I'm sorry if this has been asked before, but does anybody know what this is? This is my lower coolant reservoir. It's not exactly murky, but it's brown. Last night I got a coolant low indicator and decided to check the coolant reservoirs. The smaller one was nearly full and was green like I...

If a radiator leaks in any way that's not related to damage from an accident or maybe stone damage including cracking or a leaking end cap assembly seals then it's covered by warranty, at least here.

You shouldn't really mix the G48 fluid with the HT-12 fluid. Will anything nasty happen? probably not in the short term but it's not good practice to mix different coolants. The HT-12 is now used primarily for environmental/recycling reasons from what I can tell so it's probably shite as most...
Local dealer added UV dye to trans fluid, drove for 40 mi and found the fluid was coming through one or more of the pan bolt holes. They filed a TAS case with Toyo and it was approved for a new transmission replacement under warranty. Just received it back after 2 weeks and so far so good...
Tried installing mine and the fitment wasn’t great. First, the ends of the two hoses from the back of the manifold did not clip into the oem connections so had to replace them with ones that fit, luckily I found some just slightly smaller. The other issue being the two metal brackets where the...
Update: disconnected and removed everything from the hot side of the car
Taking measurements and starting to weld the turbo manifold. Trying to figure out what all the lines I disconnected are for.
Other than this my turbo doesn’t use coolant so I’m capping of the coolant lines. Not sure if I...
Here's an excerpt from the owners manual.
The coolant may be overfilled in the coolant reservoir when the vehicle is delivered from the factory. The normal coolant level is achieved by operating the vehicle for a longer period.
So if your car wasn't overfilled slightly from the factory and the...
Everyone keeps talking about this cap/tank residue like it's a fault. It's not necessarily the case. Here's an excerpt from the shop manual.
When driving at high ambient temperatures, the design may cause the pressure relief valve in the reserve tank cap sub-assembly to open slightly and air to...
So I got the low coolant alert today as I was about to take my kids on a joyride. So much for that idea unfortunately.
Popped the coolantcap off and do not see much in the way of corrosion buildup around on the cap/reservoir threads. There is SOME but a very light amount (nothing like the...

Common issue with the coolantcaps. Check that first. Also what Razorlab said
This is a major mistake. never take samples from the bottom of the sump always mid stream. I've had plenty of experience monitoring cooling systems over the years and this is what I would do. If you are going to keep doing analysis then next time send a sample of unused oil left over from the...
That’s a good idea, can I just buy a Z4 coolantcap? It’ll be cheaper and faster to get than a new one from Toyota. That’s crazy because I’m also trying to mod my Supra, I have all my parts but don’t wanna add things until I figure it out.
Do you smell coolant by the reservoir after driving it? I’m super sensitive to the smell of coolant and I have that scent near my drivers side. Can not find a leak and replaced 2 caps. Dealer checked it out and said no leaks and pressure test was fine. Water pump was fine as well. No leaks...
Ya I saw somewhere some had a sticker with there vin on the inside of the trunk to. Which o don't have.
Ya I stopped cleaning my engine bay unless I'm going to a show. To much dust and dirt where I live.
Most newer models have 3-4 locations here: driver's side door, dash front, hood front and possibly frame side or firewall. Maybe not a specification in CA so they don't do it, but seems strange they don't just add the "unnecessary/extra" badges at the factory for consistency.
