ah very true.

C) You have/had a problem with yoru cooling system (water pump w/pulley)

Is your accessory drive system in good shape? You don't have an underdrive crank pulley or something like that on there, do you? Or a bum idler?

You can certainly try a thermostat. They are cheap and it's one thing to remove from the debug process.


hmm that all makes sense. sorry bill but i have no idea what any of those are...im sort of a n00b when it comes to real technical stuff, i just now the bare basics.

sweetbmxrider 03-16-2009 06:40 PM

he means smaller than stock crank pulley or an idler puller, one that simply spins and does not turn an accessory, that is hanging up or putting extra strain on the motor.

basically it seems the belt is not being spun fast enough. very good observation on Bill's part

My 70 SS396 has a 160 t-stat in it and it will run at 160 in the winter which leaves me with very little heat in the car. In the summer it will run at 180-200 depending on if I get stuck in traffic. But that's a mechanical clutch fan and you should have electric fans that can turn on sooner. Try the 160 and see how it runs. You need a restriction to slow the coolant flow, but you may still have another issue like too much timing or clogged passages. And don't even try to compare to a 93-97 LT1, they are reverse flow cooling so it's a totally different scenario.

Nope, I've owned 2 LT1 cars and have no complaints about them. Mine actually ran well and passed inspection on the rollers at DMV and one with a supercharger! But you can't offer LT1 cooling advice to non LT1 cars.

ok i will try that tomorrow. definitely no clogged water jackets, when me and my buddies took the motor apart over the summer to replace the head gaskets checked all of them, they were clean.

madness410 03-16-2009 11:53 PM

will pop a thermostat in tomorrow and check to see if it makes a difference. thanks for all the help again fellas.

i put in a 160 thermostat and it still overheats...i knew it wasnt going to do anything. next stop is the waterpump because the whine is getting louder and louder by the day. but jeff you are saying something about too much timing? can you explain that?

madness410 03-18-2009 07:54 PM

chris from nj also suggested to bleed the air out of the system...i will try that before trying a new waterpump.

JL8Jeff 03-18-2009 09:39 PM

If your timing is advanced too much it will cause the engine to run hotter. Are you sure you don't have any type of underdrive pulleys?

not really 100% sure...as stated earlier im not too advanced with cars i just know the basics...i was wondering what they were though

LTb1ow 03-19-2009 07:28 AM

Well take a photo of your crank pulley...

JL8Jeff 03-19-2009 12:38 PM

I don't know 3rd gens well enough, but I'm assuming it has electric fans. Did you check to make sure the fans are spinning the right direction when they are turned on? Make sure they are pulling air through the radiator and not pushing it from the engine compartment forward. If somebody messed with the wiring maybe they could have reversed them by accident. Other than no coolant circulating, you really shouldn't have a reason for it to start to overheat just sitting there if the fans are working right.

madness410 03-19-2009 12:45 PM

yeah after I think it's the water pump it may not he circulating correctly. I
will post pics of the pulley system later

LTb1ow 03-19-2009 01:08 PM

It has oil right? Does it sip antifreeze or oil?

what do you mean lol...i put oil where theres supposed to be oil, antifreeze where there is supposed to be antifreeze. i may be dumb but im not retarded haha

madness410 03-19-2009 06:47 PM

update: bled the system out completely and thoroughly, got it up to 200*. went at ate dinner, came back down drove it around it sat at 180-190 most of the drive, which is a lot better given the fact it didnt climb above 200 when driving, it was also cold air outside.

when i parked it in front of my house and sat there for 3-4 minutes it hit 200 and was climbing still. i picked up a water pump from jersyboyy and will most likely be putting it in over the weekend...unless there is another simple step i can take before i start ripping stuff apart.

here are some pics of the pulley system

call the photo police...i suck at taking pictures...

madness410 03-19-2009 06:48 PM

another thing any and all help is greatly appreciated so far everyone has led me to the correct direction. i feel like im really close to solving this problem and im set for spring / summer

JL8Jeff 03-20-2009 07:19 AM

How is the fan attached to the radiator, I don't see a fan shroud?

madness410 03-20-2009 10:12 AM

yeah its an aftermarket radiator. the fan is attatched by a cooling mounting kit...picked it up at advanced. they slip through the radiator fins and can be secured by placing something on the other side.

its like that
