I live in St Louis and work at Indianapolis as a manufacturing engineering for aircraft engine manufacturer. I have a history of working with cars, however at 59 I try not to. Oh, joys where ’66 SS Malibu and a 71’ Z28 (and yes a wish I still had them). Use to cam them, add big carbs, tires etc… they were good days.
On March 31, 2013, - (1 am) west of Effingham Ill in route to Indianapolis (Hwy 70 – speed 70mph) broken timing belt. Note: temp in 50’s F. Towed to Effingham Ill by AAA.
3-31-2013: Water pump, idler, tension arm, belt and plastic cover (broken by belt).
Cost with labor $780.00. Given one year warranty. Shop was not my local, but a Effingham location (about 150K miles).
2-28-2014: same shop replaced accessory drive belt and relocated bottom pulley (170K miles).
Squealing (Howling) sound (like a rub) occurring during single digit temperatures of winter 2014. Can hear moderately loud squeal, with hood, doors, windows all closed sitting in car with vent fan running. The sound is not the fan. Concern is belt rub and failure; 2014 winter has been too long, too cold.
Taken to my local shop; they stated the sound seemed to be coming from within the timing belt cover and cost would be $600.00+ to go into (temp was about 10 degrees). I returned the car to Effingham repair shop and the temperature was 35 F+ on a sunny day… felt like spring. And of course no sound; they examined it and found that the accessories pulley (bottom) was not all the way on (about 1 groove out). The accessory drive belt had started to fray. They relocated the pulley, replaced the belt and apologized; charge $0.00.
Now 8 degree morning, and it’s back to haunt me. Squealing described above. I started at 1 am at 8 degrees in St Louis and 250 miles later in Indy the squeal was still there. Note squeals only at idle (750 RPM), increase to 1000 RPM and it goes away, so during highway travel it is not squealing. That same day, by noon we had 17 degrees and no squeal.
What is the most likely cause? Is it idler, tension arm, miss located or over tightened plastic cover? Or even a thermo reduced plastic cover rubbing at single digits only… similar to a car horn contacts sounding on a very cold day? Is this something damaged and failure is only a matter of time? Possibly it is just an annoying squeal caused by vibration at 750 RPM? It doesn’t seem to be an accessory bearing, as a stethoscope seems to lead me to the cover, however best judgment is difficult at night at single digit temperatures.
The biggest problem is how can I resolve this on a warm sunny day when I am not freezing my %#$@* off. Dangerous thoughts were (past tense) reduce the engine parts temperature by dry ice or a co2 fire extinguisher. Bad deal… requires very vented work area; gloves and eye protection and where exactly would I spray it. Do know any drive in meat lockers?
have the same problem?
