r/CT200h

Did my headgasket swap 2 weeks ago and put about 400-500 miles on my car already since then. Was surprised how fast the job really is when I did it. Scariest part though was I had a headbolt that did not want to turn even with shock on the headbolt and it ended snapping in the block. Ended up drilling the bolt out after multiple failed attempts of trying to back it out with several tools. After that bought machine taps and used a straight square to re tap the threads and then put the motor back together in factory specs. Overall not a bad job just had that moment which made it stressful. If your wondering what gasket I used it was the felpro brand that’s blue also new headbolts from felpro.

Hi everyone, I just recently learned that for our CT200h (or 3rd gen Prius), the reasons we experience coolant losses and the engine shudder (cylinder misfiring) is through coolant seeping into the cylinder heads. I used to think my '12 CT200h can hit 400,000 miles before it experiences these potentially catastrophic failure but I guess I'm at the juncture lol.

It sounds like there are three main pathways: 1) blown head gasket, 2) blown EGR cooler (coolant enters intake manifold), and 3) maybe heat exchanger / exhaust manifold (mainly for 4th gen Priuses).

I'm awaiting for a mechanic my friend had recommended to come back from vacation but was wondering whether it is looking like a blown head gasket for my vehicle.

No one here in Ontario, Canada, be it on a Canadian discussion forum or reddit, seems to be able to refer me to a shop that can do 4th gen engine swaps so I may have to go with a 3rd gen engine swap or have the head gasket replaced though from what I have been seeing, these head gasket replacements are not foolproof and could blow again in less than 50,000 miles of traveling and I drive a lot to work and back. Also, do head gasket replacements really take anywhere between 10 to 20 hours of labor work? I will go with Fel Pro as that seems to be praised by the Prius/CT200h community/owners.

What are your thoughts? The Engine Coolant Temperature has been quite stable when I had not unplugged the EGR cooler and ranged between 88 to 93C or 190 to 200F.

Has anyone used California-based Thermaweld for hybrids? It seems all stop leak are temporary band-aid solutions haha:

Many thanks!

Hey everyone,
I bought a 2018 Lexus CT last year (UK) and recently noticed paint bubbling on the roof panel right where it meets the top rubber seal of the windscreen. It started out as just a single spot, but I can now see a second spot starting to form nearby.
Before I hand over £160 to the Lexus dealer just for a diagnostic assessment, I wanted to get some community input on a few things. Has anyone successfully claimed roof edge bubbling under the Lexus 12-year anti-corrosion warranty, or do they immediately write it off as stone chip or surface damage?
Also, what should I realistically expect an independent bodyshop to charge to treat and respray this area? Does the glass usually need to come out to treat rust along this edge properly, or can a bodyshop safely tuck behind the seal?
Appreciate any advice or prior experiences!

TLDR: What mileage were you at before you got they hybrid system warning light?

I did the Dr. prius battery health test on my 2013 ct200h. The result was "fair condition", but it stopped before the countdown was finished. I think it still had 3 minutes left when it went to this screen. Not sure if that is normal. I haven't had any errors pop up, but I am having to take it on a 2000mile trip next week. It has about 133,000 miles on it now but it is very well maintained. I recently removed the hybrid fan and cleaned it, changed spark plugs, bunch of fluids just flushed. I am going to take apart the egr system and clean everything when I get back. My MPG right now is pretty crappy, but most of my driving is short drives in town with a lot of stop and go traffic. I'm wondering what mileage you were at before you had to replace the hybrid battery?

The car is a 2015. Took about 3 hours cause my car hated me for sticking my hands where they shouldn’t be and pierced a vein in my finger.

What do you think?

What seat covers do y'all have if any? Why?

Facebook had a ad and I fell for it!

I wanted to keep my seats clean, it was advertised as breathable which the ct seats definitely are not and it had a lady grinding the back seats haha.

What do y'all think?

2011 type A.., was quite expensive but a gem for the low mileage- this was the mpg whilst driving long distances in eco mode during a road trip

Hi everyone,

I just bought a 2013 Lexus CT200h and I want to replace the original screen with one that has Android Auto. Important detail: my car has the pop-up/flip-up screen, not the fixed one. I know this changes a lot for the dash kit and the unit that can fit.

My car has only the rear camera. I don't know much about car audio systems, so I have some questions for people who already did this:

Which double-DIN (or single-DIN) units actually fit in the pop-up screen space? I guess not every unit works here.

Any specific product you can recommend that worked well for you, with model name if possible?

Is there a dash kit made for this pop-up mechanism, or do people usually modify something?

Can I keep the rear camera working after the swap?

My car has the trackpad on the center console. Does anyone know if it's possible to keep using it with an aftermarket unit, or does it stop working after the swap?

Is this an easy DIY install, or is the wiring and the pop-up mechanism too complicated? Would you say it's better to pay a shop for this?

If you have photos, videos, or links to the exact product you used, please share! Any "watch out for this" advice is very welcome too.

Thanks a lot

Last time was 20k miles ago
