The drain fitting is always a hassle to get to. From up top I use a long screwdriver and tap the wingnut loose. Then reaching from underneath open the drain valve. Coolant goes everywhere. I like the orange prestone. One jug then finish with a gallon of distilled water. With new radiator and thermostat my engine never over heats. Installed two years ago at 240,000 miles. Old radiator wasn't even leaking . I still got it. I live near New Orleans and in June I'll head to San Francisco for a month. G-20s RULE !
Limping home with a known cooling issue, best thing is to turn on the interior heat and monitor for continual warmth. No warmth = low coolant. Most vehicles will first sacrifice cabin heat for engine protection. Monitoring that in conjunction with the engine temperature sensor reading is the ultra indicator for dangerously low coolant awareness. I've done the same thing. Great VIDEO! (I learned where my radiator drain is physically located). Just subscribed 👍
Thanks for showing us, I'm downunder in Australia, I shipped my '93 GMC Vandura conversion van to here, its only done 50,000 miles. This week it started a leak from the top of the core. Like you I have to work in my driveway. Luckily these vans will let me squeeze under them. I notice that you removed the fan assembly, at what stage was that and why? Can I buy these radiators from Amazon? Would you know the part numbers for the hoses and the belt as this will be a good time to swap them as you suggested? Why did you remove the dog box inside the van? On the temperature guage what is the usual running mark when hot? Mine cruises at the 1/4 mark, is that normal? Thanks for your help, -Rob Mornington Australia.
Hi, I got 1990 6.2 diesel G20 Chevy van and I have problem I need new radiator but I don't find right part (old one is iron). I only fing gasoline radiator that look like your's radiator will that fit in my Chevy or is the transmission and engine oil cooling line different.😅 Thanks for already answered. Greetings from Finland
I have no idea my friend. You'll have to compare the dimensions on the stock one to the specs given by the manufacturer of the new one. Not all 4 row designs will be the same fit.
I got the geneva, shes a tough ole gal, 350 pushing just over 250,000 and she purs like a kitten, i love my van, does everything imaginable, vans may not look sexy but damn it they sure can fuxx, lol, on another note gas is killing me rn in that big truck!!!
