radiator
"And it ended up on our doorstep because as it wheezed into the tri-state area, the radiator let loose, kaboom. And it was just coolant all over the place. So I said, you know, we've got to find out where, why, you know, for a radiator to fail like that, I won't say is abnormal, but it's not a common thing. ... But we had to put a radiator in it. The radiator was confirmed, the radiator was bad. It had, it was leaking. There was a crack or some sort of a leak on the driver's side."
A radiator is like a car's air conditioner for the engine. It cools down the hot liquid that goes through the engine so the engine doesn't get too hot and break.
The radiator is a key component of a car's cooling system that dissipates heat from the engine coolant to prevent overheating. It circulates coolant through the engine and then cools it by passing it through a series of thin tubes exposed to air.

oil viscosity
"Sure. Yeah, I've heard you to great find that the viscosity in the oil that they're recommending in, like my raves, zero to 16 is really not doing well for these engines."
Oil viscosity means how thick or thin the engine oil is. Thin oil flows easily when cold, helping the engine start, while thicker oil protects better when the engine is hot.
Oil viscosity refers to the thickness or resistance to flow of engine oil. It affects how well the oil lubricates engine parts at different temperatures, with lower viscosity oils flowing easier in cold conditions and higher viscosity oils providing better protection at higher temperatures.
0W-16 oil
"Yeah, I've heard you to great find that the viscosity in the oil that they're recommending in, like my raves, zero to 16 is really not doing well for these engines."
0W-16 oil is a very thin engine oil that helps the car start easily in cold weather and can save fuel. But some engines might not work well with oil this thin.
0W-16 is a very low viscosity engine oil designed for improved fuel efficiency and easier cold starts. However, some engines may not perform well with such thin oil, especially under higher temperature or load conditions.
start-stop vehicle
"Are you a start stop vehicle? It is, but I don't use it. OK."
A start-stop vehicle turns off the engine when you stop the car to save gas and then starts it again when you want to go.
A start-stop vehicle automatically shuts off the engine when the car is stopped (e.g., at traffic lights) and restarts it when the driver releases the brake or engages the accelerator. This system improves fuel efficiency and reduces emissions.
oil change interval
"Do I think that that oil change scenario as far as interval matches? No, I'll defend that to my die in day. ... short trips, longer oil change intervals, and or now combined poor quality filters, wrong viscosity."
Oil change interval means how often you need to change your car's oil. Changing it too late can hurt the engine, especially if you drive short trips or use bad oil.
Oil change interval refers to how often the engine oil should be replaced to maintain engine health. Longer intervals can be risky if combined with short trips, poor quality filters, or incorrect oil viscosity.
oil filter quality
"short trips, longer oil change intervals, and or now combined poor quality filters, wrong viscosity."
The oil filter cleans the oil in your car. If the filter is bad, dirty stuff can hurt the engine.
Oil filters remove contaminants from engine oil to protect the engine. Poor quality filters may fail to adequately clean the oil, leading to increased engine wear.
fuel trim
"And the fuel trims were now positive. I'm sorry. Fuel terms are negative at idle and going positive under acceleration."
Fuel trim is how your car's computer changes the amount of fuel it uses to keep the engine running smoothly. If it adds fuel, that's positive; if it uses less, that's negative.
Fuel trim refers to the adjustments made by a car's engine control unit (ECU) to the fuel injection system to maintain the optimal air-fuel ratio for efficient combustion. Positive fuel trim means the ECU is adding more fuel, while negative means it is reducing fuel.
throttle body relearn
"I relearned the throttle body after I cleaned it. All right."
When the throttle body is cleaned, the car's computer needs to relearn how the throttle opens and closes so the engine runs right.
Throttle body relearn is a procedure where the car's ECU recalibrates the throttle body's position sensor after cleaning or replacement to ensure proper idle and throttle response.
fuel system cleaning
"I would definitely do some sort of a fuel system cleaning beyond the throttle body. So I sent him home with a prescription for a CRC one tank."
Cleaning the fuel system helps get rid of dirt and buildup inside the parts that deliver fuel to the engine, so the car runs better.
Fuel system cleaning is a maintenance process that removes deposits from the fuel injectors, intake valves, and combustion chambers to improve engine performance and efficiency.
CRC
"So I sent him home with a prescription for a CRC one tank."
