Hi Guys,

On each side of the radiator at top tank are 2- 10 mm head machine screws holding the "condensor coil" for the A/c.

Am I correct that these 2 connections are not ALL that is holding the coil, just added as supports from the radiator?

Once I remove the top hose, bottom hose and remove the 2 shrouds then I will gain access to the auto trans hose connections, and removal of the screws atop the tank for the "Coil as previously mentioned I will be able to pull the radiator up and out. Another words no screws at the bottom out of sight connect to the radiator to the coil.

Please advise
Thank you

It sounds like you have removed everything needed. Won't it come out?

Dear jacob and Nick,

I was writing first about the details because I noticed the 2 straps on top for the coil asking if there were any oter coil attachments that would prevent easy removal.

So do you agree that I have the steps correct.

Thank you

Hi:
Without being there I can't be 100%, but from what you described, it sounds correct.

Engine Cooling problem
2001 Hyundai Elantra Automatic

My radiator blew out and I decided to change it myself with the help of my brother. We chaged it and thought everything was fine but then the car started overheating very quickly, blowing cold air out of the heater settings, and revving up the engine in two seconds cycles (that is it revs it up it comes down it revs it up down up down u get the picture). I came back to your site did some research and thought that maybe there was air in the line, we followed your instructions to get the air out but the car is still doing the same things. Please Help.

Hi luckyme0428,

Thank you for the donation.

When engine is cold, did you check the radiator coolant level at the cap?

If level is full and overheating occurs, did the fans start working?

Did you test if the radiator fans are working?

When the radiator blew up, the engine could have overheated and damagd the thermostat.

Do initial check first before going to thermostat test which would require removal of it.

Let me know what you find out.

I did check the radiator coolant levels at the cap.
The fans did start working.
And since my first post I changed the thermostat.
But the car is still overheating.

When fans are workings, do they stop intermittently when temp gauge shows high?
Is air blown through the radiator very hot?
Do you need to top up coolant after running engine?
Is coolant being forced out to the reserve tank?

No the fans do not stop intermittently.
I dont know about the air being blown hot. (I'm afraid to let the car get hot again).
I do need to top off the coolant after runing the engine.
Coolant is being forced out the overflow tank.

Situation don't seem optimistic.

Engine is overheating and pressure buildup in cooling system.
If the radiator cap had not been replaced, then it could be bad. Check the seals for wear or tears.

If the radiator cap is not the problem, you have blown the head gasket caused when the radiator blew.

Check for water contamination in the engine oil and get a test done for hydrocarbon leakage into cooling system. Ther should be a kit available at your local parts store.
