Prius (Gen 1) :: Code P3125 After INV Coolant Pump Replacement
I picked up a 2003 that had a bad AUX battery and P3130 code. Just FYI, aside from the battery it drives fine. Kicks the Warning light after about 15 miles but since the battery was bad it kept getting reset. Replaced the battery with a nice optima conversion.
Took out the inverter coolant pump, tested the circuit (good), tested the pump (bad). Replaced with a new one from dealer. Set up the bleeder tubes and massaged the lines till the new pump stopped SCREAMING at me. Added probably 2 qts of TLLC total. Bleeder tubes never had enough pressure to push fluid back up to reservoir but got solid 2 inches of fluid with no bubbles. Topped of the coolant. Went for a drive around the block, made it halfway (about 28mph) before the light kicked in and the motor seemed to bog down. Limped back home and read the 3125 Code. Code reader does not give me sub codes.

Prius (2004-09) :: CHRS Electric Coolant Pump Replacement - How Hard?
After a long day at work, I stepped out of my '06 Prius and was greeted by an obviously struggling CHRS pump. It sounded like it was having a hard time maintaining speed, and to my ears was screaming; better replace soon...
View 2 RepliesFord :: 1995 - Coolant Leakage - Changed Thermostat / Water Pump
1995 Ford Van E150. So I've been trying to solve my overheating problem for months now. One morning I walked out of my house and all of my coolants was on the street. I could not completely detect the source of the leak after running more coolant through it. I also checked the dip stick and coolant on the ground for any sign of oil/coolant mixing. I started by replacing the thermostat.
I did a more thorough inspection and found a crack at the bottom of the radiator that I replaced less than two years ago. I replaced the radiator again and while I had the belt, intake and fan disassembled I switched out the water pump as well. The old water pump was gunked and the gasket was almost completely worn off. The van is still overheating and spitting out coolant at a much higher rate. I'm guessing because of the new water pump. A friend said it could be the intake manifold because of where the steam was coming from the motor.
Windstar :: 2003 - Coolant Leakage After Lower Intake Gasket Replacement
Well, I decided to take on the dreaded task of replacing the lower manifold intake gaskets and put in new isolator bolts. It was a major undertaking, and when I finally finished the oil change and fired up the car, it sounded fine. Then I checked under the hood.
I saw coolant spurting out the side of one of the hose connections that I had to take off and put back on. I thought the gasket on it looked pretty worn, but wasn't expecting this!
Unfortunately I don't know the name of the hose connection to pick up a gasket at the store ... it's the larger lower hose that is bolted on to the lower intake, not the hose slightly above it that has the plastic clips.
What is the name of this hose connection so I can try and find one at the store? It's a 2003 Windstar model.
Audi - A6 :: 1999 - Coolant Leakage Coming From Timing Belt / Water Pump Area
My audi runs great. Its has 170K miles on it. My mechanic replaced an air pump last Friday and by Monday I had a new issue. I noticed coolant leaking. I took it back to the mechanic who fixed the airpump to diagnose. He tells me that the leak is coming from the timing belt/water pump area and in order to get there it takes 7 hrs. He suspects that its the water pump or a cylinder block crack. He suspects it could be a water pump breakdown more than a block crack. A block crack could be a serious issue with the engine is what I suspect.
I think he did something wrong when he replaced the air pump. He tells me that these are in two different areas and that he canbe generous with his time in only diagnosis but not in fixing the problem. Do you think he is right ?
He recommends that when they open the timing belt cover its best to replace the belt, tensioners, water pump etc.. Now spending $ to get to know where the leak is sounds steep.
Prius (Gen 2) :: AC Won't Work Due To Coolant Leakage
I have a 2006 Prius. I must admit that I've never been satisfied with the A/C performance, but now I'm even less impressed.
I had the A/C system serviced at an "after market" place as our dealership calls them (about 2 weeks ago). They added just under a half pound of coolant, oil, and UV dye. The system was much improved after the "after market" shop serviced it and stayed that way right up until it stopped cooling. Two days ago, the A/C stopped cooling and I'm in town so I stop by the dealer. They do the same basic checks I did with the same results - checked the fuses-OK, checked the lines and connections with a UV emitter-OK.
They evacuated the system - removing 0.16 pounds of whatever was left in the system - and recharged the system with 1.06 pounds of 134a, etc.
Neither of us could detect a leak, assuming there was actually dye in the system.
There is no problem with the compressor .
They see no other issues with the A/C system, it was just out of coolant.
Where did the coolant go and why is there no visible evidence of a leak?
Aside from monitoring its effectiveness and checking for dye leaks, is there anything else I should check?
Should the sight glass have enough dye exposed to detect inside the system with the UV emitter?
What should I see (or not see) in the sight glass?
Camry :: Coolant Leakage After Engine Shut Off
Ave an 02 Camry 4 Cly
Noticed small puddle of coolant under the car - then noticed overflow empty and radiator a little low on fluid. Noted some coolant below the thermostat.
After filling back to proper levels, ran engine for a while with no apparent leaking. Took a couple of short trips and inspected after each trip and no leaking noticed.
Checked several hours later and noted coolant below thermostat housing and on ground. After a couple more trip noted coolant level dropping again.
What would cause fluid to leak after engine shut down? Could be coming from another location, but my attention is on the thermostat at present.

View 2 RepliesPrius (Gen 3) :: Coolant Touching The L Mark, Might Be Leakage?
A couple years ago noticed the coolant + inverter reservoir was on the low side. Took it to the dealer who pressure tested it and didn't find anything wrong, added a bit, and said good to go. Roughly 55,000 miles.
Today at close to 85,000 miles the coolant in both the radiator tank and the inverter is again touching the "L" mark. They were filled up to the middle/almost topped off after the dealer visit.
Just curious if others have had this issue and/or where to look. I haven't touched the coolant since purchasing at 42,000 miles in 2011.
This is the only issue I've had with this car so far. But it scares me, as coolant loss can be a big deal! Something as small as this isn't as concerning unless it's leaking some place I don't know about, or being consumed in the engine.
Prius (Gen 2) :: Coolant Leakage From The Throttle Body
My prius has a coolant leak, which look like it's coming from the throttle body. The stealership recommends a new throttle body. The mechanic said he has not seen coolant leak from the throttle body before. Is this the only fix to replace the throttle body?
View 8 RepliesIntrepid :: 1997 - Coolant Leakage From The Front Of Engine
My 97 Concorde 3.5 w/ 223k developed a second coolant leak from the front of the engine. Using a pressure tester I found it was leaking from the water pump housing o-ring (pass side) and also the o-ring behind the water pump itself. I did this exact repair 3 years ago including new pump! I do everything meticulously so this has me a bit frustrated. I've got it all torn down and cleaned up real nice, except there seems to be a lot of pitting in the o-ring grooves on the back of the water pump housing, mainly the large one.Can I use high temp RTV oil-resistant sealant in the grooves and then put the new O-rings in to make sure they don't leak from the pitting?
Also, I found the cam thrust plates to have hard, cracked seals.
Prius (Gen 2) :: Check Engine Light Is On - Inverter Coolant Pump Shot
My check engine light is on and I think the inverter pump is shot. I have a some questions about how and when the pump is on. I have a mini vic on order and as soon as I get it hooked up I'll run for some codes. That is if I get it installed????
1- With the car in "ready mode" and at start up (car cold) should the inverter coolant pump be running.
2- With the car in "ready mode" Should I always see a water moving in the water reservoir.

View 1 RepliesPrius (Gen 2) :: 2005 - Leakage By Coolant Filler Pipe
I was changing the engine coolant on my 2005 Prius today. When I went to fill up the tanks, I noticed a small pool of coolant right under the filler pipe. I thought I might have overfilled something, but when I jiggled the filler pipe, I heard an air leak. It looks like there is a bad seal between the filler pipe and the radiator. I also noticed that my coolant recovery tank was empty. I never noticed this before so I don't know if this issue is related.
View 12 RepliesPrius (2004-09) :: 2008 - ICE Water Pump Failure / Engine Coolant Losing
I bought my 2008 JDM Prius a couple of weeks ago, at 84,500km. After a week, it started losing engine coolant. (Great start! Hope it's not a sign of things to come...) Fortunately, covered by a 3 month Dealer Warranty - hopefully. Yet to make the claim.
Anyway, went to the local Toyota Dealer to get some of the proper Toyota SSL (Super Long Life) Coolant to top it up. Got chatting with the Service Agent about Prius Service and what HSD Adjustments are possible (not many) and showed him my symptoms.
Explorer :: 2003 With 4.0 Engine - Coolant Loss And Smell But No Leakage
I have an 03 Explorer with the 4.0 engine. There is a strong smell of coolant and the reservoir does go down slightly once a week or so. There is No Leak whatsoever that I see, I have checked under the hood, under the vehicle, under the dash, everywhere...nothing. Where is the coolant going? This seems to be a common problem, I work at a quick lube and almost all of these explorers are low on coolant when they come in.
View 2 RepliesPrius (2004-09) :: 2009 - Check Engine Light Came On / Coolant Valve Replacement
I have a 2009 Prius and the check engine light came on last week. I decided to take it to a highly recommended auto repair shop instead of the dealer. The error cord was P1121 and they replaced some kind of coolant control valve. When I went to take the car home I noticed the check engine light was still on and they said there was another similar but different coolant valve that needed to be replaced. They replaced the other part and everything seemed fine.
View 10 RepliesPrius (Gen 2) :: Preventative Water Pump Replacement?
08 Prius now at 120k. This is usually when I change the ICE water pump. I've been reading about when to change the pump, and it looks like opinions are all over the place. Generally though, consensus seems to be "change it when you see pink crystals on the pully." Is this correct?
120k is usually when I expect to drop a couple of thousand on preventative maintenance. Is this not true on the Prius? I knew running costs were low, but THIS LOW?
