Hey guys whats up? Ok heres what is going on, Nathan helped me tune the car well he did it and i watched but now i am over heating. i think it might be timing. because it is spiking on the logger around 38* timing i put a new T stat in and it helped bring in back down to 247 when it was going up to 265. Any Ideas?? sorry for the hap-hazard.




Thanks Guys

247* is near catastrophic meltdown. Do a compression test, see if the headgasket is gone.

for real ^^^^^

At part throttle cruise your timing should be 35-45 degrees. Part throttle acceleration should be 10-25 degrees. 38 is pretty normal when you get out of it. Like they said, check the head gasket. Your timing is still what I would call extremely safe for your boost level.

i looked and watched the fan thats on the driver side its not turning on at all could that be it?

The driver side fan only turns on with the AC. If your other fan is turning on you're golden as far as fans go.

How hard is it to do a head gasket i have never done that before and how long does it take.

Make sure you do a compression test first. You don't want to jump into a headgasket job and then it not be your problem.

If you have to ask, make sure you have some help for your first one.

i was having overheating issues and it was a tiny pinhole leak on my heater hose.. make sure you go over your hoses...
also you can wire up the ac fan to run at the same time as the other without the ac on. a good idea if you plan on doing any track time

Ok guys i have looked, there is not a coolant leak. No where, i park the car in my garage on a tarp its been sitting there for the last few days and nothing would drip from it.....

Ok so what do i look for next. The radiator cap the rubber on it has allot of cracks and tears on the seal part. Could that do it. If so why did it just start doing this after tuning. it would not just tear from better tuning would it.

None of this happened till we started doing the timing on the car. Why would messing with the timing and the fuel cause it to do this? and how could i fix it ??????

All Ideas r welcomed


Thank You

I would imagine if your cooling system is losing pressure through the cap that could be causing it. I would get a new one and see if that takes care of it. They are only a few bucks if i remember right, so no harm no foul.

Do a compression test.

Comp Test what does that normaly run "$" to have done?

Free if you know somebody with a compression gauge. If not you can pick one up at Autozone for about $20.00.

How hard r they to do???

no harder than changing your spark plugs.

Very good info Black!!!

Um i Just put went over all the hoses tonight for coolant and did not find any at all then i started it and it started to go up to 230 just by idling so i put the rpms up to 3200 in park. and it went down to 213 and then back to 217 just jumping around there when i gave it some more rpms. Help i dont want to spend alot of money on this guys i just had a baby 2 weeks ago i am just try to get it up and running and sold UGH!!!!

Check the oil again to make sure it's not milky.

By running it while it's in this overheating state, if it is a headgasket you're taking a chance of ruining the engine. If there's coolant in the crankcase, it'll ruin your bottom end letting it run like that.

BEST THING TO DO is change the oil and do a compression test. I'm sure the new owner is going to want to know the results of a compression test if they buy it.

Is the water pump moving water??

Take the rad cap off and see if water is flowing through the system, if not pump could be toast and only is moving water at higher rpms.

This may be obvious but if you perform black92_tsi_awd's suggestion make sure you do so on a cold engine or you could end up with some burns and a mess.

welll i did that and started the car after i put more coolant in and it bubbled out .


um?

Definitely sounds like a blown headgasket but do a compression test to be sure. The coolant shouldn't bubble out. It should flow through the t-stat housing. Bubbling out makes me almost positive that you are losing combustion pressure into the water jacket through a blown headgasket.

amen!
