Engine overheats and heater blows cold air

That is a very hard paragraph to follow.

Is the LIGHT ON, or OFF?

Have you checked for codes yourself yet?

Do you know that you can check for codes yourself?

Do you know HOW to check for codes?

Do you know that when the check engine light is ON, you have a P or Powertrain code has set?

Fill us in with DETAIL, try NOT to run on, and just hit us with detailed BULLETS and break your writing up into paragraphs, please

In one of the previos posts on this thread I did post the codes that I did look up and retreive myself.

-The Light is OFF

-I have the code PCM P0650 Current

Someone told me that code means that the engine light sensor is not working in some way like the wire was cut or it was disabled somehow

I reaserched a little on my own not about cadillac but what that code means in other cars and found that there is a sensor that measures the voltage in the line with the engine light sensor to sense if it actually is on when it is supised to be if I read it right.

I believe all of the lights are supposed to light up when the ignition is first turned on and it appears that they do.

-all lights like abs etc light but there is a gap at the lower right hand side and I can not find the check engine light when I first turn the ignition on.

I am guessing it is eather blown light,fuse,bad conection or something like that that is not allowing the check engine light to light and then sending that code.

I did not clear any codes yet and got a long list.

This is what I came up with When I ran the codes.

No ABS

No AMP

No DDM

No Dim

IPC U1016 History

No IPM

IRC U1016 History

MSM B1820 History

MSM B1845 History

MSM B1860 History

MSM B1875 History

PCM P0650 Current

No RFA

RIM U1255 History

Rss C0592 History

RSS C0594 Current

Rss V1016 History

No SDM

TTM V1016 History

VTD B1009 History

VTD B2734 History

The other code (PCM P0650 Current) I searched around for and found that it was for cruise control (At the time was not working for some unknown reason)

So now that the cruise is working and if I get the problem fixed with the engine light all of the current codes will no longer be present and it should have a clean computer after I clear all codes.

This code C0594 - Right Rear Solenoid Circuit Open

is probably the reason you are getting the speed limit, its not related to the cruise control as you noted, its related to the RR strut I believe, someone will confirm that, I dont have a 2000 manual to venture a guess, but see this, I googled the code, JimD posted there

This thread has morphed from cooling system to suspension (somehow). I'm happy to provide assistance/guidance. Please not not expect me to read all four pages of the thread. :D

I know I could start more threads for each problem I had I am sorry for making it so confusing. Thank you guys for bearing with me and I have already fixed many problems over the last 4 pages and and getting closer and closer to getting things right. Would it be better to talk about the RR strut in a new thread? Just let me know what is better I don't want it to be hard for anyone to give there experience and knowlege. I really appreciate all of the help I have been getting.

You could expect to read more help on a suspension problem within a relevant thread. An (old) "Engine overheats" thread is not going to net many responses regarding a suspension issue. Your choice.

If you do start a new suspension thread, be sure to include the parts replacement (if any) history details and only the related "C" codes. We don't need the module abbreviations; the five character DTC is very specific.

Yeah . . . let's keep it all in one place. Besides, meandering can sometimes be fun.

Is there a fuse for the engine light by its self? or is there just the one for the instument panel? How can I check to see if the bulb is good. The engine light does not come on even when I first turn the ignition on. I just looked in the owners manual and figured out how to get the back seat off but was not able to find a lable for a fuse saying mil. Idk if it would be under another name or not. The fuse on number 6 under the rear seat has a weird metal tab hanging off the left side sticking up. Is that suposed to be there for a conection for testing or something?

Fun; yes.

Productive; ???

I'm home on medical leave right now. Fun is vastly more important to me than productivity. Sorry for the selfishness. Really. :huh:

Thank you for posting that wireing diagram. That got me thinking is there somewhere were I could find a service manual for this car for an affordable price? I think it would be nice to have and I plan on keeping this car fir a while longer and know I will see other issues like one I am having that I have not mentioned yet because I was gonnna wait to get one thing off the list at a time and make a new thread to figure out why my fog lights don't work on eather side when the fog lights fuse is good.

Thanks again for posting that Warren J.

I just googled a wiring diagram symbols guide and went through them all but I could not find that symbol for P101.

nevermind that is a passthrough gromet I guess where it goes through the firewall?

Your service manual describes P101 as "Left hand lower corner of the engine compartment block head, near the base of the strut tower." You can buy a new service manual for $135 from helminc.com. You'll likely find a used one far cheaper on eBay.

Not as good as the factory manual, but vastly superior to what you have now. :D

I doubt that CD is going to be much help. If you can't find a FSM by Helm Inc. on Ebay, consider a subscription to alldatadiy.com. It's basically an online FSM and I have heard good things about it.

Well I was at my neigbors working on the midget and got a phone call from my dad saying he found the problem to the cadillac. I got a little exited/curiouse he told me there was a guizer shooting under the hood from a crack on the rights side of the radiator at the top where it hangs from the frame.

162915_473339079241_637739241_5566853_7764586_n.jpg

I was then thinking no thats not the problem I had before it was never leaking from there haha. It is in its 30's out and im shure it was brittle and had a stress crack in it that gave way when he floored it pulling out of a bank in fear of getting killed by a school bus he said (Sarcasticly).

Meanwhile he tells me I have to drive it like a grandma and it will last. One of those do as I say not as I do haha.

Can this be fixed with some JB Weld maby if scuffed up and cleaned with brake cleaner? How much would it be to get another radiator? aftermarket? or scrap yard.

Thanks

IF that picture is a cracked plastic side-tank, you are NOT going to repair the crack with any JB WELD chemistry.

Bite the bullet and replace the radiator.

Parts only = ~~$150. Parts + labor will be more.

I found one for 151 on this site with free shipping and then I found this one for 164 with alunimum side tanks to prevent the plastic from cracking. I had it in my mind that it was going to be a lot more money than that thats why I was looking for a redneck fix.

Should I go with teh alunimum side tanks for $164?

any tips on replacing the radiator? doesn't look like to hard of a job.

Looks like a pretty nice radiator for $164.

Well, she was definitely due for a change... I'll bet it was original part in there!

What was wrong with it? Did it rattle?

I just changed the one on my 96 deville when I did my engine mounts, it had oily residue around it.

That's no reason to change it.

aah the weak point in these lovely radiators, Believe it or not but on the W-bodys and somee other GMs I blame the Dogbone mounts on the radiator support cracking the Upper pegs. I see it all the time, and it isnt very easy to see the leak because the rubber mount is on top of the crack, no easy fix for that

GM FAN FOREVER

Nice, clean, luxury= fine automobile
