Ok so ive got my cummins engine all torn apart in my garage and i have to leave the vette out. We do drive it daily and the owners manual says its right in front on the surge tank but I don't see it. Can someone specifically point it out to me. Thanks everyone.

 

You have a Cummins engine in your Corvette?

 

The Owner manual says:

Engine Coolant Heater
Your vehicle may be equipped with an engine coolant heater.

In very cold weather, 0°F (−18°C) or colder, the engine
coolant heater can help. You will get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
At temperatures above 32°F (0°C), use of the coolant
heater is not required. Your vehicle may also have an
internal thermostat in the plug end of the cord. This will
prevent operation of the engine coolant heater when the
temperature is at or above 0°F (−18°C) as noted on
the cord.
To Use The Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is located on the driver’s side
of the engine compartment, in front of the coolant
surge tank.
3. Plug it into a normal, grounded 110-volt AC outlet.

If you don't see an electric cord, then you don't have the heater.

I live in a cold climate in Eastern Canada, and I seldom if ever use a coolant heater, or a block heater in any of my winter vehicles.
My summer vehicle, the Corvette is stored in a heated garage during the winter months

The RPO code is K05 which should be on your Silver colored RPO code sticker inside your glove box. if you have a heater installed.
If not, you can buy an aftermarket in line coolant heater and install it into small 3/4" coolant line if you really want one.

Hope this helps

 

Lol. No I wish I had a cummins in my vette. I have a old 98 dodge 2500 with a 12v cummins. Hence the username (Garman = last name 12v = cummins engine) so the engine is all over the garage and the car has to stay in the below 0 temps.

I will look into the rpo number hopefully mine has it. The is for the response.

 

This doesn't sound logical, but just for information:

Back in the late 1980s I put block heaters in three of our cars:

Camaro V8
Taurus V6
Corolla I4

The heater would only be turned on overnight if the garage temp would be below freezing and I expected the car to be driven the next day.

Within a couple of years, all three cars had a head gasket failure. I stopped using heaters and switched to Mobil1, no more problems.

If only we knew why...

 

It is a rare option and would have to be special ordered...no dealer would order the block heater for a lot car. Unlikely to have it.
