Block Heater

Does anyone have the engine block heater installed? It takes miles to start getting heat in our car. My wife will warm it up for 10 minutes and the heat is barely warm with temp gauge above the 160 degree mark. She has to drive a couple of miles after a 10 minute warm up to start getting good heat. The temp was 16 degrees this morning with a steady 30+ mph wind, so it was cold. I wonder if its more cost effective to have the block heater plugged in and a 5 min. warm up and get heat faster. I had one in my Suburban and right after I unplugged it the defrost would be a little warm on start up.

Re: Block Heater

The block heater will not begin heating until the outside temp is below 0F or -18C. It is alot colder than that where we live. I am a real believer in using the block heater for about a 3 hour period to reduce engine wear. I wish that the block heater would function when the temp is below 10C.

Re: Block Heater

My understanding is that on cold weathers, when a car is equipped with engine block heater, there is a power cord that needs to be plugged in, either overnight or right before starting the car, to a power supply, in order to warm the engine or coolant for ease of starting. I had it in my 06 Trailblazer and my 2010 Traverse. However, even being here in Toronto, Canada, where the weather is really cold during winter months and lots of snow, I haven't even used this feature yet. My friend, ont he other hand, told me, that feature was very useful to him when he was in Alaska.

Re: Block Heater

The power cord by the way should be anywhere under the hood near the front or headlights which you can pull out. I haven't seen it in the Traverse yet, coz I haven't pick up yet.

Re: Block Heater

hey red- if you still have your Trailblazer... you may want to check out trailvoy.com
I hang out over there--- all you want to know about Trailblazers, Envoys, and the other GMT-360's.

I remember reading over on the trailblazer forum- that some members who had the block heaters- Not sure if they had aftermarket or factory....but they would use those timers that you can plug in-- and set it to come on at x hours before they were to head out.......

Re: Block Heater

When making the factory purchase of our Traverse this past spring I had intended to include the option of a block heater in the configuration but to make a long story short it got left off the order.

It is easier to add an oil pan heater rather than a block heater. Depending on the model they secure via magnet or silicone adhesive.

Re: Block Heater

Applying a bag of ice to the plug end will not be cold enough to close the circuit switch in the thermostat plug end. The ice will only get down to 32 F, and the switch closes at 0 F. With regards to replacing the thermostat plug with a regular plug, there have been posts that have explained that allowing the block heater to run at outside temps above 0 F will cause the system to throw error codes. GM designed the system for a reason, and the reason probably was not to save power. I'm thinking that the block heater element is possibly placed in a close proximity to an engine computer temperature sending unit. Maybe one of our tech members can explain.

Re: Block Heater

Since the temp sensor is in the plug end, I would also make sure that it is out of the engine compartment to sense the ambient temp outside, as opposed to being left under the hood sensing the engine compartment temp which is probably much warmer than ambient for a little while.

Re: Block Heater

I called my dealer yesterday and they said the heater is set to maintain a certain coolant temp. They claim it will run if its 30 or 0 outside. As long as the coolant is colder than the heating element it will warm it to whatever temp its set for. I was reconsidering having it added if it won't work above zero. Does the end of the plug look like a standard plug or does it look like something larger?
