Hi Guys. I am hoping someone might have some insight into what is going on with my new setup.

I got the ProCharger installed - all is fine, the SCT box tune from SCT. When driving, if I stay even footed, the engine stays at a normal operating temprature (staight up and down in the 05 GT gauge). However, if I give it any gas and rev the RPM's to 4000-4500, the temp goes up to full "overheat" with-in a second or two. If I coast and/or slow down , it goes back down.

Now, the fan is running, and I refilled the fluids. The only thing I did weird was I used 100% coolant instead of 50/50 mixture coolant and water. I don't know if this would cause an issue.

Anyone have any ideas ?

I don't have a procharger but straight antifreeze is not recommended. Can gel and cause other issues. Was the antifreeze premixed or straight? Possibly an air pocket when you refilled the cooling system.

 

Ya mustangs (since 96) are pretty notorious as bein harder than most cars to get the air worked out of the system after drainin them. I did heads on a 97 cobra and had to 'burp' the car for bout 2 hours to get it all out. It was the same, idling and cruising it would be fine, punch it and bam, overheat.

 

run 50/50 water/antifreeze. the water takes away the heat. the antifreeze is used to lower the freezing temperature of the coolant and in the summer, raise the boiling point of the water. i think the ideal balance between water to antifreeze is something like 57% water to 43% antifreeze. but 50/50 is easy to compute and measure out for everyone and close enough to do the job. antifreeze also incorporates some anti-corrosive properties into the system too i believe.

remember, taking away the heat from the engine is the water's main task.

about your gauge, i have no idea though. i haven't heard of that. the fact that the fan kicks in would lead me to suspect that the engine is in fact getting hot to warrant the fan coming on. i'm not too clear here. does the fan always run now? or does it turn on only when you rev her up, then when cruising at lower rpms turn off?

 

Normally, my 'stock' Temp gauge reads straight up and down when at normaly operating temp.

BTW, you all confirmed what i was thinking. I figured this was the issue but was in such a hurry to get the ProCharger going I over looked the obvious - to use the correct ratio. I will redo the fluids in the morngin and let everyone know the results.

Thanks for the feedback.

Besides the mixture be sure and check for a air pocket. I got one in my 04 Cobra and I almost overheated it

Can't wait to hear what you think of it

 

Bryan I would be very careful and correct the problem before serious engine damage has be done. Excessive heat & aluminum (heads & blocks) don't mix well. An air pocket is most likely your problem. Worst thing about an air pocket is the temp. gauge will not indicate a problem until it's too late. Remember a temp. gauge sending unit can't read steam. By the time the superheated coolant reaches the sender and the gauge indicates an overheat condition the damage has already occurred in most cases.

The 100% antifreeze is also definitely a problem. However 100% antifreeze will cause the engine to gradually overheat because straight antifreeze can't dissipate the heat as well as a 50/50 mixture of antifreeze & water. Eventually straight antifreeze can gel and cause the tubes in the radiator to be come plugged preventing coolant from flowing through them.

Lastly on the driver's side of the engine, (just behind the upper radiator hose connection) the coolant manifold has a plug in the top. I have looked at that plug and thought that by removing the plug the trapped air could be released as it is the highest point on the engine. Figured I would try it the 1st time I have the coolant drained. Perhaps someone else can chime in and confirm or deny this.

 

Hey Bryan, if I remember corectly the manual also stated that an incorrect antifreeze mixture could affect the sensitive water temp gauge sending unit...That might have played a part in your gauge's surging. I hope you get it resolved.... Keep us posted.

 

i would check your coolant hoses, they are tight on the 05 when you install the procharger, and make the changes to the coolant system, i would also check to see if the thermostat is pointed the correct way

look for collapsed hose that runs to the oil cooler, to the tstat housing

 

Update Guys:

I drained the radiator - about 1 gallon of pure coolant. I then cranked the engine, and went back and forth from 'burping' the hoses and filling water (1 gallon). I did this until the engine was at normal operation temperature and the entire gallon of water was used. I then test drove the car for about 20 miles. It remained at normal operating temperature the entire time.

Thank you for the great feedback, it saved me from melting my engine.

BTW, the ProCharger is FREAKING Great!

Man Bryan,
I can't wait to see it. Glad it worked out for you.
I wonder what kind of numbers you are putting down now.
Are you going to do anything to the Trany?

 

The only thing for the Tranny is just the shift mods that SCT has provided. And, holy crap, does it shift hard now. So hard for 1-2, 2-3 and 3-4. Wow!

If it blows, I will just have to wait for a better built one

-Bryan

 

byran, are you going to the dyno anytime soon to see what it does and do some fine tuning? if so, where are you going to go, H.P.E. or that new place.

 

Man, Bryan - I am SOOOOO jealous now! Bet your car screams! I'm really looking forward to your typical detailed feedback on the ProCharger on your Mustang page...

 

Here you go guys, my write-up:

I am going to a quick dyno tune for the current 6# pulley this Thursday. This is just to make sure the A/F is correct so I can go WOT. When the upgrade pulley and boost-a-pump come in from ATI, I will go for a full tune/dyno and invite everyone that wants to come see it

-Bryan

 

Cool, I can't wait.
It's been awhile so I'd love to see what everyone has done to thier Stangs.
