Scotty Kilmer, mechanic for the last 49 years, shows how you can fix your overheating car.
replace the radiator and PRAY the head gasket isn't blowing. for that, do this video test https://www.youtube.com/watch?v=QA7KVQq9vKA
Hi Scotty, I have a 1989 Honda Accord with an overheating issue. But it only overheats when I am going over 60 mph. If I drop below that it cools right down. When I am below 60 I can see the temperature rise and then the thermostat open and the temp drops. So I think the thermostat is working. But when I am over 60 the temperature will rise then I can see it pause for a bit then rise again. If I turn the heat on it will immediately drop to about 3/4 and stay there. When I am going below 60 it will stay below 1/2 on the gauge. Any idea's? Thanks in advance, Chris (Tofer)
you never know, I had a customer that lasted over 3 years in. But if you really want to keep it, get one of those 3 year motors
Hi Scotty, I have watched a lot of your car repair videos on Youtube. I just bought a '94 g20 van with 121K miles on it, 350. I suspect it got hot at some point because the oil filter was virtually baked on when I changed the oil. I saw your video on using "Steel Seal". I changed the plugs and non were wet. I pulled the thermostat and it was bad. Radiator cap was bad. Now i'm flushing the cooling system with radiator flush and a few rinses as per steel seal instructions. No thermostat in now. Radiator appears to be working and passed pressure test to 40 lbs. with no leak down. No leak around water pump. But, i get steam and water dripping from the tailpipe. No oil in the water and no water in the oil. The van runs well. How long should I expect the Steel Seal to work? My mechanic says "You don't want to put a new motor in that old van." I'm poor and I need a good running van. My thoughts are I could have spent $10K on a used van and still have issues like this so I bought an older one for $2K. It is rust free. What are your thoughts? Just use it until it blows up or try to sell it (i'd hate to do that although it was done to me) or replace the motor with one of those from AutoZone or O Reilly's with the 3 year unlimited warranty? It's a conversion van and I can do some work and I want to go camping in it like van dwellers on youtube. Thanks in advance, Garth
