Cooling system problem
Hello all,
I have a problem! It seems my cooling system is no recirculating the liquid.
Last Friday (2019-09-27) the radiator in my 2000 T4 broke.
I replaced the radiator last Monday (2019-09-30) and today proceeded to go about my business, only to find out the car was over heating.
When I replaced the radiator I thought I had removed all the air in the system, and apparently I did. It was overheating and it was not being able to cool down.
After a few minutes I realised the car was not sending hot air through the vents.
I tcheked to see if there was a blockage inside the heater core but no, there was none.
Just in case, I bypassed the heater core , and there was no change, the car is still overheating and not able to get the temperature down. It starts climbing and I eventually have the turn the engine off.
After this a proceeded to testing the thermostat, and it opens, but just in case I removed it.
Has expected, the car took longer to get up to temperature, and after the fan kicked in, the temperature kept raising, although it was hovering at around 101ēc longer then before, but it might have been ambient temperature related.
I tcheked for air and I pretty sure there is none.
The lower radiator hose is cold witch could make sense if the cooling circuit is from the upper radiator hose to the lower one, although with temperatures above 100ēc I would assume the hose would be hot, although less hot then the upper one.
Do any of you have any ideas??
I'm puzzled and don´t now what else to do.
It is has if the circuit is not circulating.
Help please
