No spring water, you need distilled sky juices.

 

Yes, distilled spring water.


Found my problem with hgih temp guage readings.
Temperature would rise and fall as running speed increased.
Bad (viscuos) clutch fan. Porsche mechanic could hold the fan blade with no resistance while engine turning. As the engine turning he could slowly bring the fan to a complete stop. He tried this after a hot run.
BTW I DONT RECCOMEND ANYONE DO THIS!!

 

Pharmacology - that was a former life. I worked in a hospital in a city where certain down-and-out types would drink antifreeze or use it as a mixer since it is sweet and intoxicating. About 5 ounces will kill an adult in about a week. Two ounces will kill a dog or child. The treatment for ingestion, once it is absorbed, is (or was 20 years ago) intravenous alcohol in sufficient quantity to occupy the dehydrogenase enzyme and prevent the glycol from being converted to oxalic acid. So, the patients would get a great buzz from the alcohol treatment for 4 or 5 days. Saved quite a few lives until the next time. The bad ones were the guys that mixed Sterno (methanol) with antifreeze. Can't recall what they called it, but that was real nasty stuff.

 

Bill,

According to the winos (sorry, I mean alcohol enabled persons), which type tasted better? The phosphate free type or the good old fashioned strong stuff? Inquiring minds want to know.

BimmerMike,
So did the reinvigorated vicious fan fix the fluctuating temp reading?
Was the coolant pump replaced at last timing belt change?

Think warm coolant readings at speed points towards inconsistent coolant flow
as moving air keeps the radiator cool without the fan pulling air through it.

Nasty coolant ingestion story I heard was some Grandma transporting grandkids
in her van. Kids saw a nice jug of lime-green stuff and drank some.
Looks just like Kool-Aid/Gator-Aid.
Don't know if that was true. But with the colors they color 'em cornsyrupy
kiddie drinks these days, wouldn't surprise me if there's lot more
household poisoning of kids these days.

Ernest (NYC) Capt'n Koolant. 4 coolant change in 2 years. Now with GL-5. Finally.

 

Ernest, new viscous fan not in yet and yes water pump was changed at last TB
At high speeds temp is normal, only at slow moving speed and idle would temp shoot up. Clutch fan not engaging to cool radiator.
Hope new clutch helps !

 

The problem on the drivers side of a RHD car is that the air injection? plumbing gets in the way of the socket wrench you need to undo the block plug. You simply can't get enough torque on a box wrench or similar. I wasn't able to undo this plug until after I'd removed the air pump and all it's plumbing. What's more when I got the block plug out I found that it did indeed have anti seize on the threads.

 

Paul, try it with headers... PITA. I just got the driver's side out, but that drains enough that I didn't bother with the other side after flushing.

I tried for hours at several points to break the plugs loose with heat, PBBlaster, Liquid Wrench, hammering, and many curse words. Finally I put some Kroil on one and a few mintues later it popped loose with a light tap (you know, the "Am I lined up to whack it?" tap) on the end of an 18" breaker bar.

 

My old Saab mechanic used to work at one of those giant multibrand auto malls. He said one day they were cleaning out the new fluids room and he looked at the antifreeze bottles... green, orange, blue, yellow, pink, purple, and red. They have the primary and secondary colors covered.

 

It's called "Squeeze" or "Torpedo Juice".

The movie Andromeda Strain has a good vignette with the old man explaining how he fixed his stomach pains.

Cheers,

 

Nobody addressed your core question. Ethylene glycol and propylene glycol are chemically very similar and can be mixed without harming the cooling system. Ethylene glycol does have better heat transfer properties than propylene glycol. Adding propylene glycol does not make the ethylene glycol less toxic. However, every article I've read from manufacturers specifically warn against mixing "orange with green." Personally, I've seen systems with a formation of gel in the radiator and other areas with less flow, and read somewhere that mixing Dexcool (orange) with green causes this.

Personally, I never mix colors - just not worth the risk.

 

Thanks JP

 

Viscous clutch fan....NEW, fixed alarming fluctuating temp readings.
