So I did a head gasket repair last weekend with the pour in stuff. Since then my truck is overheatiing within a half an hour. Replaced condensor fan. No change. Replaced thermo. No change. Don't know where to go next. My only vehicle for work and it is stressing me something bad. If anyone knows what I need to do please email me or even feel free to call. I have go to get this thing straight over the weekend. My name is Jack and the number is 919-791-8213. Feel free to call between 0630 and 2200. Thanx brothers. Happy early Fathers Day to those of you who have children.

 

That bottle stuff is terrible for the cooling system. What brand did you use?

No heat and overheating sort of makes me think you had a blockage in the radiator and heatercore and the sealer in a bottle put the cork in it, so to speak.

Drain the cooling system and flush it with a radiator flush, try and get as much as that crap out. If it worked it won't need to stay in there anyways.

 

First question I have is why did you overheat enough to the point of damaging the engine? Do you know what failed and did you fix it first?

Liquid cement at the cost of $10 to fix a repair that requires you to pull the heads, have them checked and machined, replace head gaskets and misc is no where near comparable.

Do it right the first time and save money and headache you have now. I'm sorry. There is no other way around it if you heated it to the point where you blew head gaskets. You at this point have damaged the heads and hopefully nothing else.

 

First of all I wouldn't call that a Repair, at best you bought a bit of time before you have to replace the head gaskets. At worst, you signed yourself up to replace the heater core and rad as well as the head gaskets.

The overheating could be from the head gasket still, I'm not convinced that is properly repaired. Tough to tell from your post, but the subject makes me think you aren't getting any heat out of the vents either? I'm guessing your heater core is plugged up, I had an old Dodge Daytona one time that someone decided to use that stop leak stuff, when in reality all he did was sign me up to replace the heater core cause it plugged that solid, but the rad was still leaking as bad as ever.

What I would do for a repair is as follows:

Pulls heads and replace head gasket properly, inspect heads for damage from overheating.

Completely flush cooling system, including heater core and rad.

Fill cooling system with coolant and burp it of any trapped air pockets.

Run truck and check for overheating. You may get temperature swings until the air pockets are gone, but it shouldn't overheat. If it approaches overheating turn it off, let it cool down, and check your coolant level, it probably needs topped up. You could also prime the heater core, by removing the upper line, filling it with coolant until it is full, and reattaching the line, I had to do that to a 318 that refused to burp itself.

If the truck still overheats and you have all the air pockets out, check for flow through the rad, and possibly replace rad.

Once overheating is fixed, check for heat from vents, if you don't have heat from them, tear dash apart and replace heater core.

And the last step, throw whatever you have left of that stop leak away, and never look at it again.

 

Well I dont think that I blew the head gasket first of all. Had some leaks and went about repairing them the wrong way. Stupid idea. The truck was not overheating before the liquid bull**** however. I am fluching the rad today and going to perform a block test on it to ensure there is no blown gasket. Hopefully not. If anyone could please give me a call I would greatly appreciate it. 919 791 8213. Thanks

 

You're going to need to do a compression and leak down tests to narrow it down to a busted head gasket or not...

You plugged up the system somewhere... I'd never in a million years use that liquid stop a leak crap... you really should take those heads off, replace the head gaskets and flush the high hell out of that coolant system with coolant system cleaner.

You might even need to replace your radiator, water pump and heater core if it clogged them up as well...

 

So flushed the system out with cleaner and water. Pulled the upper and lower hoses and flushed through in both directions. Water flowed good after the initial blast. Heat runs really well now and no leaks to be found yet. However on the way to work she overheated again. Dont believe the water pump is out as I can see the fluid moving in the rad. Dont need anymore comments about the stop leak **** just advice on what can be causing this issue. No smoke out the back so I still do not beleive the head gasket is blown. Will be testing it this evening just to make sure though

 

You have likely clogged your radiator. It may not be fully clogged but I bet it's partially clogged.

Do yourself a favor and run a CHEMICAL COOLANT SYSTEM CLEANER through the system and flush it again....

Don't leave the cleaner in there too long or it will eat away at the radiator from the inside, so follow the directions to the letter.

Just because there is coolant "flowing" does not mean that it is flowing at the correct pressure or being cooled effectively by your radiator.

You need to clean and flush the system from 8 places.

1) Upper Radiator Hose - Through Radiator
2) Lower Rad Hose - Through Radiator
3) Heater Core Line 1 - Through Motor
4) Heater Core Line 2 - Through Motor
5) Heater Core Line 1 - Through Heater Core
6) Heater Core Line 2 - Through Heater Core
7) Upper Radiator Hose - Through Engine Block
8) Lower Rad Hose - Through Engine Block

Also I hope you're using HOAT Certified Coolant (should be Orange)

Last thing I would do before putting fluid back in it would be to replace the thermostat with a BRAND NEW one.

If you still have problems with overheating after that you need to replace the water pump.

If you replace the water pump and it still overheats then it's time to pull the heads off and take a look at what is really going on.

 

Replacing water pump tonight. Flushed everything with the cleaner like you said already so thats gotta be what it is. Fluid no longer appears to be flowing.

 

THERMOSTAT... Don't forget to replace that too!
