How to fix a clogged radiator?

Just about every major city has at least one and usually several shops that specialize in radiator repair. They remove the "caps" or "tanks" of the radiators and run a rod through the small tubes. The process is called "rodding" the radiator. The parts are then dipped in a solvent and cleaned again. The radiator is then re-assembled and you are ready with a radiator that is like new. Some of the newer radiators, with the platic cans are not as suitable for this process. Also, the brass radiators can be soldered if there are leaks, making them somewhat more desirable. But then, some of the newer radiators seem to keep going for a long time, so it's all just a crap-shoot.

How does transmission fluid get into radiator cooler?

Nope, a dealer said my radiator was "gone", and that transmission fluid may have mixed with the coolant, and they have to flush the tranny (180 dollars worth of tranny fluid) to ensure it is ok, add a new radiator, coolant, and a transmission filter, plus labor and you get 1100 worth of work-is this accurate?

Yikes...

yes a tranny flush is expensive (@ between $150 and $200). Plus, a new radiator. So, I'm afraid it's possible. But, they're killing you with labor costs. Just make sure that your car can handle a flush. In some cases, mostly in older vehicles, a true flush on the transmission can cause it to lock up, rendering it useless. I'm just taking a guess here, as I don't know what your driving, so I can't even guess how much a new radiator is for your car.

1991 Ford F-250 7.3 diesel radiator capacity?

If the information I found is correct, the '91 F250 diesel holds 4.3 to 5.3 gallons of fluid... You are suppose to use the DIESEL type antifreeze/coolant, found at "truck-stops" due to the "calcification" that can build up inside the engine... Using regular AF/C "will" work, but only to keep the engine running...

The proper AF/C only needs to be changed once every 50,000 miles or 8-years, whichever comes first... If using it for towing or heavy loads, it may be advisable to change it more often...

I also have this type of vehicle, and found out this week, the previous owner only had water in the radiator, which may explain why it's so hard to start in the cold, 45 degrees or less...

How do you 'burp' the line after replacing the upper radiator hose on a 1997 Cavalier 2.2 with no radiator cap?

Assuming you didn't drain the system, you shouldn't have to burp it at all. Just keep the reservoir full and warm up the engine. it circulates through the reservoir and back to the radiator.

To "bleed" the cooling system on a 1997 Chevy Cavalier, there is a small brass bleeder valve located on the heater pipe that runs along the front of the motor (metal pipe). Open that valve a couple turns and pour in the antifreeze in the reservoir tank until antifreeze starts dripping from the bleeder hole. Tighten the valve, but be careful not to tight too tight, they are soft brass and break easy. Finish filling the reservoir to the Full Cold mark. After driving the car at least one time and letting it cool down, check the antifreeze level on the reservoir and fill as needed.

How do you drain the radiator of a 2001 Chevrolet Malibu.?

Just below the radiator lower hose is the petcock. Unscrew it partially and it will drain. It has a "T" type handle that does not require any special tool. Be sure and save as much antifreeze as you can. If you do not reuse it then take it to a repair shop or AutoZone so that it will be disposed of properly.

How do you remove the cover on the radiator on a 2001 Ford Focus?

It is a real pain. First you have to take the fan shroud off. It clips in 4 slots on the radiator two are snapped in. Pull on the tabs and then push up and remove the fan shroud through the bottom of the car. This will give you access to the radiator. The radiator support has 4 bolts that need to be removed from the bottom. Then it takes some moving around to get it free, the whole radiator slides to the left. It took my friend 3 hours and he is a mechanic, they really bury the radiator on this car. It comes out from the bottom the plastic that you see on top isn't how you remove it.
