    I did engine radiator replacement yesterday. I was able to do it without disconnecting any hoses or lines from other radiators. The trick is to raise the front of the vehicle, remove both lower radiator support brackets and upper ones, screws that hold radiators and fan assemblies together, temp sensor wires etc and then slowly, progressively move engine radiator down while keeping the rest of components up. It does not simply drop because of interference with other components. It still takes time but then there is no need to mess with other cooling systems.

    BLUF: REMOVE LOWER RADIATOR SUPPORT BRACKETS! Thanks for the advice! I replaced my main radiator two weeks ago, was leaking like a sieve, overheat CEL, etc. I followed your lead pretty well until trying to actually remove the radiator. As you demonstrated, the catches make it nearly impossible without uncharging the AC, draining the transmission even after cutting off a few of the support catches with an oscillating tool. Frustrated, I read the comments more closely about the removing two lower support brackets. They stick out like horns from the frame underneath the radiator sandwich holding up the fan and all the radiators with 3 bolts on either side. That's the move and the main radiator wiggled right out with some encouragement (bending/stretching). I built a little support jig out of 2x to support the AC/transmission/Battery radiator which seemed to mostly keep everything in place. Still lots of negotiating to get it out and more negotiating to get the new one in. I removed the battery radiator after all - helps to have the room. Reassembly was way easier. I simply filled, very slowly the three reservoirs, loosened the top radiator hoses to let some air out as I filled. Then ran the car and topped off a small amount. I had a P00B7 code that wouldn't clear with my OBD scan s/w, but cleared on it's own after about two days of driving. Also, changed oil. It was a not fun nine hour job, but better than redistributing my wealth to the stealership north of $1800 for a $130 part.

    I've done this repair. I did not need to remove the driver side headlight, the passenger wheel well cover, or the black metal bracket connected to the cross beam. I did not disconnect anything from the fan shroud. I had the ac discharged and disconnected the lines to the condenser. I drained the transmission fluid and disconnected the lines to the cooler bypass valve (silver box) left it bolted to the assembly. I unbolted the shroud and the front radiator. Removed the front radiator, unhooked the shroud from the rest of the assembly and lifted the assembly out raising the drivers side first. I left the shroud where it was.

And then, it took another two hours to lower the car after the work was done. That was a pain in the ass to do. After doing that, I purchased the 4 post car lift and became a happy DIYer.

    Great video! How many miles did you have before you had the engine leak? Were you getting P00B7 error code and did the engine overheat warning come on? I have a 2012 Volt with 75K miles that has been maintained well and am surprised the dealer just told me it will be $2K to do the job you did in your video. Is it unusual for a radiator to develop a serious leak in only 75K miles? Is there an additive to stop radiator leaks I should try before shelling out $2K? I live in cold and hot temps in the mountains, so I need it to be reliable.

    • @mjspiess
      @mjspiess  ปีที่แล้ว

      Thank you! I think it had around 140k miles. I only paid $2,900 for it knowing it had a leak and planned to flip it. I don't recall what code/s it threw, but the guy I bought it from told me the engine overheat warning did come on, he pulled it over and had it towed. Added coolant and then noticed it leaking and listed it for sale once he got the $2k quote to replace the radiator. This particular Volt only leaked if the engine was used and the radiator got pressurized, otherwise it ran on the HV battery flawlessly. There are additives to stop radiator leaks, but it's not recommended because it can cause the heater core to clog and gum up smaller coolant passages. It is a very difficult repair, so at a dealership this is going to cost a lot in labor.

      The coolant system pressurizes as it heats up, so there's not much of a good temporary patch option as things expand a bit. The hardest part is things typically need to be dry to apply anything external. I know JB weld has been used with decent success by others. The battery cooling radiator is the front one though and waaay easier to replace than the engine radiator in this video. If it's leaking from the front radiator, I would just replace it.

    Hey, I have a question about the Chevy Volt coolant leak issue. My volt is leaking coolant almost like a super soaker when the radiator fans start running. I've changed my water pump, thermostat n sensor, and even replaced the valve cover gasket. It almost immediately runs hot STILL and I haven't had proper heat or air at the start of these issues. Could this be like an easy fix, ie: a coolant tank replacement? I noticed the little latch on the plastic tank that stops the cap is worn completely off. And I had to replace my last tank cap because it pretty much exploded and got stuck in the tank. Also is there an easy way to flush clogs from the engine coolant line? Please and Thanks

    • @mjspiess
      @mjspiess  3 ปีที่แล้ว +1

      Are you able to locate the leak? Is it squirting and then the air from the fans blow it everywhere? Running hot almost immediately leads me to believe you may have a blown head gasket. If you don't have a compression tester, some other things you can inspect is white smoke from the tailpipe, air bubbles in the coolant tank and milky residue under the oil fill cap and/or on the dipstick. However, air in the coolant system will make it seem like it's running hot too and also not allow proper heat and the car probably won't allow you to run A/C if it thinks it's overheating. Without the proper vacuum fill procedure, it can take days or even weeks to fully burp the system, but with a leak, you'll likely never get it properly burped. It sounds like you're getting excessive pressure in your coolant system to make your coolant cap explode?! You'd have to use a garden hose to try to flush a clog from the engine coolant line, but these Volts are pretty sensitive to the coolant used, so you'd want to flush just the engine side in this fashion. I would start with a compression test though, check each cylinder and see if you have a head gasket leak and go from there.

I can't see the leak, but it is as you say, squirting and then the fans spray it all over. I feel like there is definitely air in the line. There's a whistling sound from the top coolant tank if I tighten the cap too much when the engine heats up, and upon cool down, the "area" behind the fans makes a squeal like air being let out of a balloon. Also, if it's worth mentioning, when changing the thermostat, I noticed a glittery, almost clay-like substance that looks alot like some kind of "quick seal". That's why I was asking about the flushing something out of the radiator. The car only starts overheating when the engine activates, so that's the line I'm worried about now.

The engine side is no where near as sensitive to burping as the electrical side, so you could burp the engine side like any other car. Drive it on ramps, jack up the front end or simply park it on a decline at the end of your driveway or something similar and let it run while adding coolant, but I don't think you'll get anywhere while the engine radiator is still leaking. I think I would still run a compression test to make sure you don't have a head gasket leak too. The coolant tank cap should be on as tight as it goes without any issues. I don't think the dealership will want to or maybe refuse to do a coolant flush before the radiator leak is addressed, but if you have a head gasket leak, there's no sense in doing either until the head gasket is addressed. You can get a cheap compression tester kit at Harbor Freight. I'd start there and rule out the worst case scenario first. If the compression is good, then get the radiator replaced.

      @mjspiess  3 ปีที่แล้ว +3

      Yes, it would be easier if you first took out the front radiator first. Exactly! I was also trying to avoid refilling the AC & transmission as well. I found one example from a Facebook group where the guy discovered if you remove both lower main radiator support brackets, you are able to remove JUST the main radiator leaving the front radiator, transmission cooler & AC condenser in place. I was surprised, but the pictures didn't lie lol!
      I'm hopeful I never have to do this repair again, but if I do, I will try that method of removing the two lower radiator support brackets to see if it's that much easier. I think it's 3-5 more bolts on each side, but gives you a LOT more space to drop the radiator.

    Good video. It is an ugly job. But I think I did it an easier way. I didn’t remove the headlight or fender well. I started top down and removed the front fascia. I didn’t break into the HV battery cooling system. I removed the AC condenser, and I removed the radiator support brackets, which allowed me to pull the radiator out the bottom. Time between AC radiator coming out, radiator out and back in, and AC condenser back in was less than 30 minutes. That is not how the factory shop manual does it. I didn’t want to break into the HV cooling because I didn’t have the tools to properly refill the system. It needs to be vacuum filled because it’s pump isn’t strong enough to push air bubbles through the battery. If you get air in, and don’t get it out, you risk local overheating of the battery.

      Correct. It was a nightmare lol! Man...it was by far the most difficult radiator replacement I've ever done. Although, I spoke to someone else who recently did this job and he said if you remove the two lower radiator support brackets, you don't have to remove the front radiator or the others in fact and it creates more room to drop it down from below. Regardless, I would say this was an 8 or 9/10 on difficulty. Definitely 10/10 when it comes to a radiator replacement. I wouldn't want to do it again, but now I'm curious to see how much easier it is with the lower brackets removed.

      Your experience and tips are invaluable, especially for anyone else tackling this job.
      The design is definitely flawed, particularly with the main radiator holding all the others. It's incredibly annoying and very unnecessary. Your workaround with the Dremel to avoid draining the AC and transmission cooler is quite resourceful and time saver. And I can see why you'd consider plasma cutting the bumper bar for easier access-sometimes, a more drastic approach can save a lot of hassle. If/when I have to do this again, someone else mentioned removing the lower radiator support "horns" and it makes it easier to access the main radiator.
      Your advice about using the right coolant is crucial. Using deionized water instead of tap water to avoid conductivity issues and potential damage to the high voltage battery system is a great tip. It's clear that the sealed radiator cap is there for a very good reason!
