Prius C :: Driving Over 65mph Over Hilly Terrain - MG1 And MG2 Temps Too High?
Apr 2, 2013
My C4 currently has around 1500 miles on it and during a drive over the weekend of sustained driving over 65mph over hilly terrain I noticed my MG2 temps reaching 200F. Several times it exceeded 200F.
I'm using an iPhone app called Engine Link to pull the temp info. Noticed with a ScanGauge similar high MG2 temps during sustained speeds over 65mph?
From reading this board, my understanding is that ideally the temps should be ICE coolant > MG1 > MG2. But during sustained freeway driving mine actually is more like MG2 > MG1 > ICE.

For the past couple of days I have been hearing a window rattle. It is hard to figure out where the rattle is coming from, but my guess would be the hatchback door. It only occurs when I am driving on a rough terrain with a lot of bumps.

I'm having a problem with a rattle that's in the front end of the car. I only hear it when I'm driving over "off roads" (uneven terrain) and not streets. The sound is not entirely Metallic but sometimes I get to hear rubber against rubber. I already changed motor mounts and stuts mounts but the rattle is still there. Is there anything else I should look for? I've had this rattle for over 5 months now!

Been a while... Problem today while towing... I was in some hilly areas but nothing too .. I was pulling an unloaded trailer and experienced a significant loss of power and overheating. Engine started getting hot (almost to red) and then the transmission came up in temp. Made it to a rest area and all cooled down within 2 to 5 mins... but the strange thing about the power uphill is that it is happening at slow speeds as well... boost seems normal. Recently did the injector cups, so the thermostat is new (motorcraft), coolant is new, and put new o-rings on injectors.

I was driving my 99 honda civic at a steady 65mph on the highway for about 10 minutes. I was not accelerating or anything, when it cut out totally as if I turned off the engine. When I would step on the gas (still moving), it would not even hit/sputter or anything. I pulled off to the side of the road and immediately tried to restart... nothing.
Two minutes later, I try to restart, and it started right up. Get going another 5 minutes, and it does the same thing. This time I only waited about 30 seconds, then it started up again, but it 'missed' a couple of times just before it started up. Then it was fine for the rest of the drive to work, and hasn't stalled since (one week).
However, the check engine light came on the next day after the stalling episode, and has also been on since. The code is P0420 (which says that the O2 sensor before and after the catalytic converter read similar, indicating a bad catalytic converter). I'm not sure if this is, however, a downstream effect/ symptom of a larger problem (that this is not the cause, but the effect of a larger problem?)
Here are some extra facts that may be relevant, or may be totally random:
I occasionally catch a whiff of egg like smell (smells like it's running rich, and maybe it is heating the catalytic converter)
It seems to be functioning fine (no loss of power)... the gas mileage even seems OK-I filled up with a new tank of gas the night before the drive (I've since filled up again)-There was an ignition recall, that I did NOT have done (I just found out about it -The car is pretty beat up: 170K miles-Gas gage quit working about a month ago... always reads full.

While most of the emphasis I've seen on improving fuel economy seems to focus on warming the car up quickly in cool/cold weather, I seem to be experiencing significant mpg drops at the other end of the spectrum.

OK, I thought I saw where people were lubing certain areas for a clunk but it was a squeek.
Seems like over rougher terrain my 11 sunroof tends to clunk. However the painful part is I can't reproduce it on demand, clunk or a rattle. Its deeper in tone for sure and not a squeak.

The transmission feels like its slipping while in drive. Oddly though, it shifts great using 1st to 2nd to Drive, then using an on / off switch to control 3rd to Overdrive/4th. Its automatic and I am just using the shifter to control shifting, because the car doesn't seem to downshift on its own either. It will stay in Overdrive/4th even at 35mph with the pedal to the floor, only sometimes downshifting after awhile. The car also hesitates slightly while driving at above 65mph on highway. It stops doing so on hills, and it has no issues at lower speeds, even at 5k rpms. Not sure what that is related to. I just bought it, and the transmission fluid is black, not sure if its from lack of maintenance. I assume the transmission needs a rebuild, but the more I know the better I won't be ripped off at a shop.

I have less than 1000km on my new 2014 XTR SC. I had an AS 2.5/1.5" kit installed and a wheel alignment. There is a dull clunk in the rear when driving slowly over rough terrain(dirt roads n potholes). It happens occasionally when taking turns at lower speeds too. A friend who is a mechanic installed the kit and its the 4th kit he has installed for me. Never an issue.
The truck had to go to the dealer to have the remote start installed and they investigated the clunk and tightened up some nuts and bolts and its still there. They blamed the leveling kit and said its normal sometimes. This is definitely not normal! I've searched and can't find anything.

I bought my Prius 2 days ago and I am now on a long car trip. I think I understand how to drive the car, but I was fighting to get the car to stay around 50mpg - even on flat terrain it wanted to be down around 35. I tried using cruise control, I tried manual. Going up hill I'd get 19-28... almost always coasting to 99.9 down hill (though a couple times it would be low then too) but the flat time is what really killed me.

New 6.0 owner having some issues. I have read just about everything I can find on the ECT/EOT problem.
208K on it, its been studded, running a full banks system. Factory size tires. Since buying it I have drained and flushed with distilled 4 times before new ELC coolant (system looks very clean, no debris found at all), T6 oil change and cleaned the air filter.
I am having a large delta on ECT and EOT. Here's some data from today's run. There is a lot of it. Readings from every minute.
Ambient Temp 118 today, took it for a run up the highway cruised north at 65 mph and back south at 75mph. I was driving on Saturday at 75mph and got the wrench light for excessive delta with 232 degree EOT.
45mph on the way to the Freeway- ECT 195.8, EOT 213.5
65mph after accelerating lightly- ECT 197.6, EOT 216.4
10 miles later, flat 65mph cruise set, it maintained a reasonable temp hold and reached max of ECT 199.4, EOT 218.7
After 2 minutes of coasting down off-ramp and sitting at a light- ECT 195.8, EOT 213.5
after reaching 75MPH moderately- ECT 201.2, EOT 216.5
1 mile later, holding 75mph- ECT 204.8, EOT 220.2
2 miles at 75mph- ECT 204.8, EOT 224.6
3 miles at 75mph- ECT 204.8, EOT 225.2
4 miles at 75mph- ECT 204.8, EOT 226.4
5 miles at 75mph- ECT 204.8, EOT 227.3
6 miles at 75mph- ECT 204.8, EOT 228.2
7 miles at 75mph- ECT 206.6, EOT 228.5
8 miles at 75mph - ECT 208.4, EOT 231.0
At this point I dropped cruised and coasted to the next exit, a mile down.
After coasting to exit and sitting for a minute- ECT 201.2, EOT 221.0
After a mile at 45mph- ECT 203.0, EOT 221.6
2 miles at 45mph, lightly on throttle- ECT 204.8, EOT 221.0
After idling stopped for a few minutes- ECT 195.8, EOT 213.8
Driving again lightly at 45mph- ECT 203.0, EOT 211.5
Am I just ignoring the obvious oil cooler issue or is this a water pump, etc? I changed out the thermostat again for another motorcraft unit after Saturdays hot run. I swear it did not run this hot when I got it... but I question if they were running nearly 100% water in the system. What EGR cooler there is, if there is a way to tell without disassembly?

It's been pretty smooth sailing since I installed my BPD oil cooler a couple months ago, oil temps are great now. However, in the last month or so, since the outside temps have gotten hot, I'm noticing that my coolant temps seem to be a little higher than they should. I put a new Ford thermostat in it back in the fall when I flushed the coolant system and refilled with EC1 coolant. The temps I'm seeing range from 206 up to 222 and I have seen as high as 230 when I was going up a long grade on a hot day. This is not towing.
The fan does kick on like it should, or at least I think its working properly. When the temp gets to 210-212 I can hear the fan a little, when the temp gets to 219 I can really hear the fan. It usually cools it back down pretty quick unless I'm headed up a long grade. Am I wrong in thinking these temps are too high for a 192 degree stat? My worst fear of course is head gaskets even though I don't have any other HG symptoms. No coolant loss, no puking. What other things should I check first? A new thermostat would be easy enough but I don't know if that would be the issue or not.

What kind of engine oil temps are too high? I know pulling the other day it got as high as 220 but I honestly only have the gauge cause I got it for free. Whats happening at the different temps? I know for trans fluid but not for engine oil..

I am having a problem with the clutch fan not coming on at high temps pulling a grade or flat. Replaced the clutch had the front of the radiator removed and all the debris blown out and replaced the thermostat. Still over heating and the fan comes on real late.

motorcraft coolant -system flushed
Stock EGR- No leakage
Deltas 3-5 degree apart no A/C on
A/C works great!
-Issue- When I turn the A/C on city on normal driving no loads or towing. The temps have gone up as high as 230 eot 230 etc. Ambient temps 83-90F ....

On my 2005 F350 Super duty 6.0 Power Stroke Diesel I have extremely high oil temps when towing and also have a warm start problem. I need to tackle both these problems at the same time but I am struggling to find the correct (and still affordable) parts for this. My local parts store and Ford dealer are way over priced.
First, I need an oil cooler (truck has an EGR delete so no EGR cooler).
Second, I want to replace all the seals in the high pressure oil system and replace the HPOP elbow.(Already replaced IPR)
Third, I would like to do the Blue Spring update as well while I am in there.
Looking for part numbers or kits numbers. I usually do all my own research but right now I am way too swamped at work and home to find these parts.

I have a 390 FE engine and whenever I am idling or waiting at a long stop light my engine temperature goes from the regular temp of 180 to about 190 to 210. How to keep the temp normal when idling? I have checked my fluids and they all seem to be fine, I don't know why it would be doing this.

2008 6.4L .... My ECT 191-197 and EOT 220-230 high side on interstate no load on truck air temp 70 degrees. Is this a sign thermostat failing. Is there a certain temp to determine if your cooler is fully clogged or just partially clogged? I plan on doing a flush with restore then restore plus. Is there any point in using restore with temps this high. Or do I have to break down and buy the half kit to bypass OEM oil cooler? I need this fixed ASAP hauling the RZR to arkansas in a week. I know ill mess something up if i try to pull a load with those temps.

I have a 2007 Camry XLE, all the bells and whistles it was offered with. It's got about 110k miles and is extremely well maintained.
I live in Vermont, where every road is a hill, and every hill is covered in snow. Recently, my Camry decided that it no longer wants to conquer these hills. I will be driving up, and suddenly it will stop. The engine is running, but no power goes to the wheels. I'll mash the pedal to the floor, and the RPMs do not even waiver from the idle position. And we're not talking mountains, I'm talking a nice easy hill with an inch of snow. Tires are new all-seasons etc. The traction light will 'maybe' flash, but nothing out of he ordinary.
A few weeks back, my Check VSC display came up, but went away with a little more driving. Could that have done this?

2004 F250 6.0 L. New head gaskets, ARP studs, new oil cooler, new water pump, all new hoses, new thermostat, 4" exhaust, EGR delete, new coolant bottle, radiator and cooling system flush, new injector seals and oil rail plugs all done at 98,000 miles. The truck is at 119,000 now and has been doing great since all the work. I have been frequently hauling very heavy loads and pulling cars on trailers and no problems. EOT has been staying about 7 degrees above ECT except on hill climbs. No coolant loss at all. Today suddenly while driving on the freeway (unloaded) the temps spiked. I pulled over when the ECT hit 240. Once cooled down I checked coolant level, hoses etc and since all was fine I took off again. Overheated again after about 5 miles. My understanding was that the Ford thermostat fails open if it fails. Do I have that wrong? Do I have a stuck thermostat? Some other problem?

I hear weird buzzing noise when driving it. It sounds pretty high pitched.
My Prius is a Gen3 2015 model 2.
