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.
Don't waste your time trying to clean out a badly clogged up radiator with additives, IMO.
- 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.
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?
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.

Then I'd expect the lower hose temp to stay cool until after the thermostat has started opening and higher volume of warm water flows into the top but is mostly cooled by the time the water reaches the bottom. Then I'd expect the lower hose temp to start up.
Does the heater inside produce good heat after 3-5 minutes?

Hey, Hoping you can help me with an issue I am having with a 97 Diamante. Problem, radiator fan not turning on. Here is what has been replaced so far.
Fan Motor Works When Jumped To Battery
Replaced Fan Switch
Replaced Fan Sensor
Replaced Fan Relay (All 3) with Horn Relay, All Work Fine
Replaced Thermostat
Only way I get the fan to come on is when I pul;l the connection to the sensor, then it comes on with and without the air.
If I had a gun I would shoot it right now. But since I need it I'm asking for suggestions, Any Thoughts????????
