Post Long Block Replacement Experiences

Well, after looking again today after this week's trip I was looking at the truck again and they didn't fix the seepage that I had on the engine side of the coolant system. The hose clamp was slightly loose. I guess I will replace the hose and both clamps.

 

Those are not OEM clamps. Unacceptable

 

Got my truck back yesterday after getting the engine replaced and 4 other safety recalls. Had 35k on the original 2021 build without any issues but I do think it was getting louder at idle over time and was starting to notice some nocking when towing on acceleration.

dropped it off Tuesday 8 am. Received the truck Thursday 3 pm. The engine itself only took 2 of those days.

The new engine is noticeably quieter. One of the recalls was a transmission reprogramming. I have noticed some
Clunkier shifting but I’m hoping that will go away as the computer learns. I only have 30 miles on the new engine so far. Planning a proper break in like when the truck was new. I intend to Have this truck a long time.

I also mentioned some minor wind noise and they ordered a wind noise kit. I don’t think they even took it on a test drive there’s just a TSB for wind noise and probably deal with that all the time.

My Toyota rep was worthless for information as I’m used to and expected. Pretty sure they must have had to change the transmission fluid correct?

 

Do you (or anyone else) happen to know the TSB for wind noise?

 

I'm guessing they ran out of factory clamps and just went to local ace hardware across the street for something similar?
Maybe half a turn on the screwdriver would stop the leak?

 

Yeah, we told him those weren't factory clamps when he first discovered a leak after his engine replacement. Apparently he never did anything about it.

Manufactures haven't used those worthless worm gear hose clamps for decades.

 

Um why not use the ones that were there? I usually just slide the clamp back onto the hose when removing the hose and when it's put back in place, I slide it forward. Absolutely no reason to lose the clamps. Looks like a tight area so maybe the tech found it easier to use the worm screw clamps. The flexible tool you use to deal with these clamps should be in EVERY Toyota technicians tool box. As the guy said below, those worm screw clamps suck.

 

I wonder if the plastic neck is cracked and leaking and the worm clamp was used as an attempt to stop the leak

 

This is why many drivers, including me, say that the truck will never be the same after the repair of that magnitude..

 

I thought this too as it looks like the infamous "cracked coolant pipe" on the back of the 3rd gen Tacomas. Guys got three worm screw clamps on in different places so maybe the tech was chucking clamps at it. Definitely worth looking into

 

Both ends of that hose have the worm drive clamp. I got a good 1/2=3/4 turn on the clamp but will replace the hose and clamps.

 

While you're entitled to your opinion, I don't consider a couple of hose clamps a major issue. It will literally take the owner, or dealership, about 5 minutes to replace those clamps with the proper OEM style clamp.

The vast majority of owners, who have had engines replaced, have reported improved engine performance with zero problems. Most replacements are being completed in 2-3 days, which tells me the techs have it down to a science.

Assuming the old engines don't blow before being replaced, which the vast majority haven't, this recall could be viewed as a bonus, and many do. Heck, my truck isn't included in the recall, but I'd love for Toyota to offer me a brand new engine after I've put 50-60K miles on the current one. I would do it without hesitation or concern.

 

Unless the engine was about to blow up…

 

What has everyone experienced as far as fluid changes? Ive seen mixed information. Is transmission fluid done? Mine is scheduled for engine replacement in just over a week and I'll be just hitting 60k at that time. If they're going to charge a ton for transmission fluid service I may just do it myself. What has your experience been?

 

I had a coolant leak in my 22 at 800 miles. It was a coolant tank support rod and clamp the service manager told me looked like it came from Home Depot. Year into the 22s he said never seen one like that before. Not standard OEM.

He canned the parts so I did not see them.

Lots of strange stuff happens at factories, dealerships and the Toyota regional middle man lots

 

@Jymbeux Just had my engine replaced this week. No notation of xmsn fluid replacement. BTW, 55,500 miles on the original and no issues. Dealer put me on the list for replacement after asking what the process was. 3 wks later they said bring it in.

 

I had the same question, as there was a line on my ticket that claimed “transmission fluid 1”, but they only top it off a bit, maybe a quart. Farther back in this thread there is a good explanation. They also do not change the air filters. And they may not Re-set the oil maintenance.

The new engine is great though, I am about 7,000 miles on it and 1 oil change. It idles better, and my transmission has relearned and back to smooth (that actually didn’t take long) and with the summer weather and summer fuel, I am regularly back to 20-23 Mpg’s in many instances,

 

Great feedback thank you! Good to know about air filters. Ive got the trd ones. Also have a fumoto drain plug I'll have to make sure they don't toss. I have very low faith in my dealership, but I've gone to a few in the Puget sound area and none have impressed me.

 

I too had the Fumoto drain plug. I talked to the service advisor about it and left a Ziploc bag taped to the Info screen. I was able to talk to the tech and he reassured me he would make it happen.

 

Not sure exactly who is maintaining that, but they can add my factory motor failure... USA, 2025, Limited, non-hybrid, 6/14/2025, May 2025 (not sure where to find exact date), 5TFWA5DB2SX311942, 1270mi, No towing, no maintenance performed yet, no break-in oil change, very light ticking at engine start up about 10 miles prior to failure, daily driver, stock everything else, 87 octane... Date of failure was 6/24/2025

 

Wow. Didn’t know 25s were also having issues.
