Car temperature rising at higher speed
while going to work today, i was on the turnpike just going northbound, i was in 5th gear and as my speed rose to above 85 or so lol yea i know i shouldnt have been going that fast.
anyways the temperature gauge in the dash went from normal to almost hot.... as i eased off the gas and started slowing down, the temperature also went down. mind all of you this is the first time my car has EVER done this. the car is an 05 gsr with 45,700 miles. so my question to all of you is WHAT THE HELL IS UP WITH MY CAR? should i check the radiator fluid level? or could this be a sensor issue ? thanks for any help {thumbup} |
Yeah, it could be low coolant, it could be a bad thermostat, it could be a bad sensor. It also could be a blown head gasket.
|
Check radiator first. If the car overheated you should change the thermostat too. |
well so far the car is good, it just keeps on almost going to hot, but as i ease off the gas say when im the highway it will start to just go down slowly near the normal temp area. while im driving in say stop and go traffic the car is acting perfectly fine.
|
my sti did that and at higher speeds the temp went up....just cruising aroung little to no boost the temps were fine...but the min i stepped on it..air got in the system overflow tank was bubling and the end result was a blown head gasket
|
Your headgasket needs to be replaced, I 'd replace it before it blows out all the way.
|
Check your coolant level
|
and check for contaminated coolant and or oil.
|
i think i'll check the coolant levels first, i doubt the head gasket could have blown out. i drive the car occasionally, and i definetly dont dog it. i'll post when i see how the coolant levels are
|
the coolant tank was LOW, so im going to add some in and give her a spin in a little bit. i hope thats the only problem.
|
Add it directly to the radiator.

the radiator looked to be good. the coolant tank was at the low point on the tank. so i just bought some coolant and will add it in a little bit
|
we shall see ....
|
i filled up the coolant tank, afterwords took the evo for a spin around the neighborhood. once again at regular speeds seemed perfectly fine. now when i went on to a main street and gunned it it was ok , and i tried once again the temperature slightly went up. im curious as to should i check out the thermostate or possibly a sensor. if not then i'll be making my way to AWD motorsports monday morning and having them check it out..... ****ing sucks i hate having my car not functioning correctly
|
What did the coolant in there look like?

People are offering you advice and you're just doing your own thing. Stop beating on your car to solve the problem and actually try to fix it m8. 1. Add coolant and be sure that your coolant is good. You've done this. That's only STEP 1 in diagnosing. 2. Check your oil level and see if there's coolant present. Coolant in the oil typically looks like a whitish paste. If this is the case, there is a leak internally somewhere. Most likely, your head gasket. 3. You need to do a pressure test on the system while its cool. to be sure you don't have an externally visible coolant leak somewhere. If you find a leak, you need to fix it (obviously). You should also be checking to be certain the cap on the radiator is sealing properly. There will typically be yellow gunk around it if its been leaking. Same with the oil cap. 4. Check to see if your thermostat is functioning. Some people can do this on the vehicle by squeezing the coolant hose, and waiting until the thermostat opens. When this happens, you can feel the pressure in the hose change. My personal recommendation is to put it into a pot of water and set it to boil. If its functioning, it will pop open right around boiling temperature. If it doesn't open... it isn't functioning. 5. Inspect the belts and the water pump. Does your water pump have any shaft play? Is the belt installed properly, or failing somehow? You can also manually turn the water pump to be sure its actually movable. 6. Is there any type of blockage to the cooling system? Is your radiator fan spinning, and turning on and off as necessary? Is your A/C installed and does it work? Is it on when you're doing this? If you're ONLY noticing overheating at high engine loads, I would suspect it isn't a fan related issue. |
I've had similar issues in the past with another vehicle, fine normal, but under full load would ge hot. was the headgasket and it was spitting coolant too as the cooling system filled with exhaust gases.
+1 for headgasket unfortunately. |

i've added the coolant, and looked all over for any visible leaks. i didnt find anything at all. im going to check the thermostat next and check to see if the fan is spining also. thanks for the advice {thumbup} i'll keeo everyone posted

The leaks may not show unless under pressure. Just an fyi.

Take it easy on tomorrow's trip. If the head gasket is the culprit then what is happening is air is being pushed into the water jacket. This also means that coolant gets pushed to the jug - and, when full, onto the ground. So, things could go from bad to worse pretty fast.

Keep us posted on what this is/was so we can hone our interwebz diagnostic skills :lol:
|
well , i of course called ahead this morning before i left to go up on that 20 plus mile drive to AWD, it appears they arent open today or maybe they just open late..... if i dont hear anything back from them shortly then i'll just go to work like normal and try again tomorrow. sucks because i was looking forward to geting the car fixed today... oh well, what can you do
|
Same thing was happening to me. I changed my thermostat and all was well.

Head gasket is a possibility but usually you will "push coolant" into the over flow tank, so it's usually full when you check it.

well after dropping her off to AWD yesterday morning, i patiently was waiting all day to get the call to come pick up her. i ended up getting a call from shawn at around 5:30 - 6ish. he told me they were doing diagnostics to my car all day and they came to the conclusion that it is more then likely my HEAD GASKET......
So i had to end up leaving my blue beast at AWD overnight, but since my car is there not only will i be getting the head gasket fixed, im also having them throw in some ARP head studs, and take my old exhaust set up off and install a Greddy Ti and downpipe that i had sitting in my house for the last few months !!! |

How much does a head gasket job usually run for. Rough estimate.
|
I would have the Valve Seals replaced while your there and maybe have the Valve Lapped at the very least. If you have the money, have the head sent to a machine shop to clean it up.
|
I'm having these same symptoms with my Evo Viii. were you able to solve the problem?
|
well it depends how high it went up.... my coolant temp gauge use to fluctuate, never to hot though it would go to c, but the car wouldnt change its drivability while doing it. In my opinion your thermostat like some have said, if you do it I would advise a full coolant flush not a drain and fill, change all your coolant, even turn on the heater core, that way your coolant is circulated through that system, top it off see if it still does it, if so you may possibly have a clogged up radiator, hopefully. Not a head gasket. Good luck.

bumping this, temp also rose up on my gauge momentarily and went back down. Also coolant was sprayed on the top of the underside of the hood, but there was coolant in the reservoir
