Did they originally cold weather test the LT5?

[rush91]

It's cold here in Southern Illinois...it probably hasn't gone above 10 degrees the past week. I haven't even started my Beast since around Thanksgiving, just sitting in storage on a cold concrete floor.....Today I decided I needed to go start it, maybe drive it around. My daily driver is a 2006 Honda Civic Si, which I bought brand new. I go to start the Honda, and it will hardly crank!!!! Now this Honda is as Bullet proof as the LT5, I've never had one issue in 145,000 miles and counting. But it's SO cold it takes me at least 7 tries for it to catch and finally start.......I get to my storage unit, take the cover off my Z, and see the temp gauge on the climate control says it's 7 degrees outside. On THE 1st try, no hesitation or anything, the Beast comes alive!!!!!! I was shocked, I thought it would at least be a weak crank or something. Amazing......once warmed up I drove it for about 2 hours, filled her up and put her away again.

Sorry for being so long winded, but I was just amazed at the reliability and durability of the LT5....Did GM ever cold weather test the LT5???? We all know of the records set out in the desert, but they must of knew this engine would be good for even an owner in cold climates.

I’ve seen pictures in The Heart of the Beast of cold weather testing.

If you look on the streets of NY you would swear they are all snow covered.....There all an off white color....Thing is its not snow, its salt.....When there is just a hint of snowfall in NY now they dump tons of salt on the roads...

Wouldn't even think of driving with all the salt on the roads..Bummer....

I'm also interested in winter start-up feedback, as I have to move the car next week to access an engine (454) that I sold. After a few single digit cold nights, will have a day of 46°, night before I'll place an incandescent drop light at the floor under the engine which should help warm it.
Streets around NYC area are excessively salted, the Z's wont be driven till the heavy spring rains wash it all away.

YES, the LT5 was cold tested - CANADA at -40*F. IIRC the cold start tests were described in the HOTB book.

I've see pictures of the cold testing of the test mules in Europe in the snow and ice.

IF YOU HAVE NEVER STARTED A COLD!!!! LT-5 THEN;
Follow this procedure carefully to start an LT-5 that has been sitting in zero degree weather.
Do EXACTLY as instructed!!!


1- open door
2- sit in driver's seat
3- depress clutch pedal
4- insert key into ignition
5- turn key
6- release key when engine fires up almost immediately.
7- smile broadly


Happy New Year!!!

Lol...good answer. That’s why cold weather testing is done, so we do precisely that.

The only problem I have had with starting when it is cold is that the tires don't have much traction at 10 degrees F. Other than that the ZR-1 runs great.

That and the LT-5 loves the cold air.

[Paul Workman]

Oooh! YES is does!

Testimony to the fact it is starving for AIR in the stock form.

The car was built in Bowling Green, but is from The Great Lakes State of Michigan! We have COLD weather five months out of the year. They're all cold weather tested! :-)

Since I hadn't driven it in over a month, I had never experience flat spotted tires......OMG!!!! It felt like I had square tires for about 5 miles lol!!!

I was just amazed at how after sitting in minus degree weather, it started like it was a summer day. These engines are incredible.

I am a little surprised by this Thread. I guess because for us we wouldn't think about driving our ZR-1's in major snow or cold, but back in the day a lot of Vette owners drove them as their only vehicle. I worked one winter in a very snowy area of Ontario (Owen Sound). Two of our guys had C3's (the current generation at that time). They slapped four snow tires on their cars and went pretty much everywhere with them. I would think that every car built in North America is built to withstand cold weather.

Installed Odyssey pc925 battery with adapters and disconnect (neg-)

Weather today warmed up to 48°F, after a few weeks of freezing temps and single digit nights. So, I tried Marty's method and the car started right up, after months of hibernation. No chain rattle, tapping, injector knocking, or any odd noises.
