    Question about bypass the heater core

    Yes, the weather is very good all year, although there is all kinds of weather here. Just 3 hours from where I am there are snow-covered mountains, but I don't live in or frequent those areas.

    Question about bypass the heater core

    I was thinking the same thing; the idea is to eliminate unnecessary hoses. The truck is in Colombia, 72º to 80+º all year.

    Question about bypass the heater core

    Question for the forum gurus: Is the method I've shown in the image valid for bypassing the heater core, or is it mandatory to interconnect the pump ends with a U-shaped hose? (07 Tahoe, stock Engine 5.3, RWD). I definitely don't need the heating at all so the idea is to eliminate the 3-way...

    2013 Tahoe, Help Needed.Engine quits after key release from start position.

    My bets are on a bad switch, bad ground or the anti-theft system going crazy but you definitely need a bi-directional scanner to find out.

    2007 yukon denali oil leak

    Lol, I've lost count of how many times I've shared this video here, but I know what it feels like, I'm almost going crazy trying to find the source of this leak. Other possible origins: valve covers, oil pressure sensor and an unlikely but not impossible cause, a hairline crack in the engine...

    2013 Chevy Tahoe 5.3 gas problem help!

    Check your vapor canister purge valve solenoid, if you find carbon pellets there go ahead and change the entire evap system at the same time: both solenoids and the vapor canister. When doing so you should blow out all the fuel lines with compressed air and if possible wash the gas tank. In the...

    Escalade dies after driving a while and comes to a stop

    Is possible, the pellets get into the entire engine, I found them in the intake manifold, the purge valve, the injectors (fragments) and in the fuel/vapor lines. In my case, the fuel pump took the brunt of it, additionally, if the purge valve is stuck, a vacuum leak is created that can cause...

    Summoning the geniuses of the forum: Problem accelerating from a stop / hill, engine stumble [updated]

    :beer: The cleaning helped a lot, at the moment the problem is fixed, it hasn't failed for 3 days. Sometimes has a rough idle, but I've already ordered the pump and it's on its way from Miami, buying it here in Colombia is a scam, the dealer charge me three times the price plus taxes and I'm...

    Summoning the geniuses of the forum: Problem accelerating from a stop / hill, engine stumble [updated]

    Quick update: The rain delayed me a bit but I finished the cleaning process, some injectors were dirty but nothing out of the ordinary, all working, new gaskets for everything; unfortunately the problem continues. Tomorrow I'm going to test the fuel pressure parked and driving.
