i took my car for a drive today after 3 wks standing, had a overheating issue whilst it off road, but all fixed due to rad block

Thing is i took for a drive today about 4/5 mls on low boost, when i stopped smelt burning water smell put that down to soaking engine got, whilst doing flush,

Felt bottom pipe and still cold rad was hot, but pipe was as hard as nails, would this be the norm ?.

 

Sounds like a dodgy thermo.

 

Air lock?

 

Well must be my pace rad shot, modified my OE rad to fit, and all is well, temp to normal, fans kicked in and pipe is not as hard .
