over heat

[BUSHWHACKER]

Rad cap housing? Do you mean thermostat or the actual housing ,what could be wrong with that? I had the same problems as you, changed Tstat and rad cap and all was fine for 1 week and now eratic temp ,cold blowers again.

Definitely an air lock. Top up coolant and leave rad cap off overnight to let the air escape. Re-check level in the morning and top up if necessary.


Leave rad cap on driver's seat so you don't forget to re-fit it. Set both heaters to hot before topping up.

I had one the same, ended up taking the whole rad out and getting a new top, put on.
You could hear the pressure leaking out around the cap and a slow bubble in the overflow bottle.
