Steam on the inside of the windshield, 2002 GMC Sonoma 4wd 4dr 4.3L V-6, time for a heater core, radiator too. Where can I find step by step R&R heater core?
Same road trip, rear differential filled up with water, burned wheel bearing and axle shaft. Never in deep water. Just deep ___t .


Please Mr Mechanic, change the water in my rear end.

WOW !!! I watched some of the part one video... I would suggest going out to buy a box of zip lock baggies and a sharpy marker. Bag and tag all your screws and parts as you tear into your interior

 

Thanks Guys,
I'll look at those videos.
Last time I did one of these (pre-YouTube) I found a step by step written list somewhere online. I'd still love to find one. Seems quicker to me???

 

Before you tear the dash out of the car I would check the heater hoses first to make sure you don't a small cut in one of them that expands under pressure. I know that on the Sonoma Vans it's only a plastic cover concealing the heater core under the passenger side of the dash.
