The reason I ask is because I'm in the process of building a remote waterpump with a meziere pump. In order for me to use a thermostat I would have to build a housing for it which isn't going to look good and I'm going for show more than anything on this. Can I just hook up a relay to one of my water temp gauges that has output signals for cooling fans and power the pump with that? Have the pump turn on at a certain temp?

 

I don't believe in it. I have never run one with my setup and never had any problems. The way I look at it is that the fans do all the deciding on how cold or hot the car stays so who cares about the thermostat. Besides it's just one less thing to worry about the way I look at it

 

you don't have a problem with the car taking for ever to warm up?

 

your electric water pump must run at ALL TIMES.
if the coolant doesnt circulate continuously, pockets of very hot coolant will develop, your temp gauge is only located in one place

jesse

 

my car didnt have a thermo when i first got it...

if i drove it to long no mater if both fans were on, it just couldnt cool the water

as soon as i put the thermo in there it stayed at about 200* and didnt have that problem again.

and yes it took my car about 10 miles to get to about 180*

 

wait, you're saying the car ran hotter with a thermostat? Is that right? A thermostat is closed when it's cold and opens when it's hot. Running with no thermostat should be the coolest way to run the engine. Right?

 

Sort of, It will just take longer for the coolant to get up to temp. Once it's there it will stay the same as with a stat. Say for instance you have a 160 stat, that's when it opens, and if it's like my car that runs at 190 in the summer it stays open. Some say the minor restriction the stat offers will slow the coolant flow down so the air flow going thru the rad will cool the coolant more efficiently. That's crap. NPG told me to take the stat out, plug the hole in the waterpump that recirculates the coolant back thru the block with a core plug. Unfortunately it didn't make a difference in my case.

 

NO!!!!!

Having no therrmostat will cause the coolant to run through the radiator too fast, resulting in poor coolong of the coolant. It will stay warm, and when it reaches the engine, it will be too warm. Get a 160* stat. My temps stay at 170* at all times, unless I am stuck in in Phoenix traffic for a bit in July when it is 120* out.

 

i dont know, i have to agree with him, use a 160, i dont know about not having one at all... =/

 

so pretty much if I had something in the cooling lines that will stimulate the restriction of a thermostat, I will be ok. I'll just have a hell of a time heating up the engine on cold days

 

Word.


I personally recomend either a restrictor plate rated for 160* or a stat. DO NOT RUN WITHOUT EITHER!

 

Where do you live? That's what the profile is for. I don't drive my car in the winter. In the summer it would take about a 1/2 hour to get up to tenp. What I stated before was an experiment. I now run a 180 stat, which causes my engine to run at 204*. Heat equals power as long as it doesn't cause too much timing retard.

 

All you people that say don't run without a stat. Is this something you heard or something you tried. I would think it is something you heard, because I have tried it, and there is no difference. Kinda remind's me of the people that badmouth the G2 CAI, something they heard.

 

Something I tried with my thirdgen, heard in the field and on this forum, and learned in school. Basic knowledge really. It doesn't allow enough time for the radiator to do its job.

 

Oh and I agree with ya anaik, there are alot of forum "techs" out there .
