air in radiator lines?

[Steve Wood]

It would have been a hole that you drilled in it...not sure how well they work on a Buick because I noticed the holes I had drilled in mine were pretty much blocked by the housing...

hmmm. Ok.

So, i ran the car up to 183 and i never seen the fluid get sucked down into the radiator.  the hose going into the water outlet did eventually get hot, but it was way after the 180 mark. My fan also didn't kick on.

[phil_long]

And, the car was full of fluid. the fluid that filled up in the resovoir had flowed back into the radiator when i made it home.  my mom said when she got out the car earlier, the coolant had pushed up to pass the full mark. it wasnt past full last night when i drove it though

I got it fixed. I forgot about that fan connector i had to fix before i sent the car off.  Just fixed it. fan came right on at 197, car warmed up to 203, dropped back down instantly to 190, and the fan turned off. SO we good to go

[Steve Wood]

Need to fix that connector...or by a new one from Caspers and replace it...much ado about nothing.  Nice when it turns out to be simple

Im going to replace the t-stat though because it's not opening until about 200 or so. Got the car out this morning, and it ran up to 210, then never went above 200 once it came back down to 190. i enjoy learning. so would you all recommend a 160 or 180?

180 or 190 only.
Where do you live?

[Steve Wood]

I prefer 160 or 180, but I have doubts at the moment about the 160's quality

the problem with the 180 is that your new chip programs the fan to come on earlier so it will run more than it needs to.  I am sure Eric can fix it for you if you request it.

Before you change the thermostat, put your new injectors in and the chip and see how the temperature acts.

Above 180 is too hot.

Lol. Im in Saint Louis!! Thing is, with a sticking T-Stat and a fan that's not designed to run until 197, I'd expect temps like that.

Got it.

[Steve Wood]

remember that your fan is not coming on until 197 so there is nothing to keep the temperature below that other than the air flow thru the radiator when you are driving.  So your temp is going to be higher than it will be with the new chip

Also, I often notice that the first time the thermostat opens in the morning, that it goes higher than it does the rest of the day...

Nice. I'll keep this in mind my good sir. Thanks

And, the car run so good now, one can only wonder how well it's going to run with this TT chip and injectors!!

[Steve Wood]

It should have better drivability..s moother at all points....and if you can run more boost, which you should if the fuel pump and hot wire are good, then you may have another 20-30 hp
