Zc In Heat!!

OKay OKay... I need some help here people.. i have a ZC motor, just freshly swapped about a month ago.
Yesterday morning the heater in my car was only getting warm.. NOT HOT. That afternoon i was driving home and the car started to over heat so i pulled over and turned it off, then started it again and it was at normal temp until about 4th gear and it overheated again. it did this all the way home so i ended up rollin home at 20mph.
I called the mechanics and talked to all my friends.. they said it was the thermostat.. so i replaced it this morning.... No Luck... it still overheats and now the engine light comes on..
Also i have a new water pump.. and a new radiator.. i dont know what else it could possibly be.. and now the air in the car doesnt heat up at all, its just blowing cold air.. if that means anything.

:bloated: this is how i feel!

I really wish I could help but I was gonna say your thermostat...but now I really wanna know wha it is...hmmm. Good luck!

did you replace the water pump and radiator yourself? if so did you bleed the cooling system...there might be air in the cooling system casue the coolant to dissapear which in turn causes over heating.

To bleed the cooling system, follow the upper radiator hose to where it connects to the engine. You see a lil thing like a bolt with a hole in it. loosen it and fill the cooling system until it flows out of that with no bubbles. Then tighten it and fill everything to spec.

To bleed it you can also just take off the radiator cap when the engine is cold and turn on the car and let it bleed itself.

Could be something wrong with your heater core?

My DX did that then the head gasket blew and the head cracked.

It could just be your thermostate. Does the upper rad hose get hot after the engine is warmed up? If it gets hot then the thermostate is ok. If it wont get hot then you need a new thermostate, only a $10 part.

If your thermostate is ok then it could be you head gasket. If thats the case dont drive your car or you will screw up the head like I did :(

Make sure its bleed thats what it sounds like to me.

it could also be your coolant temp sensor.

I flushed the coolant system and noticed a loose ground on the injectors and on the thermostat housing.. now it runs perfect!

:devil: time to go burn some rubber!

Hehehe... Thats great! How do you like that motor VS the stock one? I have a D16A6 in my car now (swaped it in about 4 months ago) and a JDM DOHC ZC in my back yard :devil: But Ima rebuild the whole bitch before it hits my engine bay! Im lookin at spending $3000-4000 on the motor before it hits my car! ALL MOTOR... I have a seriouse itch to show these "B" ass mother fuckers whats up with the OLD SCHOOL!

Hell yeah dude, ZC is killer! I should've done internals on mine but it was really a spur of the moment swap.
Now i can keep up with B16's with no problem!

Realy? You meen 2000 SI's right? I meen a B16A in a 88-91 would smoke you right?
