Overheating

**RUSH2112** · 05-01-2007, 10:22 AM

I am having a problem with overheating. Just had some work done over the weekend. New rad hoses all the way around and I don't see any of them leaking. New thermostat too and it is dry around there also. The timing is off for sure so could that be causing my overheat.

Other work included installation of a cobra upper/lower intake.

Here is a pic of my temp guage. It is just barely dancing with the redline and stays there constantly.

yes the timing can do that. My buddy did that to his old foxbody he used to have

**RUSH2112** · 05-01-2007, 10:37 AM

Ok. Funny thing is it doesn't really seem to be idiling bad. Just about 900 to 1000 rpm, which is where it idled before the installation. I think the guy said my timing was at 0 or something. I know he did have a problem with the distributor cause the TMI module was hitting the intake preventing him from turning the distributor or something

Also, I can smell the anti-freeze (sweet smell) a little bit. Not sure what that means?? Could my heater core be leaking??

gaskets??? Are you using any oil?

**RUSH2112** · 05-01-2007, 11:13 AM

what about gaskets? I have always had an oil burning issue.

you head gaskets might be popped but first check to see if he did your stat right

wait you might have an air pocket in there

do you hear any gurgling?? possible air in the heater system... have you put your heat on since the work was done???

could be a bad stat and not opening at all or in backwards.....

**RUSH2112** · 05-01-2007, 11:20 AM

I am pretty sure the stat is correct. Don't hear any gurgling per say.

The head gaskets are probably OK as well.

On the trip home (3 hour drive on the PA TPK) the temp guage was perfect, even up and down the mountains

Had the heater on defrost this morning. It was blowing hot air

good info...does it get that hot even when moving....

when a certain shop tried giving me my car back mutiple times, twice it was getting hot like that from the HG's not sealing properly and blowing exhaust into the coolant..... have you lost any coolant??

No. the rad is completely full and has been since Saturday. THe overfill is 1/2 full and stayed the same.

The heads were never taken off, so I am not sure why the head gaskets might be the problem?

you have an air pocket behind yoru thermostat that is keeping it from opening. I had a coolant pressure tester from autozone i borrowed for free, all i did was pull the hose off your heater tube that goes to the throttle body, then put the pressure tester on the radiator, and pumped it VERY SLOWLY to let the rest of the air out. if your smart you'll put the hose into a bottle so you don't run coolant all over your car.

Ok, sounds reasonable. How do I fix that?

**billyNOTnice** · 05-01-2007, 11:53 AM

If your timing is at zero i'm pretty sure you car wouldn't even start. what type of intake are you running that won't let you turn the dist? and why would they make an intake like that? Has your mechanic ever worked on a mustang before, because something seems way off here. you should have no probelm getting your timing set you have some sort of super custom intake i believe, I may be wrong though. Also, if you just want to change your idle, all you have to do is turn your idle screw down and you'll be just fine, as long as you don't close the throttle plate the whole way.

you could try what i said, pull that hose off and try that, it worked for me, but may not work for you. Not sure if anyone else has any ideas, but you might just have to pull the thermostat back off, then seal it back on. not really a big deal, takes like 15 minutes if you've got a lot of stuff blocking you up.

The intake is a upper/lower cobra intake. The dist does turn, but the TMI hits the t-stat housing. I'll try the bleeding technique you mentioned.

**billyNOTnice** · 05-01-2007, 12:08 PM

i've never ran a cobra setup, but there is no way you shouldn't be able to get your timing set correctly. i mean they manufactured these on cars

**Stangman701** · 05-01-2007, 12:59 PM

Sounds to me like the dist. is just one tooth off. You should take it back to them and have them install it correctly. If they lift it up and turn the shaft back a little than put it back it you should be able to adjust it correctly.
