1995 Chevy Cheyenne 454/7,4L. I have a bad oil leak, when I checked the oil pan bolts one or two slightly loose Drained oil & oil filter was loose, Took off with my hand.

I have a 2000 Sierra 1500 4WD with a 5.3L Chirping at

Hi. I have a 2000 Sierra 1500 4WD with a 5.3L Chirping at crankshaft RPM with both belts removed. It's loud at the bell housing and also very notiicable atop the engine - driver's side rear. If it were cam related, it would be at half-crankshaft RPM though, no?JA: Which belt is acting up? And when was it last changed?Customer: It's not a belt problem The chirp persists with both belts removed.JA: Are you fixing your Sierra 1500 yourself? What have you tried so far?Customer: I've simply eliminated any accessory making the noise and trying to diagnose so I can take either to a mechanic or a transmission shop. I've read a variety of articles about "chirp" noise related causes.JA: Anything else you want the mechanic to know before I connect you?Customer: That's it - thank you.

I have a 08 Chevy Equinox, 3.4 engine, AWD. Last

I have a 08 Chevy Equinox, 3.4 engine, AWD. Last Thanksgiving 2016, my wife said the heater in her car wasn't working right. I checked and found that it blows warm air then changes to cold air, goes back and forth no matter where it is set on the controls. I have done the following:JA: Have you checked to make sure the thermostat is working? What about the coolant level?Customer: 1. Blowed the lines out to see if there was any blockages. 2-3 times for this. 2. Changed out the heater core. 3. The blend motor was changed out while it was tore down to change the heater core. 4. I changed out the water pump for the second time as I found it was leaking a little bit. 5. Last I changed out the blower motor resistor. To answer your question, both are fine. The heater hoses are so hot you can't hang onto them.JA: Are you fixing your Equinox yourself? What have you tried so far?Customer: I have been reading online with several sights the heater problem I am having is a common issue, but no one seems to say how they fixed their problems. Yes I am the owner of a mechanic shop and this has me stopped. I haven't found out how to fix the problem yet.JA: Anything else you want the mechanic to know before I connect you?Customer: I just need an answer on how to fix this problem which seems to occur in a lot of cars like mine.
