'91 Loyale overheating
Posted 03 December 2012 - 03:11 PM
The past few times I have used it the fan has not ran and the car would overheat if idling too long, but if I ran the heater I could keep the temperature close to normal and then once at highway speed the car was ok. I had decided that I would bypass the fan thremo switch so that the fan would always run and was waiting for a nice day to do that.
During all of this I have checked the exhaust for any sign of coolant smell and so far nothing there. I've had head gaskets go on a couple of GLs over the years and it was usually easy to know when that happened.
Yesterday I had to make a quick trip to town. This time she ran hot on the highway, and even with the heater going I could barely keep the gauge out of the red so I turned around and headed for home and planed to hot wire the fan.
When I got home I noticed that the top radiator hose was hot, the lower hose was barely warm, and the fan was not running. This morning I put the thermostat on the stove and it opened just before boiling, so I figure it is OK.
So now I am thinking I probably have a radiator that had been gradually becoming plugged. Does this sound like it could be the problem?

Do you have a secondary car you can use by chance?

You can get a cheap radiator for 45 bucks on ebay. I have one in our Loyale that has been problem free for over a year now. Free shipping on it too.
New radiator, new hoses while you're at it. Thermostat wouldn't hurt. Good luck!

I had to drive in to town to buy a new thermostat gasket so I decided to pick up a thermostat while I was in town. If I want OEM I would have to order one, so I just bought what was available.
I aimed a flashlight down into the radiator and it is looking rather slimy down there so I am thinking that is the most likely problem. This thing has been coming on gradually over the past six months. I should have a relatively warm day later in the week so I plan to drain the radiator and see what comes out.
I have a radiator here that I took out of my old 85 GL. They look the same, but some sources show it as compatible, other not. What do you guys think? If it fits and the engine runs normal I would not see it as a permanent solution. I'd still order a new one. But this old one is here, now.

I found a new radiator on Ebay for $60 so decided to buy it instead of messing around with the old one out of the '85.
