Default overheating

my 91 1.8 with link & avo turbo overheats.3/4 on the meter. I have a larger radiator. (Godspeed.)
Thermostat opens. Coolant fresh. No leaks. Fan running controlled by link ecu. Only when driving slow. Highway no problem.
Could it be timing related?

I am using the oem 1.6 coolant system on the 1.8. Waterpump is new, radiator new, cap new. I always thought the engine is low on power. So my timing could be off. (harmonic balancer fail)

as for the timing: if the crank is at tdc is the pulley mark on 0? Got my engine build with a 99 crank in 95 block i used the best looking pulley. I also must say that its hot today.

Pulley mark at 0 when TDC. With the link there is a procedure to set to 10 BTDC. I found with the Godspeed and 2 Ebay fans that I wasn't getting enough airflow. Try adding another fan and/or do some ducting.

If your godspeed radiator is really thick you'll need another cooling fan. I second ebay slim fans. I went for the 2200cfm flavor.

My stock fans works on my thick radiator. You need ducting.

It's the big godspeed (52mm)

So if i add the ac ventilator (parallell) the problems must be gone??
Or do i need ducting too?

With ducting you mean the front or the splash pan??
I still have the original black ducting in the "mouth". The Splash pan is long gone...(due to ic routing) I could hack it up and place it back...

How about a coolant reroute?
