Reported cause
This can block air flow, but a more common problem is the trash holds moisture and with salt present just about everywhere this can corrode the A/C condenser and radiator and one or both can leak.
Leading evidence: 'trash holds moisture' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'trash holds moisture' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check coolant level' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

That's exactly what I used when reading coolant temp.

I'll definitely check the coolant level when it cools down and when i get some free time i'll clean out the radiators!

Just double check your system to be safe as Macster noted.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi All,
My car has been got very hot today when i was in stop, start taffic.
Is this too hot or is it normal for this type of traffic. (Pic attached)
Thanks Guys
Jack
i have a 99 996 C2 Manual Cab with 103k on the clock. fully serviced
203 Fahrenheit... sounds normal in heavy stop/start to me... well below boiling for coolant system... I have not experienced those temps, but I have not been in start/stop traffic...
I am sorry but your link shows your from the UK, the phrase 'Very Hot Today' doesnt fit, perhaps very wet today would be more appropriate
Having moved to the US from the UK 2 years ago, it feels alot hotter here I can assure you, I am sure your car is fine
Thanks all for your rapid reply! I suppose what I was looking for was "yes, that's normal. Now go away and drive your car" which I essentially got!
@rossclifford - you are right on the money with the weather!
However today was 24c with beautiful blue sky's.
I'm sure normal service of rain will resume in no time!

Last Friday I drove to Portland, Me. with an ambient temp. of 80F and my coolant temp was reading 89-90C. On the return home ambient was 85-86F and my coolant was as high as 103C in traffic but dropped to 90-92C on the highway.
Jack:
I live in Florida, so I experience these temps all the time. My gauge is in that position almost every time I drive it, so don't worry.
BTW, I also have a '99 C2 cab.
Now, go drive it!
The gage is not reliable indicator of the coolant's temp.
So you really do not know the coolant's temperature. And as for it being too hot...
First, is the coolant level ok? Be sure to check this cold and you may have to remove the coolant tank cap and even the screen to visually confirm the level is ok.
After some time the tank gets stained and it is hard to verify the level is ok by peering at/into the tank.
Anyhow, if the level is ok you've got nothing to worry about.
The word I got from the factory -- via a helpful SM at the dealer where I bought one of my cars -- is if there is no warning light on there is no coolant level, coolant temp, engine compartment fan problem. IOWs, everything is just fine.
But you want to make sure the coolant level is ok. If there's a leak the system can't hold pressure and this can result in localized overheating, which may not show up via the dash gage or warning ilghts -- and serious engine trouble can be the result.
You want to be sure both fans come on -- they should come on when the coolant temp reaches 212F and shut off when it drops to 205F. If the temp rises to 216F, the fans are switched to high speed.
BTW, the fans run all the time when the A/C is on.
Lastly, be sure to keep the radiator ducts free of trash. They can really collect the stuff.
This can block air flow, but a more common problem is the trash holds moisture and with salt present just about everywhere this can corrode the A/C condenser and radiator and one or both can leak.
Not good.
Sincerely,
Macster.
Thank you for your replies!
The fan does come on when it gets to a certain temp.
I'll definitely check the coolant level when it cools down and when i get some free time i'll clean out the radiators!
Thanks again all
Jack
Yes, that is where mine was this weekend in similar 100' degree weather and the a/c running full blast. I am hoping this is average and well within the normal range
We are over 100 F almost every day here and in stop and go this is totally normal. My car runs at that same temp. Just double check your system to be safe as Macster noted.
Since you have a MK1, you should be able to get more accurate temp readings by following the instructions in posts

I sure wish this worked on the MK2 cars.
