79 overheat
 

hello ,

i have 79' 2seat overheating problem i change the water pump and the thermostats i check with the fan its working fine but the heat meter is in the middle some times go up little bit i didn't clean the radiator

Make sure the Temp sensor in good working condition.( xenon/s130.com )
That is a good idea to clean or replace the Radiator!
Also Timing will play a roll on overheat issues.

Welcome to ZDriver! :006:

A super easy way to see if the radiator is working correctly is to use an infrared thermometer and measure the coolant temp at the upper radiator hose, and the coolant temp at the lower radiator hose. There should be a 25*-30*F drop.

thanks folks ,

i will try to measure the coolant and let you know

My problem was the radiator fan clutch when my z was overheating.
