normla driving for me at the moment the iat's are usually at 105-120 (texas heat) well usually when i give the car gas like -10 vacum the temps will go down... well sometimes now they do and sometimes they dont... so i popped my hood and my opt B tank has more coolant in it then normal.. and its bubbling alot.. i feel all the lines and there is coolant flowing.... and yesterday i leave my car sitting for about an hour and when i get back in and start driving the IAT's are at 150 and i drove for about 10 minutes and it went down to 120 for like 30 seconds then shot up again....

cooling mods are OTTP H/E CAI(i guess lol) and option B

 

Check for kinks and check your pump. Or it could be a simple air bubble somehow got sucked down and now is trapped.

 

i thought option B was suppose to get rid of all that air bubble crap... im pretty sure my pump works cause i can hear it and there is coolant flowing

 

Kyle, I think I know how to get the air bubble out if that is indeed the problem (will need trip to auto zone).
If that is not the problem then you and Jorden probably installed your option B wrong and you should probably go with option C now...

 

gawd alan ur a troll lol.... well were taking everything off again when jorden comes back so we can do my dual pass

 

Idk what you are talking about...

 

My car is acting up to man. I also have the same cooling mods as you.

I'm starting to think my pump is on it's way out. I feel coolant flowing when I grab the lines on most occasions, and on others I can squeeze the hoses and feel no coolant at all. It just started acting up last Friday. It's been driving me nuts!!

 

im already on my second pump i dont wanna buy another... we need a super duper pump lol

 

I just bought a house, and dont have the money for a pump. I'm going to tap the pump with a rubber mallet this afternoon. It is 4 years old now, and prob clogged up from deposits left from the brushes. I'm also going to manually burp my opt. b tank. If none of this works I guess I'll have to pick up a new pump. ZZP sells them for around $110.

This morning I did a pull onto the highway, and my IAT2's dropped nice and fast. The rest of the cruise to work they were perfect. Last night on my way home from my girlfriends they wouldnt drop below 120*F, and my IAT1's were around 60-60*F. It has been driving my nuts!

 

how do u burp the opt b? ill try that as well

 

You gots air in the system somewheres. Just open the vent cap and let the pump run.

 

I open the cap and lift the tank up. Air will travel to the highest point. This is why you want the Opt. B tank to be the highest point in the cooling system.

The Opt. B tank does a great job at bleeding air, but sometimes it is a bitch to get it started. I always manually bleed it to kind of "jump start" the air bleeding process. It has always worked for me in the past. I just don't understand why it has all of the sudden started to act up.

 

sweet thx matt ill do it on my lunch break... advice on how long or when its done ? lol

 

there was no wrong way to install it
hahahaha
but yea we do have to take it right back off to do his dual pass.....

 

awesome man, good idea! we will do this to his car multiple times im sure cause everything on his car takes a lot of effort to get to work hahaha

 

Yeah, thats how things go with my car to, haha.

 

I did the same thing. When i first installed the dual pass and option b nothing was coming out of the bleeder line. I lifted the tank up for a few seconds and then the system started to purge itself own it's own. I'm surprised that none of the how to's or instructions from gm mention lifting up the tank to get things started.

 

I was going to make a step my step how-to for the Opt. B tank back in the day, but never got around to it (i should have). It's a very important step to "manually" burp the system to get the tank to purge correctly on its own. You can luck out sometimes, and the tank will self purge right off the bat, but it's rare.

 

it took mine a couple days to bleed all the air out of it... I would do it for a bit at a time here and there. If the system is making a gurgling noise, then there is air in the system.

 

 

its ok buddy it will work properly soon enough! i would have already known how to do it but i never did opt b on my old lsj.....

 

i hope so... i wanna beat you on E85

 

you will beat me cause my car falls on its face in 4th.....
and you blower is frakin huge!!! hahaha

 

If you have the bleeder line hooked up to the top of your stock HE, then you should not have to do anything. You can try just taking the cap off of your option b tank to let the air out if you want, but you should not have to lift it up or anything like that. I had some IC troubles a while ago which had me questioning whether or my IC fluid was flowing or not. So, I repaced some of the lines with clear hot water heater hose so I could see. Just an idea.

 

time for dual pass
