Hey guys.
Recently refitted my B4 with a closed deck block after its factory one died.
Replaced everything wear and tear in the process including new water pump and thermostat.
Have road tested it twice so far, once around town for about 30 mins and once on the motorway about 25 mins to work.
On the road test around town the bottom radiator hose warmed up somewhat, not as much as the top hose.
On the road test on the motorway to work this morning the bottom hose remained pretty much cold.
During both tests the temp gauge stayed stable at temp.
Is this normal or could there be an underlying problem that is going to lead to a cooked block?
The bleeding procedure I used was jacking the car right up at the front and filling it through the top radiator hose, Refit Radiator hose and fill through main radiator cap, burbed the top hose until no more air bubbles came out, started the car and burbed/bled it further until again no air bubbles came out.
Thanks in advance.
