So my radiator was replaced because the old one blew. But it gets hot when the car is getting pushed somewhat hard and then takes a long time to cool down. I bought it about a week ago from a buddy of mine and he said that it’s just cuz he never bled the lines. So I did that, but it’s still having the same problem. I’m pretty sure it’s not leaking because there’s no drip anywhere and the levels haven’t gone down. Could I have not done the bleed properly? Or is there another issue that could be?
p.s, she doesn’t over heat if you drive her normally, but when I wanna push her she gets very hot after acouple minutes

 

Are your fans working properly?

 

Try bleeding the system again and if you keep having that issue, consider doing a pressure test. Just be sure you don't have any leaks in any coolant hoses.

 

Make sure both fans are spinning properly on HIGH SPEED, The fans will be in low speed when it's up to temp and requires little cooling. You can force it into high speed by turning on the AC, have someone else turn on the AC while you physically WATCH the fans spin to make sure they both kick up to high speed.

You probably have a fan that's either not working, or not turning on high speed properly.

Possibly a small coolant leak that's not allowing the system to build pressure but you will typically be going through coolant when that happens, either dripping or coming out as steam and instantly evaporating.

 

So I bled the system like two more times and that seems to have worked. She’s not overheating anymore at all really. Thank you

 

These cars are a pain to bleed. I'd recommend getting either the Z1 or the CZP aluminum bleeder port. The OEM plastic ones are garbage.
