Maybe another quick fix when you need one? Opinions

Read this whole thing before you respond, please.

As some of you know, I got a 91 350SDL that I brought back to cold Michigan and when it stayed overnight here, it wouldn't start.

The car has no block heater, one bad glow plug, and an old old battery.

Charging the battery got it started the first time after three glows and no additional cranking.

My plan is obviously: new battery, new GPs and a block heater once the car goes into my man-cave for extended work.

The 240D has a great block heater.

HOWEVER, my curiosity got piqued.

The radiator overflow tank is the only connection to the cooling system.

What if you filled the tank close to the top with antifreeze, and temporarily attached one of these little cup-sized immersion heater units, about 500 W, to slowly warm the coolant overnight?

I'm wondering if this would work as a temporary fix.

Anyone ever tried this?

I doubt it would do much because the tank is at the high point of the system and the heated fluid would tend to rise and stay in the tank. The heaters in the lower radiator hose work due to the natural circulation of the hot fluid rising.

Strel,
The battery is only about a year old. Look through the receipts. It was purchased in 2009 from Advance Auto Parts. In fact, I think, on the battery itself is a sticker indicating the month and year of purchase.

Try a house hold fan heater under the front of the car until the hood gets hot ~ 1/2 hr.

The house hold heaters put out 1500 watts max. a blanket over the hood or over the engine to keep the heat in would be benificial.

A heat gun would put out more heat than a hair dryier blowing down the intake. I have one form harbor freight, has 2 settings, higher of the 2 is 1100 watts.

or one of these.

Charlie,

I have thought of a heat gun and rigging something to hold it.
I have the 220,000 btu/hr version of the heater as well.


I've also wondered about the magnetic stick on block heaters. Anyone tried one and can describe the effects?

Rod,

Maybe it was 01 09 instead of 09 01. Either way, it discharged fast. I was surprised.

doesn't your vehicle have a block heater built in? all you need is a cord right?
either way, the heat does need to be low in the coolant circuit to circulate, and the magnetic heaters are usually in the 90-120watt range. they do very little.

dipstick

Do they still sell the heaters that you slip in the dipstick tube? I used that kind in my Chevy 305 (carbureator) when I lived in northern Illinois. Worked fine.

As already said, heat rises, won't work. A heat gun can get too hot and may melt plastic if not careful. A hair dryer is much safer.

Hi
I used to live in Chicago and just about every winter the temp would drop to minus 10 degrees or so for a few days.

What worked best for me was a plug in heater that was installed in the lower radiator hose. It was sold by JC Whitney. They also sold oil dipstick heaters. Both heaters were cheap to buy but I don't know if either is still being sold.

You have a block heater, you just need a cord if it doesn't have one.

Look up, behind the pass-side engine mount, for a "freeze plug" looking thing with a red plastic screw-on cap. Remove the cap and install the block heater cord.

Should be a 10-15 minute job if you have the zip-ties on-hand to run the cord to the tow-hook cover.

I've heard you can put an incandescent bulb, say, the one on your service light, under the hood and it will keep things warmer.

75 watts...
you could set a lightbulb under your hood and do more...
only thing this will do is SLIGHTLY thin your motor oil for easier starting... not gonna do anything unless you drive a lawn mower...
