We have been having some overheating challenges - be fine on a run to the store, hit about 3/4 max on the way back; periodically belch coolant. I think I have had two problems:
One problem is that the overflow side tube at the top is an aftermarket fix - one of those plastic jobs that may have interfered with the cap motion - Seemed as though the rad wasn't using the overflow to either dump excess or draw down to refill. Blelch when overheated, run low on fluid and heat up after(?) I have just now trimmed this down so hopefully all good now - I know, should get this brazed on...
One problem could have been that I didn't properly burp the system - but I believe I did... twice... also tested fan clutch and seems just fine.
Here is the interesting bit: I went to flush the coolant and ready for my replacement thermostat (due here Monday) and realized that the PO had removed the thermostat - there was none.
General reviews of removing thermostats are all over the place - fine, takes a long time to heat up; not fine, need the restriction in the system to work properly; save $5 and that can help pay for a new head later - etc...
Anyone run, internationally or accidentally, without a thermostat? We are 15 degrees C/59F here, have not actually overheated, but clearly running hotter than it should,
thanks
