Overheating while iddling 2.0T

[Bob Burd]

I like how it was casually mentioned, "they replaced the water pump and then the engine." This sounds like a nightmare. 244F is not healthy.

ever been through mud silt sand? might be blocked radiator.

If its not leaking, thermostat is good, water pump is working, is it? Otherwise you have internal blockage. To bad in todays world the kids at the dealer have to progress step by step via a thick book instead of using some simple diagnosing steps.

What codes is it throwing? Do you have your own code reader ? autozone for free.

reading first post, new water pump, then a fried engine.

But did they replace the radiator?

Sounds like bad rad to me…. Or an obstruction? 10mm socket? ?

I thought that, but it wouldn’t make sense for it to be the thermostat if it only overheats when iddling and not when I’m driving.

Actually, you're incorrect and I mean that in a kind way.

It's exactly the opposite of what you're saying.

When you're driving, water is flowing and it's also getting air cooled at the same time. This lowers the temp.

Your temp will drop as soon as you start driving. The reason it overheats at idle is because none of that is happening.

If this was back in the day and you were talking a V8, I most definitely would say it was the thermostat. I've had this happen many times.

Hold on a second. This was happening before having the water pump and engine replaced? And it kept happening afterwards?



PM me your VIN and I'll be able to give you anything logged within service library for it.


Edit; Echo PM'd me their vin and my goodness this thing is a nightmare I'd strongly suspect a blown head gasket based purely off its service history; no diagnostic needed.


The ECH has been replaced twice in under a year (LOL)
The water outlet was leaking not once but twice, one RO directly states engine was overheating
The 3-way coolant valve was replaced
The HV battery has been replaced for the B9A recall

ALL of this within a 20k mile period. Absolute ridiculous.


On a side note its been passed around every dealer like a bottle of whiskey. Just about every single dealer in the southern California area has had its way with this thing at one point or another

Boy.... but I bet he got a good deal on it ! ??

A vehicle with a stuck shut thermostat will overheat even faster when driving due to the greater heat input to the system with no heat removed via the radiator. You seem to think air flowing under the vehicle will cool the block enough to matter, it will not.

I'm not sure why you presume to know what I think... but ok. ?

I never made that statement, that is how you interpreted what I said.

You're assuming or atleast I'm interpreting what you're saying as you think I'm talking about a thermostat stuck closed... but people that understood what I wrote, know I was referring to an open thermostat.

Clarification wasn't needed because my comments correlated and pertained to the symptoms the OP was having.

An open thermostat results in LOW operating temperatures, I'm not sure what you're going on about but it isn't relevant by any means.

I believe that what I said.

water is flowing and it's also getting air cooled at the same time. This lowers the temp.

My comments were in context to a comment the OP made, not a diagnosis for his overall problem. He said:

I thought that, but it wouldn’t make sense for it to be the thermostat if it only overheats when iddling and not when I’m driving.

But after rereading, I realized I miss spoke when I used the word "overheat", when I mearly ment, the temperature would rise at idle in comparison to driving.

Just happened to me today for the first time. Fine in the morning. Got out of work about 9 hours later and heard the fan a little louder than usual but didn't make anything of it. Luckily, I'm just a few miles away from home. After a few red lights, noticed it getting louder and even my daughter mentioned it. Again, didn't think anything and actually looked at the gauge and was still normal. All of a sudden it spiked and went pretty much to the top of the H, while stopped. As soon as I took off, it came down. As you can see, I only have 9,175 miles. Already had a bad blower, 2 dead batteries caused by ESS and now this. I've had four Wranglers, all 3.6's and never had an issue. Was very skeptical about a 2.0 4-cylinder Turbo, but it does drive nice. Two years in and under 10k miles, this is ridiculous even if I have warranty. My question / concern, should I drive it to the dealer or have it towed? I'm calling them tomorrow but have seen some threads here that the dealer didn't want to pay/cover because they said the owner was negligent. And on a funny note, and no joke...I have scheduled an appt to get a new tattoo Friday and was gonna sneak in a silhouette of a Willy's Jeep in there....seriously...Now I'm wondering if I should wait since hopefully this doesn't draw me away from the Wrangler.

Based on your mileage it most certainty is a leaking water outlet, but that's just a common guess. Fill the coolant and drive it to the dealer or call jeep and have them tow it. You won't have to pay a dime.


As to the dealer declining repairs there's just no way? What dealer could lie so blatantly like that? Negligence for overheating a sub 10k mile new Jeep? Come on. Name and shame that dealer. Absolute scumbaggery.


At my shop you could overheat it and drive it until the engine locked and we'd cover it no questions asked. Absolutely ridiculous. It isn't your fault our vehicles' build quality has gone into the gutter over the last few years. I never understood these stories about dealers declining warranty repairs on bad faith. I've never seen it happen myself and both dealers I've worked out went out of their way to get things good willed left and right to the point of it getting annoying.

 

[AJCFLA68]

Just got it towed to the dealer, let's see what they say. They called me and said it wasn't doing it so lucky I took pics and a video showing it and you can hear the fan really loud. In their hands now.

****UPDATE****

New temps while driving on the highway.

 

[Pape]

to echo @SargeDiesel some time thermostat when going bad require some assistance to open up and this show up as extra water pressure that increase with rpm.

I did have a similar issue on the JK but I was also having the water fall therefore air in the system. Except for the water fall symptom it was the same, high temperature while idle and normal temperature while driving. Was usually seeing this while waiting at the drive thru, my simple answer was to just rev the engine at idle to create more flow.

Yes i have to rev up the engine while idling so the temps go down
