Many aftermarket hoods, especially for sports cars, make use of large cowls, ram air vents, and most commonly heat extractors on the sides of the hood. I'm a techie and we're always spending insane amounts of money to improve our computer cooling systems, as improved cooling directly correlates to higher stable processing speeds. But does this hold true for cars? I thought that most engine cooling systems were efficient enough to keep an ICE at optimal temperature in all normal conditions. Do these heat extractors actually provide any practical benefit? I'm specifically interested in the affec

It really depends on the design of the hood. As I discussed in this answer , the way heat extraction works is via the venturi principle. Only when there is a low pressure area above the hole in the hood will there be any extraction of air (and possibly heat). To directly answer your question, though, yes they do provide an amount of cooling by removing the air within the engine compartment, which can become quite hot during any kind of usage, whether traveling fast or slow. To substantiate what I'm getting at, I found a guy who measured temperatures associated with his '03 Mustang Cobra. Those who know what the 03-04 Cobras are made of should know these are absolutely solid car, awesomely built, worth tons of HP/TQ. Anyway, on to what he was talking about. He did measurements from different points of his vehicle (underhood and in the air box, as well as at the extractors). Here is what he reported: I also took time to measure another temperature, hood vent air temp. I clipped the senso

Temperature Guage doesn’t work, fan on motor runs, air conditioner doesn’t work when this happens and message says, “steering assist reduced, drive with caution.” Replaced temperature coolant sensor, still having problem.

I am trying to troubleshoot a 4runner with 135k miles, auto, 3.4 V6 California emissions. This is the freeze data: PID Description Value Units 0x02 Freeze frame DTC P0420 - 0x03 Fuel system status Closed-loop, using oxygen sensor feedback to determine fuel mix - 0x04 Calculated load value 34.12 % 0x05 Engine coolant temperature 197.6 F 0x06 Short term fuel % trim - Bank 1 0.78 % 0x07 Long term fuel % trim - Bank 1 3.91 % 0x0C Engine RPM 2287 RPM 0x0D Vehicle speed 68.97 MPH 0x0F Intake air temperature 95 F So far the front and back Ox sensor was replaced and the MAF cleaned to clear a P0171 co

Been a long day. Im not good at putting pictures on here. So ill try again. This is on my 89 year old moms ford explorer.its a 2012 she bought new. 3.5 engine. All work has been done at the local Ford dealer. 75k miles. I looked it over and decided to check the air filters and a few other things. I noticed the coolant looks pink, it should be orange. She has ever receipt from the dealer service. Its never had any work done involving coolant. Just tire rotation and oil changes. Sad to say she’s never even had them change the air filters. So im wondering why does the coolant look pink? 20260102_

Coworker has a 2008 Hyundai Accent, which has overheated repeatedly, consumes a lot of coolant, and barely runs. He wants me to assist with repairing the engine, if possible. I assume by now, the head is warped or cracked, but what I am trying to determine is if the engine block in this model is iron or aluminum. If it’s iron, this can probably be repaired. If it’s aluminum, the entire engine would need to be replaced, which is more work than I would want to do.
