Diagnosis needed on car trouble

Recommended Posts

My wife noticed the check engine light came on the other day abnormally but then went away after an ephemeral stint. But then she tells me she's seen the check oil light flash on and off a couple times too. This morning we drove through some colder weather into warmer weather and parked and we noticed steam (white) rising from the radiator while idling in park. I had her turn the car off and in a few minutes it went away. Temps on the gauges looked normal. 

What I believe to be steam coming out of the radiator doesn't necessarily mean anything but when combined with the other irregularities, it could be  The good news is it's not burning oil. But it is a concern and getting in to see my mechanic is not a speedy process.

Based on this limited info, what do you think is going on? Nothing to worry about? Get it checked? Get it checked immediately? The bad news is we have one and only one car.

The engine light on, then off would indicate the symptom(s) are gone. Depending on the code, if the problem has been corrected or no longer an issue after a certain number of ignition cycles, it will turn off. This is normal.

When you say oil light. Is it the change oil light, or the oil can that is illuminated red? If its the red one, that indicates low oil pressure. If this persists, I'd have it looked at.

A little bit of steam on the radiator is normal because it's hot. If there is moisture on it, it'll steam. Doesn't mean there is a leak.

I am going to pass on this exact post to my wife. She's the one who will schedule the appointment with my mechanic as we need a 100,000 mile check up.

I have a local mechanic who I trust.  Grew up with his kids, been in business for decades.  I think the third generation is running it now.

I would ask around for recommendations for a shop that is not a dealership and take it to them over taking to a dealership unless you are still under warranty.

I have a great mechanic I trust. I have 20 years trusting him and his father's work. That's the good news.  Only trouble is he's busy in the next town over and maybe not the cheapest. But his work has never, ever failed me.

...it's pretty hard to diagnose something that new even if it's right in front of me.  It's a computer driven process, and there are diagnostic codes that get stored in the memory as these events occur.  That's one of the reasons your dealership is probably the best place to start, and why they charge such outrageous labor rates.  If you think of your car like a Microsoft product, but with slightly  better production values in design and manufacturing, you're close to the truth.

The oil light flashing…  The oil could be low and you need to add NOW, before you damage the engine.  Years ago I was in a car of my friend and I notice the oil light flickering.  He told me; “I’m not worried there is lots of oil”.   A few minutes later, the engine bearings seized up and totaled his engine.

If the engine was cold, and the oil is too thick (the wrong oil for the winter) the oil pump may not be able to pump the pump enough oil into the engine and the light flickers.  That’s not good at all for the engine.   Or the oil pump could be failing, which would be rare.

Or the oil pressure sensor could be bad. 

The steam…   Hard to say…  it could be bad.   Or just a leaking hose.

The check engine light…   Get the code and see what happened.

If you are really unlucky, and all 3 things are related, that could be something real bad, like a blown head gasket, which is rare.   Anything leaking out and dripping on the garage floor?

What the fudge is an ODBII reader?!?? ;)

If you have to ask, you don't need one.    Your mechanic should have it.

Years ago I purchased an expensive ODB2 device that connects via Bluetooth to my Garmin Nuvi GPS in the car.  It’s kind of cool to see all of data in the GPS display when you drive.

I don’t use it much, but it is nice to have if needed.

My wife had a Verizon Hum installed on her Pilot, then she bought another vehicle and gave me the Pilot. The hum tells me more than I want to know about my vehicle. It would tell me if I had a problem with the engine and what the problem is. It also tells me if the voltage in the battery is getting low (usually tells me that when it’s too low to start the car.) Since my wife doesn’t drive anymore I drive her car and just use the Pilot to haul stuff or when I need 4WD.

And if the service engine light comes on, you should be taking it to a mechanic soon to have them look if it can wait or not.

Is the Hum worth it?

I'm better off taking it to the dealer once in a blue moon.

PROS

  • Easy setup.
  • Intuitive app interface.
  • Automatic maintenance checks and reminders.

CONS

  • Crucial services depend on cellular coverage.
  • Pricey.

Not on a Honda, might be good to have on a problematic car. The hum also keeps track off all kind of other stuff. If someone else installs the app they can see where the car is, how fast you are going, tire pressure. My wife had the app before she gave the car to me. I called it spyware, I don’t need to have her watching me electronically. It tells you when service is due, might be good for people that forget to service their vehicle. (My brother and it used to be my son)

...I bought a cheap code grabber about 7-8 years ago to work on my wife's Toyota.   I think it's already outdated. :(

ODBII hasn't really changed.  Should still pull the codes, the hardest part sometimes is finding a site that can interrupt the codes.

Yeah. It would be a waste of money on my car. Spyware!

The HUM also at one time, was known for frying ECMs.  No idea if they've really gotten that fixed or not.

I've got several different ODBII readers, but I am a tool whore.  The last one I bought just because it looked cooler than my others, doesn't do anything special that the others don't.  I have issues.  :(

Is the steam from your radiator coming from a specific place, like a pin hole might do?  Sometimes when you run an engine out of water, the temperature gauges read normal because there is no hot water at the sensor. (especially true in cold weather).

You need to get the codes read somewhere though because no one here stayed at a Holiday Inn Express last night and remote troubleshooting is always wrong except for the one right answer.

Oh no.  Bad news bears.  Car problems are the worst.
