ok i have a 1995 honda civic sedan with a mini-me swap.
yesterday i put leak-stop stuff in my radiator and now the engine and top radiator hose is getting really hot. and the bottom hose is staying cold.
i just put a new thermostat in it. and its still doing it.
i dont no where the weep holes are but i dont see any water coming out of any holes. so idk... i think its cuz i used that stop-leak stuff.
i need your help to fix my problem!
thx you!

 

You've probably clogged up your radiator. Disconnect it and try to flush it out from the bottom to the top. New thermostat could be bad, the wrong one, etc. You can test drive with no thermostat at all to rule that out.

And as you realize now, don't use stop-leak stuff, fix the leak properly.

 

ok imma do that. and the thermostat looks exactly the same... imma wait to take the radiator out cuz it hot right now and outside...

 

ok well i talked to my sisters bf and hes worked on hondas for like 8 year or more and he told me to gutt the thermostat so i did and now the coolant cycles though the engine just fine.... he has a 89 hatch si... and hes had his gutted like mine for 3 years and his is great!

o and i waz j/w i have a mini me swap and it doesnt have the vtec ecu or the plug that connects to the vtec solenoid. is there a way i can hook it up cheap.

or what sould i do. whats the best way to make it a real mini me swap!

 

Put a good thermostat in. Running without the thermostat causes your oil to get dirty faster, also the ECU will not enter "closed loop" mode which means you will get lower gas mileage and emit increased pollution.

 

i bought a brand new thermostat and put it in, i waited with the car idling for like 45 mins and the engine waz burning hot and the top hose was, and the bottom hose waz cold, it didnt even feel warm at all.

 

This means you got a dud thermostat, or the wrong one for your car, or you put it in backwards (if that's possible in this case).

Also after working on the cooling system you need to be sure to get all the air out.

 

ive looked up how to bleed it. but i really cant find anything on how to do it.
i just drove it for like a hour or so and it got to the "H" hot mark.
so idk this is ticking me off... but i will go to another autopart store and i might just go that my friends off his vtec and see if it works..

 

Did you flush out your radiator? You're saying it overheats with no thermostat now?

Walk away and wait until the engine is cold. Take the radiator cap off. There should be no pressure inside. It should be full to the top. If it's not full, bleed it. The procedure differs whether you have a bleeder screw or not.

If you have a bleed screw on the top of the fitting where the top radiator hose connects to the engine, open it. Pour coolant into the radiator until it comes out of the screw. Close the screw. Put the radiator cap on. Make sure there is some coolant in the plastic bottle.

If you don't have a bleed screw, it helps to park the car on an uphill so the radiator is the highest point. Fill the radiator up. Start the engine (radiator cap still off) and set the heater on hot. Watch the level in the radiator and add more as needed. At some point as the engine warms up, it will start to overflow. Put the cap on then. Don't open the cap again unless the engine is cold. Also make sure there is some coolant in the plastic bottle.

Also when it is hot feel the lower hose. If the lower hose is hot the fan should be coming on. If the lower hose is not hot the fan normally will not come on. You can test the fan by unplugging the sensor in the thermostat housing and jumpering the two wires in the plug (car end). This will make the fan run all the time the key is on. Test drive like that and see if it stays normal temperature.

 

i will find a hill or something to rise the front end. and right now im just use water. and my fan stays on all the time now. so... idk... i kinda think that better anyway... but idk...

and it goes from hot 4/4 to like 3/4 and back to 3/4 on the temp gauge... and yes the thermostat is out... well its in but i gutted the spring and everything its just a hole with a gasket now lol... and sorry if i confuse you... and do you have aim or something easyer to message/talk with?
