Stands to reason this could be the reason I was getting a poor idle and a P0105 code. The P0105 is the whole reason I'm diggin into the manis, because I had to remove them to access the MAP sensor.

When the car cranked and idled fine, she ran like a raped ape. Trick was, getting it to idle.

No wonder the MAP sensor was on the blink...

 

John, that coolant does not look good, and you are considerably low. You should be full when the level is to where the clear meets the black. I would bet you need to add at least half a gallon, wouldn't be surprised if it took more than that.
Flush that puppy out before you do any running and try to locate the blue stuff for a refill.
Good luck!

 

I spoke with Steve last night regarding the coolant color, he said there was a MB-approved fluid that was orange. No junk in the coolant itself, it's clean and crystal clear.

I bought the car with 42K on the clock, 52K on it now and the fluid is as clear as apple juice. So, I don't think there's anything to be overly concerned with. Nonetheless, I will do a full flush and fill with the MB blue.

We did some open-heart surgery on the car this morning, she was definitely nasty. The intercooler was misting every sensor after it, the IAT sensor was completely coated. MAP sensor was relatively clean but it was generating a code.

I think the pictures speak for themselves

 

Looks like sumthin' Freckles lets out once in a while...

 

Hey a quick Q? The 4th picture top center, is that a hole in the tube I see? First tube top center?

 

That's roughly how it was running, too...

Could be, but if you can spot a single flaw in that big dose of f*ckup then you're a better mechanic than me

I think there's enough wrong with that I/C to give it the goodbye wave, no questions asked.

 

Looking at the color I think it is orange and therefore be Dex-Cool an OAT coolant, I have looked for other orange coolants and I cannot find any. Dex-Cool (OAT) an G05 (HOAT) do not mix. OAT is generally avoided from what I see.

I too would like to replace mine with the blue OEM coolant but it may be hard to find. MB coolant is G05 and as such the blue will mix with the yellow Valvoline G05 no problem. Local MB shops probably use Valvoline G05 anyway and it may come in a MB bottle at twice the price according to my research.

I am resigned to using the yellow coolant.

 

Great news, everyone! Grip-grip was able to pin down an intercooler for me, and with the expert help of Steve, the car was finally reassembled today. Car started right up, and has been running like a champ since. I took it for a ~150 mile drive and pulled over a few times to make sure everything was buttoned up properly, and saw no signs of and leaks. So, the car appears to be ready for the private event this weekend.

I searched for G-05 coolant and couldn't find a local joint that carried it (didn't think of Valvoline until I read this thread). So, I ended up buying two jugs of the Mopar HOAT red fluid... Same stuff as the MB Blue, and likely as expensive. Blue wasn't available, but I'm not picky on color as long as it's approved. Will separate IC system from engine system in a few days, but wanted to simply get everything together and running today.

 

Congratulations... back in the saddle. A couple of great buds you have there.

 

Understatement of the year, Anthony and Steve are priceless.

 

i couldnt figure out why it took 6 hrs to install the i/c and s/c. then i came home removed the front seats, deleted the rear seats, installed the 4 point rollcage and fixed my rear view mirror in about 3 hrs. NO JOHN! having all my tools in one place helps also! glad to see you back on the road homie looking forward to this weekends racing!

 

Hey, truckdriver....don't be trying out that roll cage....here me.....lol:cool
And, now that you all have confused the crap out of the old guy, can I mix the G05 yellow coolant with my blue... I lost a little installing my separation kit on the roadster awhile ago. Trying to get ready for a weekend in Chi-Town....

 

I'd like to think I'm a decent enough guy.

By the way, can you pull the AIT sensor and let me know if all is well?

 

From my knowledge the answer is yes, you can mix different colors of HOAT but not different types like OAT and the rest of the types.
The only difference in what you have is the dye in the coolant. Add a lot of Zerex-05 and you will get green in the tank.

 

I found Preston Dex-Cool supposedly for aluminum radiators with the additives. I can't find the blue at all....

Well, at this point, I guess it is time to just drain it all out and pick one to put back in.....

 

DO NOT USE DEX COOL it is an OAT coolant and there have been lawsuits over it. It makes sludge in the system. Use an HOAT type only.
Dex-cool Contamination

 

That's what mine looked like last year when I put in my catch can... guess I'll R2 the intercooler this winter... Mo money Mo problems. lol

 

How many miles on yours? Also, are you running separated system?

Cheers,

 

When doing some research Dave, I read the same article. I didn't use the OAT...I just need a quart to top off what I had. Once I get down to the MB dealer, I will order enough of the new MB gold to flush and do both cars...should last my life time...lol

 

I'm at 88k mi now. Found that mess around 84k. Separated system since maybe 55k and running a Ford lightning pump since 15k mi (basically same as stock).
