so i went into my garage to go clean my engine bay from dust/dirt and what not. I look down my and my ic coolant is totally not full its empty. Me knwoing nothing about ic pumps or coolant stuff i call firestone (i know a buddy there) and take it in to get it filled. nicely those guys helped me out free of charge and their time. They would fill it up and it would hold and fill up but they told me to take it around the block and i would come back and it would be empty.... now i am not over heating but when they put it in i was reading 200+...

now my question is.... is the coolant suppose to be full in ic coolant resevior (sp)?

No leaks at all no intercooler not anything !

 

Option b or fill neck?

 

The LSJ has two separate cooling systems. The DIC coolant temperature readout is your engine coolant, not your IC system coolant. The only way to monitor the IC coolant temperatures is by logging IAT1/2 via interceptor gauge or HPTuners.

Engine coolant temps around 200* is perfectly normal, especially while idling...cruising is normally between 175*-190*.

So back to your issue - you're filling the h/e system from the cap directly in front of the s/c, correct? And after a bit of driving, it's empty? Sounds like you have some air pockets that are slowly getting worked out. Get a gallon of distilled water and fill it up...drive around, fill it up again, repeat. Please also make sure you have a working IC pump.

If you know 100% your IC pump is working, and you are still losing coolant/water mysteriously, you may have a leak in your laminova cores...this is very rare though. good luck.

 

okay i was at idle so thats explains the temps what would happen was he would pour in the dexcool and it would filter down and we kept poring it in and it would filter. Then finally it filled all the way up. im pretty sure my pump is working becuase i squeezed the hose and it swirled. 76k and still worked pretty happy. but anyway they filled it i kept driving it would empty. but im guessing ill keep filling till it stops? they were talking about air bubbles

 

best way to fill it (if on stock h/e and no optionb) is to slowly fill through that filler neck in front of your s/c while its running until you have coolant steadily flowing through the neck. if coolant isn't moving ur i.c. pump is out

theres no coolant leaking on the ground right?

 

no thats the first thing i checked was holy **** am i leaking SDFJSDFKASKJ
but i wasnt thank god. i mean the coolant filtered through the right side when they poured it in. for some reason when the coolant was just sitting there in the neck it wasnt going down. thinking it was full i went and drove popped the hood it was gone. i did this a couple times.

 

that's wierd man. if its not flowing in front of your eyes with the key on, your i.c. pump is out or going out. tap it with a hammer a few times then continue filling.

really though its a sealed system and shouldn't be low unless u have a leak

 

Stock tune + key on = IC pump not on. On stock tune the car must be running for the pump to flow.

 

oooh thanks didn't know that! haha thats a nifty little feature to add with a tune

 

so there should always be coolant in the neck??? im positive there is no leak i even put paper and stuff under too see if it did but nothing... and if it was there would have been a huge puddle im guessing... is it bad that an ic pump doesnt work? i beleive mine is but i am at work not and cant check i know you check by squeezing the hose


btw i had my timing chain kit replaced recently could that be linked to why all that timing chain stuff failed somehow?

 

Yes - It is bad if the IC pump is not functioning. There is usually coolant in the filler neck at all times, and when you release the cap, you may hear a hissing sound from the pressure the IC pump has built up.

To check for a functional pump, fill the system completely and put a straw in there. Turn the car on. If the straw moves to one side, the IC pump is working. If there is no flow, your IC pump is bad and the straw will not move.

 

awesome thanks a lot for your help! one more thing if i kept pouring coolant in and it kept filtering down does that mean my pump is working or is that but becuase it needed more in there... i have been running without coolant filled to the neck (when i got my chain replaced they refilled my coolant fluids) for awile without any problems or over heating. im not saying if my ic pump is bad that i wont replace it

 

you simply want to keep filling until fluid stays in the neck (but the fluid should be moving, ofcourse)

you wouldn't know if you were overheating unless you have been monitoring your IAT's (intake air temperatures). like hockeyman said, your coolant temps displayed on your d.i.c. have nothing to do with your supercharger manifold coolant temps.

 

okay cool what problem could occur if the pump wasnt replaced i bought this car off the previous owner in december of last year im not sure if the pump is broken or not yet due to me at work but if it is broken it must have been broken for awhile....

 

The car will not perform well, to say the least.

 

worst case scenario you are heatsoaking your blower and increasing chance of knock in your engine. you want your intake air temps to be as low as possible to perform well, go fast, and last long.

a new i.c. pump is around 100 bucks from zzp and takes ten minutes to replace, super easy. that said i'm still not sure if your pump is actually shot or not thats up to you to figure out by filling her up and seeing what the fluid does

 

That's so weird my car seems to be performing fine with no coolant in my neck. I'm just confused but yes I did see that zzp sells them the cheapest I will buy one once I get out of work and see if there is any flow in my neck after I fill. Hoping for the best

 

Nono dont buy one yet, like i said

While ur car is running, slowly fill through the filler neck with coolant/water.

Until you cant get any more in there.

If the fluid is moving through the filler neck consistantly, you are good to go. Without cooling flowing through it, the i.c. System is not working.

If the fluid is up to the top but not moving through (left to right by the way) then your pump is not working.

Go under the car and right behind the heat exchanger, on the block (fton side, bottom, closer to.drivers side) there is a pump with two hoses coming from it. Tap it with a hammer a few times to see if it frees up the pump.

It may work for a while if not replace it then.

 

Oh no no haha I wasn't going to buy one immediately I was going to fill first. It seems to filter down when I drive and I have to keep refilling maybe air pockets like hockey said

 

Yeah thats what im assuming. It doesnt fill very fast at all. Like you can only get in about a cup at a time

I bet the previous owner gad someone flush the coolant and emptied the wrong radiator lol

 

Sad thing is this had 76k I'm sure this was empty for a while. My whole timing chain went bad I am wondering if this was a factor...

 

That i dont know. Wouldnt hurt to try and meet some local ss guys to check it all out. Does is seem stock?

 

I am going to the Ohio meet Saturday and its 100 stock nothing is done. I am getting it fixed up first before I mod performance wise.

 

If the intercooler pump is broken the coolant will get very hot in the cores from sitting there and eventually evaporate out of the system.

 

That might have happened to mine ill check tonight
