I just changed my water pump, heater core, hoses, t-stat, added coolant filter and switched over to pink precharged antifreeze. When I plug in my block heater I hear an immediate sizziling coming from the heater element area. I have never noticed this before and being somewhat type A wanted to see if you experts believe this is normal?
I've never heard that from mine, even after it has been plugged in for hours. I'm wondering if the cord connection is loose and is arcing a little causing your "sizzle". I would look it over closely to make sure that's not the issue as it could be a fire hazard if it is.
Every thing looks good on the element end. Nice and tight anyway. I usually plug the truck in and walk away. So it could that it has always done that. I thought it was maybe the different antifreeze. Also, I started keeping my truck in the garage and thought maybe I started hearing it then, since it is more quite in the garage than outside.
If any of you read this and are going to plug your trucks in tonight, stick your head in the wheel well and listen for a few seconds and let me know if you hear yours doing this please. Thanks.
My block heater makes the same sound - kind of sounds like a teapot when its hot but not yet boiling.
i'm also running fleetcharge (the pink coolant you're probably talking about - its just regular old ethylene glycol with pre-dosed SCAs). and my block heater is brand new (i blew it out changing my coolant last year - long story), and i just soldered a new plug onto my block heater cord. ...so, with all components of my block heater/coolant setup being nearly new, i'd say the 'sizzling' is a normal sound.
...actually, i usually listen for it in the morning. i use a cheap timer to run my block heater for just 4 hours each night and some nights it doesnt turn on right. i can tell how warm/cold my ride into work will be by whether the block heater is making noise or not :-)
and yes, that marinco setup is nice. i can't figure out if its my cheap timer or maybe water getting into my extension cord/block heater cord junction causing corosion that leaves me cold in the mornings sometimes. i'm leaning toward the latter as some sandpaper on the heater cord prongs last week has had it heating pretty consistent recently...
Thanks for the feed back on the sizzle sound. I am going to clean up the element cord end as it is pretty rusty and dirty looking but seem like all is normal.
I always like to put that pic up once or so every winter. Always newbees that have not seen that and I like it because it is the cheapest "mod" there is! LOL
