where do I point IT?


Recommended Posts

Dumb questions of the day courtesy of your local FAQ Board numb nut:

I just got an infrared thermometer (cheap at harbor freight) to more accurately diagnose my overheating problem.

Where, exactly, do I point the laser to get the relevant reading? (Radiator hose? Block? Top of radiator? All of the above?) BTW, If some one says something like "up your ass" we might have to go to blows... HA!

What is the temperature reading I'm supposed to get? I believe there is a 71deg thermostat in it, if that makes a difference.

What temps should make me really worry?

I'd love someone provide something like this (I'm obviously making up the ranges as I have no idea!):

150-170 cool

170-180 optimal

180-200 warm

200-210 hot

over 210 defcon 5

And final dumb question o' the day: What is the coolant to H2O ratio that seems to work best?

Thanks to all who are willing to help!

Point it @ the Temp sender housing right after you shut down should be as accurate a reading as the "Lazer" can provide. Hoses are insulated and the radiator is, well, a radiator it is supposed to be cooler. The T-Stat will tell you what degree it is as it is stamped right on the housing.

But you really need to answer a few questions like how old is the Radiator, is it weeping, is it a 2 row or 3 row if you have a tii, are there any other leaks, what is your timing situation, are you backfiring on decel, do you have a bad ground on your temp gage and or your VDO sender, just to name a few.


But what do I know

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
