HELP. Desperation, last resort before scrapping Project 16v.

When cruising normally there isn't much of a temp change from top to bottom of the rad?

IIRC the (stock)thermostat on the 16v doesn't open below ~81-85ish so there would be no flow through the rad at 80.

Temps seem to be within limits to me but I would check for sufficient airflow through the rad. Normal driving should be more than enough to cool it down to around 80.
