    coolant leak passenger rear of L59 engine

    That was the first thing I looked at. First I felt them (dry) and then I looked at them from the underside with my mirror, after I thought about using it. That is not the source this time around, although I used to drive another GMT800 for work and I did see that problem on that one.

    coolant leak passenger rear of L59 engine

    Ok small stain of coolant under general area of starter. I can see it's dripping off the rear of the motor. I traced it up to the head from underneath. Using a mirror on a stick, I inspected the rear of the head around the freeze plug and it is dry around the plug, but wet on the ledge where...

    HVAC problem

    Posting because it's happening more often lately. Every once in awhile, the HVAC will go full hot out the vents. Usually this is when AC is selected, but I think it has happened once when heat was already selected. When it happens, the control panel doesn't respond to any inputs. Shutting...

    Wife overheated the 2005. . .

    Another update. I've heat cycled it three times now. Lost some coolant level after the first one, but I expected that, happens every time you reload the cooling system in my experience. And I did lose about the amount I expected. The second two times, I didn't lose any level. So far so...

    Wife overheated the 2005. . .

    Another update: I got it put back together. Napa didn't have the non-oil cooler radiator in stock, so if this thing survives this escapade, I have the option of installing the oil cooler lines in the future I guess. Radiator is ready for it lol. I filled it up with coolant, fixed trans fluid...

    Not a bad idea. And it's right there. I'll pick one of those up as soon as the store opens and I determine if they have a radiator for me.

    Wife overheated the 2005. . .

    Update: Radiator side tank has a three inch long crack on the left side below the upper radiator hose connection. There was some coolant left in the radiator. Not sure about the engine. So I'm going to do the obvious thing and replace the radiator since I got it out in about a half hour...

    Wife overheated the 2005. . .

    5.3 Engine is about 5 months old. Professionally installed Jasper engine with a warranty. I do not know how long she ran it hot, because she wasn't watching the temperature gauge. She did say it was pegged when she finally looked at it. I do know that when I arrived, the drain plug was...

    Hate to do it but I did search first -- oil consumption

    I do have oil on ground. I believe most of that is coming from the hydrobooster though (and I am losing a requisite amount of power steering fluid, which I replenish). The hydrobooster has a leak by what I believe to be an accumulator. I'm sure the engine leaks some oil too, just not all...

    Hate to do it but I did search first -- oil consumption

    Engine is a 5.3, in a 2005 Z71 suburban, original to the truck as far as I know. It now has 219744 miles. Consumption is a small bit more than 1/2 quart per 1000 miles. Lots of freeway usage on this particular oil change (we are 1000 miles in). I change the oil in this truck every 3000...

    Had a lifter temporarily get stuck. . .

    Well, to answer several of the above points. Most important, the engine has not made this noise since then, over several hundred miles, so that is good. I have had the valve covers off this engine -- it is quite clean inside with no sludge visible anywhere. So I'm not suspecting dirty as...

    I have had the valve covers off within the last ten thousand miles. This engine is actually really clean under there. Sent from my iPhone using Tapatalk

    In case it is Germaine to the discussion then, I have never run it on anything besides regular unleaded. Sent from my iPhone using Tapatalk

    Do you mean that cylihder deactivation? I don't think so. And it is not a flex fuel motor either, I don't think. I guess I don't know what AFM means. I only know the term in reference to older Bosch fuel injection cars, which have an Air Flow Meter, or AFM lol. And I know this truck has an...

    Had a lifter temporarily get stuck. . .

    Engine has 216k miles, is a 5.3 L59. Has had oil changes regularly between 3 and 4.5k miles at least since 143.5k miles, when I acquired the truck. It happened while the engine was idling in a fast food lane, and I was able to get it unstuck after leaving the fast food place. But . . . I'm...
