Cold Case radiator

[Doubeleive]

It's cooler out today and on the way to work this popped up. Temp gauge was at the bottom below 160. Surge tank is full. Does this radiator work too good? I'll be checking the temp sensor when I get home. Top radiator hose was hot but I could hold it without burning myself. Cold side of the radiator was just above ambient temp I'd say.

the return line to the reservoir is too large you need to install some kind of restrictor to make it at least 1/2 or more the size/flow it is now, too much coolant entering the reservoir messes the system up. maybe go to the hardware store and get a reducer in the pipe section and insert it into the return line.

I'll give this a try. Thanks!

Classic symptoms of a failed coolant temp sensor. Easy fix. If it takes you 10 minutes, you must’ve stopped to smoke a cigarette.

I could be wrong the larger return might make it run too cool instead of hot, can't remember which.

Too cool.

Somewhere in these threads a 45 cal Brass without primer installed was cited as a "perfect"fit restrictor.

I used the nipple from the old radiator as in insert in the line to get the restriction.

I tossed the old radiator already but I have plenty of brass casings so I'll try that.
I know it's not the temp sensor because after driving around a while it must have got hot enough for the warning to go away and the temp came back up to 210.
