Running warm...

[93reddroptop]

What is the best way to get my 93 to cool better. Besides checking for restrictions/filter problems. It seems to run very warm nearly pegging at 260 degrees. Any ideas?

New thermostat, and vent cap for the radiator. Make sure your overflow tank hose is not leaking and the level is properly filled.

I had this same problem.....I took the top support off my radaitor and found that the space inbetween the radaitor and the condensor was full of leaves.....
I have no idea where the leaves came from....they are now making a shield to cover the intake area and I am thinking of putting one of these on....
What Nitronick says it realy happens

Did you verify the operation of your coolant fans? I know my car hit close to that once, but the fan wasn't working.

I could hear the fan kicking on. I had this issue this summer but I was assured by people on here that they tend to run warm and it was normal. My problem was last week when I had i had luke warm air blowing after a long drive. I had it out in 25 degree weather and the needle was pegged nearly. Is my thermostat messed up perhaps? The thermostat is a stock one should I perhaps replace it with a 160 degree one?

Are you saying that your heater isn't putting out much heat? If so then you could be low on coolant. Check the things that craig mentioned. You may have an airlock in the cooling system, not sure how it is done but you may need to bleed it.

If you are not getting much heat out of the heater, you need to make sure the control valve isn't stuck. A little more trouble is the temperature control lever(assuming you have the manual unit). I am going to have to dig in my dash and repair the cable. It was stiff the first couple of times I tried it, and one day it got real easy to slide all of a sudden!:duh

It is possible there is an air pocket in the system, but I would think that would lead to a jumping temp. Kind of like an erratic type of thing. I believe there are bleeders are you cars. For me I just run it with the radiator cap off. If it gets really hot, in cold weather I think there is a problem. Your thermostat might very well be stuck closed. There are some simple things you should check, like fan, thermostat, air pockets, and proper level of coolant.


Good Luck

Yo, fellow cheeser!

You can check your coolant and flush, replace as necessary, with probably a 50/50 mixture. That kind of temperature though, leads me to think that there is more, like the accumulation of debris mentioned in the link.

If those are in order, and your fan(s) are coming on (is this only while sitting or also while driving?), you can have your radiator cap checked at a decent parts store. You can check that the thermostat is opening by grasping (with care) the upper radiator hose to see if the coolant inside is getting hot, when appropriate.

I think the 160 is too cold; that 180 is as cold as I'd run; preferring Robert Shaw over Stant.

The bubble-while-running (without the radiator cap) bleeding works on my car, but I don't know the 93's.

Come to think of it I bet it is the coolant level. I'll have to check into it after church. It would put my mind at ease. LOL. Here I am wishing it was spring already. It's been in my garage for 3 months already....

I have the automatic control unit with the push buttons on mine.

Ok. But it still has the door under the dash that controls the hot/cold air flow. It should also have the hot water valve under the hood(passenger side by the heater core. Don't know on the '93 model). I just know I wasn't getting ANY hot air with the temp gauge sitting at 200. I got out and gave that valve a push with my finger, and the heater almost burned me out of the cockpit
First thing, though, is to make sure you are full of coolant. And if it has been driven a while and not checked, pull the upper radiator cover off and look at the cavity between it and the condensor. It only takes about 15 minutes.
