So it was 13 degrees on the way home from work today. Jeep sat outside in the cold all day, as I am pulling in my garage when I get home I shut off the radio (engine still running) and can hear a clanging noise from the engine. Not as loud as knocking but a noise none the less. Shut off the Jeep and will have to see if it does it again when I start it in the AM. Any ideas?

 

I have the same noise when it's minus 10 celsius

 

Ever figure out what it is?

 

I really have no idea!

 

Single digits here to, last night when I started my Jeep it made a weird sound, don't know WTF it was.

 

It's minus 30 celsius this morning

I used the bloc heater for the very first time, and did not heard this strange noise

 

Whats odd is mine was doing it after driving it all the way home when the engine had already heated up. 5 degrees this morning, this should be interesting.

 

Mine sat at the airport since monday and when I started it this morning it warmed to a -11 degrees, it was -16 overnight.

Anyway it made all kinds of new noises I have never heard of before, but they all went away very quickly. Clutch squeeled, a tick at start, noisy power steeriing.

But after a short time ideling and driving in first gear at idle thru the parking lot all was well..

 

It was -2 here this morning and it make a noise at start up. After start up it sounded normal for my entire drive to work though.

I think it would probably be normal for a super cold start like that, Im not 100% sure on that though. I would imagine it is harder on them.

 

I have some noises when temps are below 30F.

1: Valvetrain noise, it's quite loud when I fire it up right away in the morning, and goes away after a short time. That length of time gets longer the colder it is.

2: Power steering squeal. This goes away almost immediately after startup.


The valvetrain noise is quite concerning, and I'm now exploring getting an oil pressure gauge.
