Coolant question here.......

[5.02GO]

I installed a new 2 row radiator with a 180 stat on my lx. The temperature was running really hot. Sometimes touching the top green slash on the temp gauge.

I tossed the 180 and put in a 160. Just a slight improvement.

Yesterday, i purchased a 3 row radiator. I still have a 160 stat in it. Car runs a little cooler about half way on the temp gauge.

For my motor, thats still rather hot.



In the past, when the motor got a little warm, i would drive down the highway or on a country road and the motor would cool down. That doesnt happen now. The only thing different that i can think of is the coolant. I used the "new" 50/50 premix prestone stuff.

Has anyone had any similar problems like this?

You are using a real gauge? The system was burped?

Good luck.

I second the real guage. You can get some sunpro's at the auto parts store for $30 or so. Get oil pres. and water temp. I use manual guages only. Fact is you have no idea how hot it is.

Yeah stock gauges arent real reliable for telling the truth. Get some sunpro's or if you can get some nice autometers.

I am using the "stock" temp guage. I know that the gauges may be a little misleading. The guage was reading alot lower befor i changed radiators and coolant.

Burping....

I really didnt do any burping that i know of.

Umm....I had the jack stands under the front end when i added coolant. And started the car with the cap off of the radiator and let it run until it started pushing coolant in to the bottle.

Isnt that the way you get the air out?

thanks.

Are sunpro's really reliable? Moreso than stock?
BTW, "burping", as I understand it, is squeezing the upper radiator hose to make sure that there are no air pockets in the upper hose. This can be done while the car is running with the cap off the radiator. You might see air bubbles "burp" in the radiator opening, then the level will sink a little bit if there were air pockets.
Anyway, Sunpro's --I always thought they would be junk!?!

To start out, your issue was the fan, not the radiator. Either get an electric or a new fan clutch and new fan if the old one is cracked. If I were you and going to stay with clutchfan, I would look into a HD clutch and the FAL metal fan.

Now your having radiator issues, and it probally is an air pocket. Does the heat work real good? If so then the air pocket isn't in the core. If it isn't that there is probally air in the core which is common.

I really don't know much how to help from this point over the net.

to burp the cooling system take the cap off the radiator when its cool and start the car then squeeze the upper radiator hoses lightly and it should burp the cooling system to get any ait bubbles out of the car
