Enjoying your videos. Old cars may drive me to drink. May consider bourbon as a cure. Maybe you could recommend a good brand. I knew nothing about Northstar Cadillacs. Never even considered myself a fan of the brand. But last summer I managed to buy a pair of the "tri-nines." Little did I know of their infamy. What "Bro Stone" calls the short "header bolts." LOLOLOL So my '97 DeVille D'elegance has had overheating/coolant loss issues. I had my longtime trustworthy mechanic replace the coolant tank that I ordered from GMPartsNow. Not sure if he checked/cleaned/blew out the line that goes underneath the big silver engine cover. I'll be checking this on my next day off. I may try to tackle the thermostat changeout under your tutelage. TYVM for the great videos. I subscribed.
I have a 03 deville with an overheating problem a weird heater problem where the driver side gets hot but the passenger side doesn't and I'm clearly not getting cool and all the way through the system because my top hose has very little water in it and stays squishy and never gets hard so the previous odor replaced the water pump I've replaced the thermostat I've checked the top middle line for blockage but the coolant was kind of nasty so I'm now flushing they got for your video that show the location of the pecock because I could not find it. But when you flush do you close the pecock or leave it open? Do you recommend a separate heater core flush also? I have heard that flushing the whole system can lodge particles in the core and cause problems with heater core blockage?
What mm nut does it take it off
Can you do the same procedure with a 99 Oldsmobile Aurora??
Have a 99 cadi devile its leaking in the middle under neath the car
Love this guy
What a refreshing auto repair video! I'm 71…my dad raised 5 kids as a mechanic…first…I salute and join you in your "appreciation " of auto engineers"… I've made a point of owning pickups no newer than 1985…confident I could fix anything that went wrong. I started having kids who, as they "grew up" wanted cars that held current staus with their friends. I warned them if they bought vehicles that, when the hood was raised, looked like a drunk plumber built it I would be unavailable for repairs. Of course my first 4 kids are girls/women so I tried to keep up as much as possible but as my colorful language grew in creativity and volume I realized why my mom tried to keep us kids away from the shop area when my dad was working on a friend's vehicle on his weekends away from his job in a shop.for whatever brainfart reason I recently acquired a 98 de Ville… your video on the cooling system kept me from parking my "caddy" in the deepest canyon of "hell" . And your "calm " ironic personality kept my cooling system from driving me over "the edge ", whatever that is…so I'm having a shot or two of Hornitos and diving in more relaxed and accepting of just another job. I'm subscribing and recommending your videos.. and there will be a 98 de Ville for sale soon.

So I read another guys post where he losing antifreeze on the middle bottom of the car and he said the fix was a bad thermostat. Now if the thermostat is near the air filter, why would antidreeze be leaking from the bottom. I just floored it because of poor engine performance due to bad coils and then I saw the car was overheating and when I looked on the bottom of the car it was leaking coolant.
Your motorad video is marked private. Can you make it public?
