Overheating problems

[5.0_GT_kid]

UPDATED @ POST 12​

Alright, so here is my problem. I'm driving home from Lakeland last night after dropping my girlfriend off at her college. On the way, my upper radiator hose developed a split, but I made it home before the car got too hot.

Today I replaced the hose and went to drive back to lakeland to see her, and after less than 5 miles the car was already getting close to overheating, so I came back home. The funny thing is that the car never acted sluggish or started pinging.

Does anyone know what the deal might be? Did I forget a step in replacing the radiator hose that might have fouled everything up? Any and all suggestions needed.

maybe theres some air left in the system

Ok, how would I fix that problem?

A haynes or chiltons manual has info on getting air out I believe. Can't get my hands on the book right now, but I'm sure its there.

Maybe a search on here will get you info. Pretty sure that info is here, but maybe not.

If air is not the cause, maybe the thermostat is not opening. If it hasn't been replaced in a long time, it might not be a bad idea to replace it.

I'm gonna flush the coolant and replace the thermostat tommorrow, hopefully that fixes it.

I'd replace the thermostat like Car Nut mentioned, but I agree you probably still have air in the system. Park the car on an incline or put the front on stands/ramps so the radiator fill is the highest point of the system when you're filling it. That should be the easiest way to ensure the air gets out since it'll want to find the highest point.

Just a friendly tip... If you're going to the store tomorrow to pick up a thermostat, check your lower radiator hose before you go. If your upper hose split because of old age then there is a possibility that your lower hose may be ready to fail as well. Why not replace it while you have the system down.

Did you remember to refill the radiator and overflow bottle after you replaced the hose? I am 100% sure you lost a great deal of coolant when the hose split.

I checked the lower one and it seemed ok to me.

Yep, I refilled both.

When I burp a system, I generally do as Matt outlined but then let the car idle with the rad cap removed. You have to be very careful of hot coolant spewing out. You can renew coolant as air is removed. You can also see when the t-stat opens and coolant starts moving across the coil.

Good luck.

Ok, today I replaced the upper radiator hose again (the new one i had gotten had a slit in it, replaced free of charge) flushed the coolant system, replaced the T-stat/gasket with a stock replacement.

I had the front end of the car jacked up and let it idle for a few minutes with no radiator cap so the air could escape. I took the car around my block 2 times and when I got home the temp gauge was already on the "A"

What is so weird is that the when this all started, my car got so hot coming home on the bridge that the check engine light came on, but my car was never pinging or acting sluggish.

Any ideas WTF is going on here?

When I purge air, it normally takes 20 minutes or so. I let the car idle long enough to have the T-stat open (this is when some decent air comes out). Otherwise, if air is still in there, the ECT reading can be off, which means the fan doesnt come on, etc.

Good luck.

Ok, I'll try that.

 

[sade04]

when im letting air out of the system, i usually squeeze the upper rad hose a few times. i dunno, doing that usually gets the air out pretty quickly.

 

[5.0_GT_kid]

Ok, I'll give that a shot as well.

mine did something similar found out the fane control was no good check to see if fan comes on check connections first maybe water spraying on it hurt it
