Someone tell me if I did something wrong or am going to?

[illest3rd]

When I installed my SR i was running the stock sr radiator that sucked @$$ it looked like I was growing turds in it it was so backed up. SO to keep the car from overheating one of the things I did was remove the thermostat. Car was still running hot but driveable. OK so neways my first question is the timing was done at this hotter temperrature so that means its gonna run richer then normal right? Then I bought a Koyo radiator and now im having the opposite prob the car never heats up cause I have no thermostat what little heat it manages to build goes away as soon as I start driving. So I plan to put in a new thermostat this weekend. Then I was thinking I should redo the timing after I have that in and it sitting at a good average temp. Am I right? and also should I change the sparkplugs before or after all this cause I imagine they are fouled a bit?

that sounds like the dumbest thing i've ever heard anyone do


you REMOVED your thermostat because your car was running hot?

why not...flush your coolant system out? get a new radiator?

Nope nothing wrong there.

While you're at it, drain all the oil out and run it hard at high revs for a few minutes, nothing like finishing off bearings and ringlands that are scored from not reaching operating temps.

I would love to see an example of an engine that suffered damage from a thermostat being removed other than overheating. I've seen it done a million times without anything wrong. It should be just fine.

ehhh b4 doing that I did flush the cooland system out, even used some acid crap that I bought the was supposed to clean it out. Nothing workged The radiator was garbage . . even thought there were bubbles and spent hours trying to get all the air out of it . . . . The radiator itself was crap and until I got the Koyo I just left the thermostat out. I know it wasnt the smartest thing to do but seeing as it was running hot and it did help I was a temporary fix. Can I get my original questions answered?

The timing was done when the engine was running hotter . . it wasnt like . . on the H or anything but it was maybe one space above where it should be so I know if the timing was done there its probably wrong. Right? and should I replace the plugs b4 or after I do the timing?

In hot weather, you may never see it. Try driving in 40 degree temps like that. Cylinder wall tolerances aren't within spec when the motor is running 100 degrees colder than normal.

dude im in Tx. . . its not like its snowing over here, were sampling hell right now its hot as fuck

[the head]

removing a t-stat will decrease thermal efficency and cause many issues put it back in.

well he wasn't running 100degrees lower than normal.. he took it out because it was running hot... now it runs a "little warm" without it.. with the koyo it runs cold and yes that can possibly lead to a long term failure but he's putting a thermostat back in this weekend... so since his motor never ran cold how is it screwed up.. other than the couple of days after the koyo install which won't hurt a thing. The cylinders are still warm it's just the radiator is dumping excess heat into the enviroment and not running at it's peak temperature. As for adjusting the timming. I would check it but it probably won't need much of an adjustment and changing the spark plugs won't be necissary. 210f is warm/hot... I doubt he was running anywhere below 150f with the koyo and no thermostat... it'd suck in the winter because he'd have NO heat and the engine would be really cold but in the summer should be just fine. No worries mate

simply amazing... how old is the car? or should i say WAS

[NismoSilvia270R]

I always thought removing the thermostat would help overheating, since the coolant/water is always flowing and doesnt spend much time in the radiator. Thats with a stock, or clogged, rad

With the koyo i can imagine quicker cooling and under temp conditions.

either way, not a good idea to remove thermostat. next time turn the heat on, sweat your ass off, and save a car.

[sideview_180sx]

if the water/coolant doesn't spend much time in the radiator, how can it transfer radiant heat efficiently to cool the motor. usually no thermostat blows when trying to warm a car up, since thermostat would be closed to allow the engine to warm up. search on FA for more info. besides you might need a new water pump. if it is failing it would not be able to cool effectively even with a koyo rad. use some of that domestic racing stuff to flush out the build up in the water jackets.
