameslarson7452 When I said I put the house fan on the ground, I mean the fan shroud is literally touching the garage floor. So most of the air is in fact flowing underneath the car to cool things underhood. Thanks for your reply :thumbs:

In my daily I don't care much. But if I'm in my supercharged Miata driving like a nutter, I usually take a few minutes of driving kindly, but at speed to let the engine cool down before I stop and park. It gets REAL HOT if I push it.

Heat soak can also mess with electronics too. Materials being hot affects how they conduct electricity. First thing I do with old vehicles is clean up electrodes and grounds and give the engine a good wash. Dust and oil all over your block can be a surprisingly good insulator, i've had weird electric problems go away after a good clean up.

Just go drive the car around gently for a few minutes after driving hard. That should be sufficient. There are millions of cars out there that are “heat soaked” multiple times a day and run for hundreds of thousands of miles.

Exactly, but I was speaking more about the custom vehicles that I built, not everyday vehicles where heat soak was engineered into their design. This video was more to inspire a conversation about heat soak, not name it is an issue that people have to deal with. Thanks for the comment.

If you plan to keep the car for more than 20 years lifting the hood helps. I had to replace numerous spark plug cables and distributor once on my 30 year old car plus some wires became brittle , all because of heat soak. I live near the ecuator so its a big issue

My accord definitely doesnt get that treatment. Been doing it for about 2 maybe 3 years and it fine. Gets redenned up once every few months and then turned off for another few. Reason for letting the heat soak in it is to let the moisture go away. Then a reasonably air tight cover is put over it. Car is all original bar an alternator, clutch, brake disks, spark plugs, filters, oil, tyres and an ignition which was accidentally damaged in 2003. 99 accord, f18b2 engine, manual 5 speed. 230k miles too and still starts (after months of sitting) like it was only running yesterday. That car has never failed to start ever and has never left me or my family stranded. Very little rust too which is surprising for that generation. It got undersealed multiple times. Interior is almost perfect. Hondas have to be some of the most under appreciated cars in existence

I am not an expert, but I have seen some plastic parts become brittle. Things like clips, cable conduit and other little parts. However, I don't really think too much about it. If something breaks, I'll either leave it alone (if it still works and is not a safety issue) or I'll just replace it.

i had a heat soak issue with my build. The MAT sensor was right before the throttle body, coincidentally very close to the radiator. After a long drive, the sensor would take in this heat soak and read higher than normal temps at idle, causing it to lean out. I had to move it down right after the intercooler to fix this issue

Unless the car have mods, you won't have ever any trouble with heat soak, as the cilinder walls (sleeves?) are the hotter part and they must not be much hotter than the oil already... and the oil is a huge mass compared to the metal that is a fre degrees hotter and will absorb it. On the other hand, rapid cooling from 90-100ºC to 20ºC will make trouble with time...

Was having a heat soak issue with my 1997 Geo Metro. It wouldn't crank after I parked it until the engine cooled off enough to do so. I just removed the thermostat to see if it helps in the future. Fingers crossed.

@ETCG1 I have that same "mechanical sympathy" gene, expressed in physics/logic and at the extreme end of popping the hood whenever possible (opposite in winter - to retain heat for restart to minimize cold starts).

1) Got a 2000 Prelude (original owner), never heard the fan stay on after engine shut off, had an issue on a '96 Civic where the fan wouldn't shut off after taking it up a mountain, dealer fixed it 2) I know the engine bay in my 'Lude is hot because the hood gets pretty warm but I never popped the hood on my car to cool it down. The engine has 191K and counting, got a chance to look at the inside of the head when replacing the exhaust cam cap seal, it was pristine, no oil sludge buildup. I am usually pretty punctual about oil changes (mostly Castrol 5W-30 dino juice, anywhere between 3-4K)

Since i installed Long Tube Headers on my truck, there is much less Heat Soak in the engine bay. I dont have header wrap, the stainless steel just cools off much faster than the stock manifolds. The block and heads are aluminum, so that helps too

There's a pretty steep hill I need to go up to get to my house, and I always have my foot in it pretty good going up it. As I get to the top, I let off the gas and try to coast as long as I can to get everything cooled off before I kill the engine once parked. I'll let it idle for a minute before I shut it down, too, on super-hot days. I run Amsoil in most of my vehicles, so I don't worry too much about internal heat. Things would have to be burning hot to coke up Amsoil Signature Series oil. My Silverado is past the point of me caring too much about it - been a lemon since even before it rolled off the showroom floor! At 102k miles now, so I figure I've got 30k more miles before the engine fails, either from a stuck AFM lifter, broken valve springs, walked cam bearings, or any number of the other failures this engine suffers. I definitely won't go above and beyond to keep heat out of it. The replacement engine will get better care than this one. If I had an engine like the Fairmont, I most certainly would open the hood! That's a giant aluminum bank account right there. 😁😜

I drive a ‘95 Jeep Grand Cherokee 4.0, and let me tell you that heat soak is very real with those old shitboxes. Never once happened in my old ‘98 Civic, and I had that thing for over 7 years. It’s a shame it fell apart with age.

I really don’t think this is an issue. If you are running a modern synthetic oil sitting in an engine that’s shut off it will be what maybe in the 212-217f range? Isn’t the cook off temp for synth something in the 400*+ range? This is a nonissue to me. Run a good oil and change it. Doubt doing this will solve anything. Now maybe if you come off a track or something sure... but you are changing your oil way more frequently anyway doing something that severe.

My owners manual for a 03 VW GLI says that after cruising on the highway, NOT to abruptly shut off the engine, but to let it run for a couple minutes to avoid "hot spotting" I assume certain parts become deferentially hotter, and having the water pump run allowed things to even out upon cooling
