hey, well i just got my car back from the shop, and im having a weird overheating issue, i just had a new mishimoto radiator put in.

so it drive it and it overheats, i try not letting it get into the danger zone then i let it cool down
but i need to get it from A to B !

when i touch the top of the radiator, it is super hot, and the top tube is really hot,

but i touch the front of the radiator, like the face, it is cool, and to bottom is even cooler.
the bottom tube is cool as well

i let the bleeder valve open when i filled it, but there is no hot air when i turn on the heat,

Im not sure i filled it properly
im guessing bubble or bad thermostat?

Anyones Input?

 

Still have air in the system. need to bleed it out

 

it feels like no fluid is being pushed threw my radiator, air could cause that?

if that is what it is i will search on how to properly fill the system.

anything eles it could be?

thanks for the input

 

Agreed

ill do it tonight or tomorow thanks for the help!

 

Try bleeding the air out, if that doesn't work check your thermostat. You won't believe how often a bad thermostat is the culprit of overheating issues. It was for me!

 

Most likely air in the system still.

 

ill try bleeding the air out, but compaired to the recomended way of filling her, i did nothing right i was to excited, oh well i learned.

and since my heater doent heat, i recon bad air bubble, thanks for input

 

ok so im bleeding the air out, and replacing it with fluid, like im squeezing the top and bottom rad tubes and bubbles are coming out, and playing with tthe relief valve untill only liquid comes out..

heater is working better, but im going to do it a few more tiems till heater is burning hot, and engine is nice and cool running,

thanks for you interest and help everyone

 

dude I change my radiator with a koyo V core ( I guess similar in size to the mishimoto)... if you bleed it right temperature won't go over 205 F after 30 minutes hammering on a road course with almost 100F outside...

 

I havent read the reccomendation but whenever I have dealt with pain in the *** cars with respect to air I've jacked up the side of the car with the bleeder on and it helps out a bit.

 

hey, everything is working out, what i did was let it cool, open bleeder valve, shouve a funnel into the fill port of the radiato and fill and when it comes out of the air bleeder, i put it back in,
and then i squeezed the in tube and out tube of the radiator and when the bubbles stopped coming to the top, i drove around and then let it cool then repeated, now my engine runs cool and my heat blasts hot

THANKS everyone!

 

i now consider myself an expert on filling/bleeding the cooling system
