Overheating!! Help!!

[sPoOnD_]

hey guys, i have a b18c block b16a2 head, just had it rebuilt last week and now its overheating, if i keep under 70km's its ok but once i go over the heat climbs up like never before :S any ideas? the top radiator hose is like a balloon after ive driven it.

[bennjamin]

clearly the radiator is clogged - get it changed / checked asap

its a brand new one, just changed it

[bennjamin]

its a brand new one, just changed it

its clearly not flowing. Blocked thermostat or blocked radiator somewhere work out the issue asap before you fry the engine !

would it be like head gasket or anything? i changed thermostat too :(

-try opening the radiator cap, start the car and see if continuos bubbles occur if it is, possible headgasket problem
-wens the last time u changed ur waterpump?
-check for any leaks whilst car is running,
-is the top radiator hose a balloon and the lower radiator hose cool?
-wait for the car to cool down and flush the fluids out, see if the coolant is still the same colour.

hope some of that helps

also let the car cool down on its own slowly without adding more cool water etc, helps prevents blowing a headgasket

water pump is brand new, changed it when i got it rebuilt,

both hoses r like balloons

and no leaks



but there is black stuff in the coolant ( exhaust gases )
i think the head mightve lifted :(

Hey man sucks to hear about the over heating right after you got it rebuilt.
Was the job done by a good shop?

Two things about the head, aluminium = easy to warp and not just a hassle to put on.
Assuming they're second hand parts ask if they were checked for warps and cracks first, and if the head was removed from another engine just a curious point for me would be to ask how they removed the head (if you just straight lift the head without removing the bolts in a correct sequence you'll warp one side pretty easily).

I'm guessing if they would have checked it then they would have machined it so I wouldn't really ask them unless they tell you they checked it.

Uhhh, only other thing I can think of is to buy a head crack/gasket test kit (detects if there's internal combustion gas in the cooling system) might help you at least narrow it down ^_^

Good luck man

Maybe do a pressure test from the radiator
