Auto parts stores sell radiator cleaning solution, made for cleaning out the coolant system.

Can your transmission pick up dirt from your road and transfer it to your radiator?

No, I haven't heard of that method. How are you going to get the radiator to fit in the glass on your nitestand?
Seriously though, if that radiator is original, it probably needs to be replaced. trying to clean it will just open up the holes the corrosion is plugging up.

I would pull the radiator and have it tested for leaks in the bottom transmission cooler tank, and if that's what the radiator indicates is wrong, replace the radiator.
 
Don't waste your time trying to clean out a badly clogged up radiator with additives, IMO.

#619 of 629 Troubleshoot 96' Grand am 3.1 v6 Thermostat by monkey4hire

Dec 29, 2010 (11:13 pm)

I'm Having trouble changing out the thermostat on my 96' grand am. It has a 3.1 v6 in it. I have so far removed most of everything that is in my way; however, there is a small black bar that is preventing me from getting to the housing units two bolts. Any Ideas?
 
- I have taken out the battery, air ducts, and loosened the big mess with the brake fluid spot to have room. The small black bar is just in the way enough that when i put my extension on, it lays just off center enough were it won't turn the whole bolt.

#620 of 629 2000 Toyota Camry cooling fans won't turn on temperature gauge is going up by mtnes

Sep 12, 2011 (11:56 am)

Good morning,
2 weeks ago, I was in a shopping mall for at least 45 minutes. I came out to the car and saw the greenish puddle under my car. I wasnt sure if it came from my car so I had my daughter move the car to a different parking spot. I opened the hood and noticed that my coolant reservour was empty. I called my husband to get some coolant, we put some on the reservour and we went home. We checked it again and it was empty and the top of the radiator had some of the coolant leaking. We figured, we needed a new radiator.
 
Here's all the things we have done so far...
Last July : brought it in shop for overheating - new timing belt and water pump and check cooling system. It was okay until 2 weeks ago
 
Last week:
Replace radiator
Replace 2 (big) hoses top and bottom
Replace thermostat
Replace the harness wire that connects from the temperature sensor to the right cooling fan. We had to replace it because we broke it when we were taking it out. there were 2 wires and one of them came off. Ordered that through Toyota dealer.
Put in new Coolant anti-freeze coolant both in radiator and coolant reservour
 
Started the car and let it idle, temperature gauge is midway from COLD and HOT
No leaks
The 2 cooling fan starts to work when A/C is on
The right cooling fan turns on when we disconnect the harness wire connected from the temperature sensor to the right cooling fan.
Both hoses came hot.
 
After 30-45 minutes, The temperature gauge went up slowly. I was told that when the radiator reaches a certain degree, one of the fan should turn on... none of the fan came on at all.
 
I don't see any switch for the fan - green wire that is near the thermostat. What did we do wrong?

Well, many cars have a trany fluid cooling radiator as part of the overall radiator. In other words, lines go into and out of a radiator, carrying tranny fluid. There is a small, separate radiator for the tranny fluid inside the radiator.
 
If there is a leak into this tranny radiator, you've got big problems. Pull the tranny dipstick, and see if the tranny fluid looks ok. It should be red, usually. If there is any foam, or looks like water bubbles on the stick, the coolant if probably leaking into the tranny coolant.

The cooling fans of my 1996 Plymouth Grand Voyager SE won't come on, which is the cause of my car's overheating, even after I have replaced the fan relay, thermostat and coolant temperature sensor. What could be the real problem?
