car still overheats

I'm not saying it should run that hot, just saying that it won't hurt it to let it climb to 215 or 220 to see if it levels off or something like that.

i havent pressure tested the system...you mean the coolant system? not quite sure what that means.

so despite it steaming up i should let it run to 215-220 to see if it stops?

[sweetbmxrider]

i wonder what the condition of the coolant is. maybe its an improper mix + older coolant.

[madness410]

yeah im going to do the water pump after i test out the fan with the shroud...i cant really find the time between work and school so this thread is going to drag a little bit.

adam i use the 50/50 coolant from advanced...it was all new when i swapped head gaskets in august...when i bled the system out i lost maybe half of it and put more of the same stuff in.

[camaroAL]

coolant mixture isnt going to give u a prob. most racers, including myself run straight water, and if i left my fan on it will run at 150-160 no higher with no t-stat. sometimes too low of a number t-stat is no good either. also a low pressure rad cap may help as well. try to get a 7lb lever lock one

[madness410]

arrite i will see. i think i have a lever lock on there right now. watch...all this and its going to be something really stupid..i can tell usually it always is with this car

If the car is just sitting and idling and you turn the electric fan on, it should start to go back down pretty fast. A mechanical fan will try to keep it around the temp of the t-stat or the lowest the combo can run. It sounds like your electric fan isn't working well enough by itself so try the shroud. If that doesn't bring it down then the fan itself is a problem or the coolant isn't circulating properly or could be geting aerated by the pump.

I remember him saying something months ago when I first saw the car about the previous owner putting in an aftermarket pump and how we all contemplated it being the wrong direction flowing pump. He changed the radiator flushed the system used good coolant its either the pump or he didnt bleed the system and its got a bunch of air bubbles in it.
Just what Im thinking is going on...we shall all find out soon enough..I hope, so when are you going to do this thing?

[sweetbmxrider]

i couldn't imagine there is still air in it as much as he drives unless there is other issues causing air to get into the system.

[DevilDougWS6]

pressure test your system. the pressure tester looks like a pump with a hose on it, you put it on your radiator fill neck and pump it up to a certain pressure (whatever it is for cars, hmmwvs are higher)

if the needle holds in place, then there is no problem. if it falls then you have a leak somewhere, where air is getting in.

i just took the pump out today..ran into a few problems...the bolts on the water pump were pretty much superglued in there, no idea but they were the hardest thing to get out, and by the time i went to pick up the waterpump gaskets i ran out of daylight. it will be finished by tomorrow. i appreciate everyones help. thanks again.

1st collect parts
2nd take off parts
3rd drink beer


see, you're doin it wrong!

[madness410]

see adam thats theory number one.

theory number two is what i subscribe to. my theory is im so sloppy at doing work on cars that im going to need to run out to replace parts, or get more of whatever i need, so while im there ill buy the parts i need. haha.

one time when i was working on my civic i beleive i went to advanced auto like...3 or 4 times in 2 hours. the people working there were like: or

I always end up smashing stuff up, or getting pissed and throwing old parts across the garage ( like the old window motor lol ) which usually results in a trip to teh local pepboys for **** that got thrown that wasnt supposed to.

hahah same i was doing spark plugs with my buddy on his stang and they wouldn't thread in so i spiked it an shatter the porcelain there are many other times **** happened as well haha

[madness410]

what the...the new waterpump i bought off jerseyboyy was off an 87 trans am...and doesnt fit the pulley that was on my old water pump? IDK. couldnt find a replacement pulley on it. i went to advanced picked up a brand new one off an 89 and its the same as my old one. im painting it now and its going in...

i was working on it today and an older guy drives by with his kids and wife in a mini van...hes like: YOU SHOULD HAVE BOUGHT A FORD!! in my head im like, this guy doesnt know what hes talking about...then say: guy im pretty sure this is better than any ford you have ever driven. he said he was kidding and he had an 88 iroc, and complimented me on my TURD gen.

sucks to get the image in my head but i will probably be that guy someday yelling that to a kid whose working on a 2010 camaro 20 years from now...

just an update..

i think im really close to fixing this problem. i hooked the new rad that i have up and the fan set up, also put on the new water pump i bought. i filled the rad with coolant, left the cap half on because i wanted to check it as the car was running, turns out that was a big mistake. i turned on the car hung out by the hood for a few minutes...and the temperature rocketed to 210...so i turn the car off..and the radiator cap goes FLYING and coolant spills out everywhere from the radiator all over my lawn. me and my friends have never heard of that happen before...anybody know? im guessing the pressure built up a little under the cap, and when i turned it off it released the last of the pressure and exploded off.

so im like, cant let that happen again...i top off the radiator with coolant, seal the cap and start it up. it was at 200, went to 185, shot up to 195, then down to 180 or so where it sat for about 5 minutes until i turned it off. i didnt want to open the cap when it was hot so im going to let it sit and check back tomorrow. but if it doesnt climb when its idling thats exactly what i set out to solve and it didnt do it today...so hopefully i fixed the problem ..knock on wood.
