What's your timing set at, both initial and full?
Does it overheat while you're at cruising speed or during stop and go city traffic?
Do you have an air conditioning condenser or transmission cooler in front of the radiator? What type of electric fan do you have?
How hot is the outside air temperature when it is overheating?
What pressure radiator cap do you have?
What ratio of water/antifreeze are you using?
These questions may help narrow down the issue.
I don't remember what the timing is at. I had my US-friend set it for my - but my "number-list" (don't know the english word) on pulley dosn't seem to be right. I put the piston 1 at the top position, with the head off and it says 10 degrees at the pulley. Now we know this when the motor is put back together.
It overheats the most when I'm cruising. I stay FAR away from city traffic :-)
Yes, I have a transmission cooler in the front. But it's put as far to the right as possible. It dosn't block for the air flow - if that was what you were thinking :-)
I can't remember the name of the electric fan. But it's bought in the US as one of the most powerfull ones. There are no doubt, that this fan does the job great. It pulls SO much air through the radiator, that I can put my hand on the radiator with the water at 200F, without burning my fingers (on the outside, in front of the fan). When it gets hot, and I stop the enigine. The fan cooles it down in 5-10 min.
The radiator cap says 1.1 on it. I haven't ever had it to.... What do you say.... Go off? :-) But I have "shot" the radiatorhoses several times with a laser termometer, to see if the gauge is off. But both the gauge and the termometer says allmost the same.
I mix water and antifreese 50/50 in the coolingsystem. If that's what you mean?
The temp. here in Denmark dosn't come over 86F.
