not the water pump, not the thermostat, what is it???

EDIT:not the fan either, and water circulation is good, radiator not clogged

 

please halp meh

 

dont ask for help in the for sale section go post in the 2nd Generation forums.

 

holy crap my bad, i jus clicked 2nd gen specific, didnt know it was in the FS section... can a mod move my post please

 

come on its simple right

 

the only thing you didnt name is air in the system lol so check that are you sure the waterpump belt isn't sliiping?

 

i doubt air in the system, no idiot buzzer, i dunno, its not even my car, and this dude says he did check all that ****, i guess could be, ill have to check tomarrow....

EDIT: belts good, no slipanagationizing

 

What kind of fan are you running? A lot of electric fans cant put out as much as the stock clutch fan. Overheating at stops?

What about the heater core?

 

stock clutch fan, heater core bypassed... you think that could be why? the heater core is bypassed on my fc and it doesnt overheat

 

My heater core was so old, when I went to either take off the hose or putting the new one on, It created a small leak in it. It was actually barely dripping down the firewall

Find a cooling system pressure tester, that is the best way. Your coolant levels good?

 

coolant level is superb, and greener than ****

 

A tempurature gun to check the temps at thermostat, before and after radiator, engine block wouild be nice

 

i could see the coolant gettin sucked down when we started it, doesnt have a thermostat i guess... anyways i put more water in after it went down and capped it. so, the water pump works so im assuming that its going through the motor right??? and the radiator is fairly new he says...

 

did you open the top of the radiator before filling? if you didnt, it wont allow coolant to go in the engine fast enough

 

are you using a mazda thermostat?

 

How about a blown coolant seal??

 

i opened the top cap, started the car, then it got sucked down

 

no thermostat

 

no

 

Still working on that post count?

Don't bump your post on the tech section.

 

why not?

 

haha you need a thermostat im sure that has something to do with it

 

yeup, if you dont run a thermostat, u run a restrictor plate

 

yea put a thermostat back on there.

 

you need a thermostat in there. it restricts the water flow for a reason, otherwise the pump just cannot pump that much water at once, and you end up with hot spots in the motor. If the tstat doesn't fix it, by next best guess would be a plugged rad, but i'd be willing to bet its because you have no thermostat
