The radiator decided to end its life, as I was expecting it to happen soon, based on my experience with my 6GA's six years ago at the similar mileage. These Denso radiators seem like it can only last for less than 200K mi, when they're exposed to somewhat "extreme environment." In fact, this CL spent the most of its life in Indiana, and my 6GA's first few yrs were in Illinois, so that could be one of the reasons why both of my rads were done at 160K mi. I was expecting to get a crack on the surface or something, like I had it on my Accord, but the upper hose neck section got broken into pieces, and the hose got detached. Currently, the car has two aftermarket motor mounts, so I'm guessing the extra vibrations in the bay could have also shortened its life..

I was omw to work at 4:30 am in the cold ass morning below 32°F, when it happened. After a few minutes of driving from home, I started to smell the coolant from my heater duct, and lost the heat all of the sudden. The temp gage sky rocketed, and I knew it was done.. Drove back home immediately for about a few miles, and switched out the car to be on time to work.. Spent a few days of waiting and collecting parts + cleaning out the Blue Hawaii in the bay. Towed the car to the shop with the new parts upon arrival. (BTW, engine coolant can be one of the life hack things to stay away from mouse and rats problem in your home / garage / car, because engine coolant attracts and eventually kills them, since it's sweet & poisonous.)

The shop suggested me getting this aftermarket radiator by Koyo. I always like having OEM parts, but I decided to give it shot. The price was about the same as Denso's Internet sale price, so it was kind of promising as well. Even if not, I believe I can still rock with my Accord's factory one at the motor swap, since it's relatively a new one with the OEM hoses that came with it.

Got the car back from the shop, and drove it back home. I couldn't get enough chance to test it out spiritedly, but... Wow, this clutch pedaling is feeling so much different now lol. I'm still getting used to let it go faster, w/o the fear of getting the harsh engagement, but I like the fact that I don't have to step on it so much anymore in the first place. I need to drive it more to feel more actual differences.:driving:

EDIT: Drove it for a while to get the overall feeling of the difference. Noticed that the pedal has now a little bit of free play in the beginning for about half of an inch. This is why I feel like I only need to step on it so much less than before. The clutching is def faster and smoother on a city driving. It's a lot less likely to hit the stalling point, and move forward by idling, too. The highway driving seems to have small differences in feelings, but the pedaling became a lot smoother n quicker to shift gears and speed up. Overall, it's smoother, quicker, easier. Def sportier feeling than the factory feeling. Ill post up some photos later, when I get a chance, while I'm still allowed to edit things up here :lawl:

Seems like we can only attach 5 photos per post, so I had to throw out a new one up here, since I got a small update anyways.

Well, the battery started to get my attention for a replacement. I'd assume that this AAA battery (not the battery size, but it's branded by the roadside assistance company AAA, shown in the pic lol) was preinstalled right about the time I bought this car in '20. It was because it definitely survived this semi-harsh PNW winter weather(s) over the course of crazy climate changing years. For this car, I decided to get the Interstate battery for cheap, instead of my fav Optima Redtops, so I went out to Costco for it. It was kind of funny to purchase it over by the counter at their tire department that time, b/c their system kept telling them that the particular batteries were out of stock for the 2G CL / TL, yet it was still showing them that they're available for the 6G AV6, when I asked them that way lol.

Updated the OP once again after all!!! Posted another newest pic of the engine bay + the oldest pic of the car, taken by the car dealer for sale, when I found her lol. Man, it is so nice to say this phrase once again! :peace:

Had a chance to rotate the tires on my own, and replace the rusty lug nuts with somewhat newer ones from my OEM Accord's that I've kept them for a while, when I got the McGard's for my BBS wheels years ago.

There has been a noticeable gap between the bottom windshield glass panel and the cowl. It used to collect pine needles, and I'm sure this has also trapped the rain water and seeped into the dashboard, which inflated the panel surface over the course or years.

Replaced the rusty radiator holders with the OEM holders which I kept from the Accord's when I got a pair of polished holders by V6P years ago. These won't get carried on after the swap, since I'll be using the V6P's, but I just wanted to replace them anyways.

Ladies and gents, we finally have a vehicle-specific phone holder for our cars. Well, this is really for the 98-02 Accord, but I'd say why not for the CL & TL either. Until this, I was never a fan of having a holder with suction cups / air vent clamps, since the phone obstructs the driving view, and I didn't like the idea of my phone being so hot / cold by the heater / AC. Anyways, this one locates just about the right spot, where it avoids the air way, and my knee clearance when I clutch the pedal. With this thing holding my smart phone from now on, perhaps my CLS might have exceeded the factory navigation models.

Updated the OP once again with these new updates! Thanks for checking! :peace:

Darn, was hoping you were going to put the V6P radiator brackets up for sale. Shoulda known better :lawl:

One of the things I actually really enjoy about the 6GA is that getting into it is such a refreshing step away from the constant tech being stuffed into newer cars and subsequently, our faces, and it's such an invigorating step back in time. I put my phone in the center console cubby and don't look at it until I get out of the car.

But it is interesting to me someone thought to engineer a holder that would fit in these cars haha...though I'm guessing the accessory holes in some newer Hondas were the same...not sure.

Oh, not a chance. Those are def keepers for me :favorites37:

Yes indeed, it is a little special feeling for me to stand out from the crowd of tech-spoiled SUV's when driving this V6 coupe in public nowadays. However, I believe there are two contemporary features that this car (and my 6GA) is still missing; navigation & back-up camera. Out of all these crazily spoiling new techs we've seen now, I believe those two features to be very crucial lol.

To me, the only time I want my phone to be facing me is when I'm omw to somewhere unfamiliar, by being a visitor, using a navigation app. Otherwise, I'd throw my phone away like you. I never liked the ideas of getting those aftermarket phone holders (a/c vent clip, dash / window suction), as I've stated previously anyways. Thus, this is extremely innovative and revolutionizing.

It's because it locates right in between the gauge cluster and the air vent. I rarely use a navigation in the 1st place but, I feel much safer and efficient on my traveling, when I'm on the nav from now on. Yeah it's interesting, and I think it's also very respectful to see that this guy actually spent some time and effort to R & D such vehicle-specific add-on into this chassis with poor aftermarket support in the first place. At least, I am fully appreciated.

Not so sure if this will cover the 7GA + later Hondas / Acuras as well, but my 2G '10 Pilot has different shape for sure. This guy actually makes a few different stuff on a few random cars with different year, make, and models btw.

Sil2DrV6 can you share a link of where to buy such phone holder? Or at least the name of it, so I can google it? Thanks!
See the OP. :poke:
