91 2.6

at first the car would chill at just above 80 more and more frequently began running up to 100.. i pulled the thermostat out and it still runs up to 100+

no oil in water no water in oil

fan clutch is good just rebuilt it

running straight water right now

i know the coolant return hose (top of t-stat housing to coolant expansion) is a bit clogged i didnt think this was EXTREMELY important maybe it is?

water pump seems to work fine

no leaks.. im stumped!!

help? =(

Replace or clean out hose,, and why in the world are you running straight water??? That is not good for a variety of reasons.

I run just a little above 80 in my 89 2.6 and thats with an 88* thermostat I do believe. So it probably runs maybe 90 or 91. And yeah running straight water is not a good idea, even if you do live in california.

ok so today..

i picked up a new hose from tstat to exp tank.. picked up some radiator flush and flushed out a goo ball of copper that was wedges in the heater core. simple? doesnt stop there..

flushed it through and found out why there was a copper glob apparently the water pump seal has a tear and it started leaking.. back to kragen..

picked up some knw nanotech cooling passage sealer ran it through at idle for 30 minutes as stated on bottle no more leaks, cooling system now cools instead of boils.. gotta let the passages dry out over night tonight and refill fresh in the am.. car runs at a cool 80 flat now im super stoked it wasnt something god awfully expensive either

and on another note this is temp for work this week but my water pump i ordered just cause of that one leak will be here midweek wen ill tackle the water pump replacing all seals and bolts accordingly.. this car is fun and surprisingly just as simple as a chevy

The lack of coolant and straight water could have caused the issues. First the coolant is a form of lubricant , and second it is a corrosion inhibitor.
To add sealer is not the best of moves, as you may find the heater core will not be as effective, and all you are doing is temporary fixing things that had seepage or leaks (possibly caused by just water).
Time will tell if something decides to spring a leak.

Not trying to be a doomsdayer here, but water was a bad idea. It would be a death sentence in northern climates.
