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?

My 2005 elantra hvt 2.0 has oil leaking into the air filter coming through or near the throttle body, I've been told its an egr valve.
If it is...where is it and how much for a new one and is it an easy fix? If not what could be causing the leak?

Took off throttle body on 3800 series1 S/C and coolant is leaking from both bottom ports from mounting area on motor. Is this normal ? Intake area into S/C was dry but very much build up. The 2 ports just end at bottom back of throttle body and are sealed by the gasket. Coolant comes out steadily from those 2 holes. Is this an intake problem, gaskets ?

Issue on my wife's 2002 SC430. Recently ran into the well-documented disappearing acceleration caused by one of the trifecta of sensors on the throttle (TPS, APPS, and Throttle motor). Replaced the throttle position sensor and seemed to resolve issue. As of about a week ago, however, the car has developed a hiccup that I can't diagnose. Here's what I've recorded and done so far:
Symptoms:
-Hesitation at 1800 or 2300(?) RPM under light throttle and increasing load (often on uphills).
-Throttle down-blip of 100-200 rpm momentarily, only lasts ~1 sec
-Noticable lurch to vehicle, slows down slightly, results in 0.08G accelerometer reading when kicks back in.
-Change in engine exhaust sound as if in C-gate gears on a downhill (sounds like engine braking).
-Sometimes happens repeatedly in quick succession - up to 8 times in 10 seconds.
-Not speed dependent
-Overall performance is fine, not sluggish or hesitating when you stomp on it.
-Intermittant issue, not replicable, happens at random.
-No error codes thrown, no CEL, no DSP lights.
-Consistent -14.7psi vacuum registering on OBDII
Actions taken:
-Recently replaced and tuned throttle position sensor
-Seafoam on a nearly empty tank for 3 mi, half-full tank for 40mi
-Italian tune-up
-Disassembled and cleaned MAF
-Cleaned air filter (K&N)
-Reset computer (battery grounded for 10 min)
So... the question is, what the heck is this? Here are a few thoughts of what to do next in order of easiest/most likely/least expensive:
-Remove ABS relay and check performance (maybe TCS is hitting brakes a little?)
-Check all vacuum lines
-Seafoam cleaning through vacuum lines
-Remove, disassemble and clean TB assembly
-Test continuity on throttle body motor
-Test continuity on VVT solenoids
-Test continuity on full range of APP Sensor
-Replace VVT filters
-Replace VVT solenoids
-Check spark plug torque?
Lexus SC430 :: 2002 - Top Leaking On Both Driver And Passenger Side
If the top is leaking on both sides by the side top front windows, is that expensive to repair? I think it might need a weather strip. In other words, when it rains, the car will leak on my thigh and or the passengers thigh.

Just wondering if there's been any incident where the coolant in the SC430 is leaked into the gearbox at the radiator. I mean, these cars do have the transmission fluid running through the radiator, right? I've read that this occurs a lot on LS430 and many Mercedes models.
Would it be a good preventive measure to replace the radiator anyway? Or, is it ok to wait till there're signs of such leakage (if it doesn't usually begin as a major leak)?

My engine coolant is low, so I just picked some up from toyota to top it off. The bottle says to see the owner's manual for the proper ratio. I don't have mine handy. The best I could find was this PDF posted by Bob. But it doesn't have the ratio. What it should be?

My car is in the shop and has a leak at the Power Steering Pump. The rubber O-ring on the Power Steering Pump Solenoid Valve (p/n 4417030120) is leaking fluid. The Solenoid Valve is ok, just the Rubber O-ring is bad, but it looks like you have to buy a complete new Solenoid Valve to get the O-ring (a lotta bucks).
I did find a Lexus Power Steering Pump rebuild kit online at, but I can't see if it includes the solenoid valve o-ring or not. Have to replace their solenoid valve o-ring?
Golf/GTI VI :: 2010 - EPC / CEL Came On - Throttle Body?
So while driving yesterday I had a EPC and Check eng light come on and go away shortly after... maybe 1hr of drive time. Any way I took into dealer today to have them scan and they stated it was an issue with my throttle body.
Now as soon as he told me that he also said he can not do any work under warranty on my engine due to Stage 2 software and intake/down&mid pipe...... no big deal as I figured he would say something like that anyway. Should I take it apart and try to get it cleaned..... or what?
Its a 2010, with roughly 21k miles.... Had APR stage 2 for a few months now and this is the first thing that has come up.
Lexus GS 2013+ :: Coolant Reservoir Cap Leaking
What's with this coolant reservoir cap keeps leaking coolant?! I've been having to clean mine every few hundred miles now. The dealer overfilled my coolant but I already drained them out to just below the Max line and it still pushes out coolant. It was much worse when it was overfilled though. Now it's barely visible under the cap. Toyota of all people doesn't know how to design a proper coolant cap? On a 60K car? Can u all check under the hood and see? Cause u might have coolant leaks all over.

So i recently bought a used 2003 camry le 4cyl with 72k miles on it. So it's still in good condition. Previously I had a 92 camry 4cyl which is run with throttle cable. The new generation camry's now are drive by wire or driven electronically. So I decided to check out the whole car and looked into the throttle body, the out side of the butterfly plate, and notice some thick black substance. It seems like grease or oil. I don't know if its there to lubricate the motor to run the plate or just oil.

When cranking there is no fuel from the throttle body. Dropped the fuel line on both sides of the filter that was replaced last fall and have good flow before and after the filter. If I spray starting fluid down the throttle body it will fire. Switched out the throttle position sensor and idle air control valve to no avail. It used to die after warming up every so often at a stop light but would start right back up, now it just quit and wont start ???
