Re: Coolant Temp guage and Radiator Replace?
Modine makes a very good replacement radiator.
However, maybe you could get your's to work longer.
Have you flushed it at all? And, the block?
Good place to start.[img]images/icons/wink.gif[/img]
How old is your thermostat?
Cheap to replace.
A water pump, when it's getting ready to die, will start to show signs of over-heating on the hi-way.
It'll run cool around town, but get the revs up, and the load up, on the hi-way, and the pump starts losing efficiency, heating the engine up.
Sorry, no idea what "N" or "O", or anything else in "normal" on the gauge would correlate to.[img]images/icons/crazy.gif[/img]
Mine hangs right on the "N". 99% of the time.
Incidentally, (gees, I like that word[img]images/icons/laugh.gif[/img]) you can fix that leak in the plastic end tank.
Drain the radiator.
Pull the upper and lower rad hoses.
Tape, tie, whatever, some plastic (zip-loks work good) over the outlets (where you pulled the hoses off).
Close the drain.
Roughen up (sand) the area to be repaired.
Mix up the JB Weld and apply.
Now the trick.[img]images/icons/smile.gif[/img]
Stick your shop-vac hose in the top-fill fitting.
Stuff a rag around it, and in the hole to "seal" it.
Turn the vac on.
It'll help "suck" the JB Weld into the hole.
Only need to do it for a minute, or untill you can tell the rad's under good vacuum for a bit.
I fixed several holes in mine that way, before it completely cracked and fell apart. (Hence, knowing about Modine)
