Rodding Radiator Survey
I have a plugged radiator and am considering having it rodded out but am hesitant because I was told that many times its just produces lots of leaks.
I would like to get some idea of the success rate in rodding out radiators Please share your experiences with me - basically have you had this done successfully or did it just cause leaks? If many have successfully done this it will make a difference in my decision. Thanks. |

Re: Rodding Radiator Survey
If done by a radiator shop it should be fine. I've had several done over the years.

Re: Rodding Radiator Survey
I have successfully rodded Model A radiators. However, there are some considerations one must take into account. If there were a lot of pin hole leaks going in, rodding will only make matters worse. EPA regulations have closed down a lot of old school shops and most techs only can use a plastic weld gun to R&R a core. Too, a lot of shops used to pinch off a tube and not worry about cooling. However, on an A radiator, that would look like crap.

Re: Rodding Radiator Survey
Repeated success in the cleaning of Model A radiators may be compared to dental technicians cleaning teeth ...... some hurt and some do not ....... then, they all differ from office to office and from town to town.
For your particular area, maybe get telephone numbers of a few used car lots, or tractor dealers in your area where used dirty radiators are usually located on a used vehicle. Then ask who would they recommend to clean vintage radiators. The very last thing a used car business would appreciate is a radiator shop that hires anybody off of the street who screws up costly radiators ...... and/or ..... charges too much for a bum job. Meeting with the technician with Model A radiator in hand, just ask if he feels comfortable performing this task ....... if he has gray hair or balding, it is a plus. Hope this helps to not have to buy a new one. |

Re: Rodding Radiator Survey
Unfortunately one cannot always tell how thin the walls of the tubes are. When rodding them out it is possible to split a tube. My opinion is that if all else fails then try rodding. Worst case toy need a new core, but if everything else did not work you need a new core.

Re: Rodding Radiator Survey
Tom Endy recommended I have mine rodded many years ago, and at that time he knew an older gentlemen that used to have his own radiator shop, and then was doing them in his garage. I took my radiator out and took it to him. After it was done, he told that there were over 20 tubes totally clogged, and he was able to open all but a few. My car then ran much cooler, and has never overheated after that. You need someone very experienced to do that properly, without damaging the tubes, but it can be very worthwhile.

Re: Rodding Radiator Survey
You can try filling it with lye for about 1/2 hour and back flush good. You may have to do it twice. Remove the radiator first and wear protective clothing and eye protection.

Re: Rodding Radiator Survey
This isn't rodding but thru my 77 yrs I've used 1 part muriatic acid mixed w/ 8 (or less if you're brave enough) parts water w/ radiator removed , then flush in about an hour or sooner if the mixture is richer .
As mentioned above , success depends on radiator integrity . Wear rubber gloves & don't inhale the straight acid & by all means don't use it on aluminum as it dissolves it . This also works well removing aluminum from a steel cyl wall that has been scuffed by an over heated alum piston . Just carefully wipe on the acid being ready w/ a wet rag to remove it . Then oil the cyl . Last edited by 1Tudoor; 02-09-2016 at 02:04 PM. |

Re: Rodding Radiator Survey
Two weeks running vinegar, followed by a four day soak in evaporust (out of the car and turning everyday to ensure total coverage) worked wonders for me.
Just be sure to neutralize the vinegar in the rad and block using dissolved baking soda, a full box or two should do it. Flush the block real good too, after the vinegar when you pull the rad and turn it over, back flushing with the fill cap over a bucket, you will get tons of crap, the bucket catches the chunks so you can see it.

Re: Rodding Radiator Survey
I've had several done at an old school radiator shop. Worked out great.

Re: Rodding Radiator Survey
This is my opinion ,. if you find a radiator shop that will rod it out for you
and do it right then that means one tank has to come off anyway ,., so I would get it re cored while I was at it and not worry if it is old and rotten ., Unless you are dealing with an old school shop these guys I dealt with called putting the radiator in a heated vat for cleaning / rodding When I said you have to take off a tank to rod they said oh we don't do that ., If you are having trouble , save yourself some grief and go ahead and core it ., and be done with it ., ., .,

Re: Rodding Radiator Survey
I've had several rodded over the years with success. If you're in Southern California, try Toms radiator shop in the city of Orange. Good work, nice guys.

Re: Rodding Radiator Survey
One (1) past, non-Model-A experience with a vintage radiator:
Have a (4) cylinder 1947 Farmall Cub Tractor that I acquired about 16 years ago. This vintage model tractor has a radiator fan but no water pump; however, warmer water rises and circulates like that of a Model T Ford. When I got it, it had a very minor leak in its "original" radiator; and when I saw radiator tubes were not very clean, I asked around for a very reliable radiator shop, removed radiator, and brought it to a one-man shop in a rural area. Radiator gentleman did a marvelous job and carefully rodded it out for $40.00. This (68) year old radiator still works great after being rodded out (16) years ago. |

Re: Rodding Radiator Survey
I use to repair radiators after people did this sort of thing to a radiator. Would have been so much easier and cheaper to bring it in first and have a "Qualified Radiatorman" look at it and figure what needed to be done. Instead of trying it yourself and ruining a good top tank and possible a radiator.

Re: Rodding Radiator Survey
I've only had rust, never grease, so the vinegar works well. It is also very slow and easy on the metals and doesnt cause massive destruction.
did this to my 12 Buick and a few model A's-both rads and gas tanks. Also have done motorcycle gas tanks and the tanks come out like new. When you get your heart worked on, you can choose invasive surgery, stints and cleaning of plaque buildup, or you can choose drugs only. Depending on the condition of your heart and your situation. The vinegar is less invasive and there is less chance of blowing out the rad as is possible with a rod. fastroadster hits it on the money. I would never endeavor working on one of my pocket watches-neither the patience, tools or knowledge. |
