overheating?
 

just finished swapping the ka24de into my 90 240 now its overheating..It slowly rises when i idle takes about 20 mins to atleast hit the C line then if i drive down the road it quickly goes up. I drove about 5 minutes to work this morning and it was close the the H line. Then driving home tonight again 5 minutes pulled into the drive way and steam was coming out of the engine by from the heater hoses...and clap wasnt on tight enough so i tighten it and its still overheating...engine ran fine and didnt over heat at all before i swaped it...what could it be??? Heater hoses on backwards? I have no clue :complain:

It isnt bled properly. Jack the front of the car up like 2 feet and then bleed it with the bleeder screw or through the radiator cap. The jacking up of the front is essential.

*edit* I could have sworn, on my mother's life, that I jacked up the rear of the car when I was bleeding my coolant system, but the internet seems to disagree. Maybe somebody can clarify.

Well i just drove it and it over heated in a matter of 5 minutes looked under the hood and there is a hair line like crack in my radiator and when you moved the upper hose steam came out and a little coolant. The upper hose is hot rad is hot and the lower is a little warm...i didnt jack up the front of the car when i drained the coolant but how do you bleed it properly after jacking it up? Just release the drain plugtill its all gone?

just drive on some boards or whatever to raise the front, take off your radiator cap, turn heat on all the way

add fluid until you can add no more and no bubble or nething are visible

also massage heater hoses to make sure its flowing good through the heater core

but the heat doesnt work at all..thats what i mean no matter how high the temp gauge says still no heat come out of the vents...

mine was doing the same thing i did everything bleed the entire system new thermostat and so i just removed the thermostat and it fixed everything so yeah give it a shot.

yea get a new thermostat, and make sure the fluid is flowing when u look inside the radiator, maybe your waterpump is doo doo

ok i drained all the coolant swapped the rad and it still overheated this time when i shut off the car coolant was splashed all on the inside of the front bumper and i tried taking he rad cap off and once i did a bunch of steam came out...i drove it not even 2 minutes up and down the road i just dont understand whats going on with this the motor didnt over heat or anything it worked fine when i swapped it...my gauge cluster doesnt work...the only part that works is the temp gauge any ideas?

I'm telling you, it's air in the system. You did swap thermostats right, or took yours out? Did you jack up the car when you were bleeding it?

yup i jack up the front of the car...and what do you mean swap thermostats? I swapped a whole motor and trans out of my car i didnt mess with anything like that..the car with the ka24de i put in my ran good...

After looking at it i noticed the lower radiator hose didnt have that sensor that isnt in the hose right before the radiator...i assume this can cause the problem? And where does that connect to the electric fan in the front of the radiator?

remove the thermo stat. if that fixes your problem. you either have a bad thermo or air in the system which isn't allowing the thermo to work properly.

Where does that connector in the lower radiator hose go too?

since when do we have connectors in our rad hoses? wtf

remove thermostat and your problems should be fixed.

lol thats what I was thinking.

THIS IS MADNESS!!!

you could try taking out your thermostat to help fix your problem... but it will actually cause the engine to take forever for the engine to warm up to operating temperature... so mostly just worry about getting all the air out of the system and making sure your fluids are topped off... also run your heater full blast while your topping off your fluid... hope you get some help out of this...

I guess i have to take a picture of what i mean... In the lower rad hose on one of my 89's it has like a harness going into a metal pipe in the hose...Anyway it isnt even in so im not sure if that made a difference...i bought a bew thermostat today so i think im gonna first try it without a thermostat then ill see what happens

sounds like one of those after market coolant temp sensors. i cant remember what there called. did you ever remove the thermo? or is the car just sitting or something?

Yeah before you put the new one in you should try to bleed the system with the old one removed, make sure thats the problem before you put the new one in.

Removed the thermo put housing back and such just havent run it yet ill be sure to do that tommorow. Now i found the screw with the yellow sticker near it that says do no open when hot. What exactly am i looking for to happen when bleeding it? Bubbles from where the rad cap goes...collant comes out of that bleeder screw i just mentioned?

The bleeder screw will bubble a little and when it stops releasing "foam" and releases coolant instead you're good.

guess i got a long way to go...once i put coolant in it it drips out from the bottom...

I know this is kinda out of place... but my uncles Hard body with the Ka is having the same issue.

Can someone take a picture of where the thermostat is... I would really appreciate it... This way I can help him out also.

the internet is your friend

Interesting...well i found out whhen im driving i leak coolant took a look at it again and coolant was trickling out of the front of the radiator so i have to replace that...after that its the whole process again...

Its a stupid question but do you have an overflow res. ?
