I just swapped in an L26 with L32 heads and GenIII blower. The motor only has 25K on it. The motor runs fine except that it doesn't cool down. It has no problem warming up, it just doesn't even slightly cool down. The coolant is full, new 180* thermo, no leaks, 25K on the WP. I've bled the system so there shouldn't be any bubbles. Does anyone have any ideas? I'd appreciate some quick answers since I need my car back on the road.
