Over heating issues

[MIGGZFSU]

Hey guys

OK so the first drive I took with this car the radiator exploded

Then got the radiator repaired and installed

Cleaned out the pipes and noticed no thermostat so left it out

It's got the stock fan but no cowling


If the car idles no issue but when I drive for more then 4km it get hot and really hot.

I flushed the system, looks like the waterpump is flowing can see the water movement in the radiator and both pipes from rad are warm and stiff

What's the thoughts

put a thermostat in would be my first point of call.

Considering the car is overheating already the thermostat won't help... got to be something else...

Do you have a proper radiator cap that pressurizes the system? Or is there an open connection to the overflow bottle?

Also did you properly de-air the system after refilling?

How stiff are the water tubes? Sounds like a possible headgasket / cracked head block issue.
There's a reason someone took out the thermostat, most likely to temporarily cover up overheating
issues.

Hey guys will go through now what iv done to date

Water pump flowing

No water in oil or oil in water, no smoke

Bled the system correctly

Cap on radiator is functioning

Did a pressure test on the system then took the spark plugs out and cranked the car no water coming out there

So I have ordered a thermostat

Going to install that, if no luck I'm going to connect up the electric fan and see, if still no luck I'm parking the car off for a while

What kind of set-up are you running? Oem engine, oem radiator etc? Oem bumpers? (Because of airflow)

Also could it be running lean? I know this causes higher exhaust temps but not sure to what extent this has an effect on the temp during idling.

Does your car still have the automatic transmission installed?
On my Carina I have the A40 automatic transmission that uses the radiator to cool the transmission oil as well. It could be the case that the combination of both is too much for yours.

Yeah still auto and using that combo

But everything is still stock?

and when im driving the car is at night and its like 10'c here
