Hi Guys. Big problem with the radiator. I cannot get it to fix onto the chassis because the top hose is too long! If I engage the top hose the rad goes nowhere near the locating holes. I have gone over the video countless times right back to the point where the top hose is located in the engine. I have built and re-built the rad so many times it is unbelievable! Can anyone tell me what I am doing wrong?
