I just replace the radiator water pump and the fan clutch oh yeah and couple of hoses here and there and cleaned out some hoses that were clogged by the heaters core I think basically did all I知 thinking that is connected to the cooling system am I leaving anything out well anyways it does well when I知 driving normally but yesterday it was 97ｰ here in town 5 o団lock traffic no sooner than 20 minutes from work to my 97 starts to overheat I manage to get out of traffic drive a little bit and the temperature went down weird so I知 guessing that it痴 just it basically Has to do with some kind of airflow or water flow issue I知 stumped I check the water level and it seems to be OK Well anyways is there anybody can help me out I hope so thanks for listening

 

does the heater work? if not you got a clog

what temp is it getting up to?

 

Also make sure to run a 180F thermostat

 

It痴 possible that there maybe an issue with a head gasket. Mine started out this way and it finally failed. I知 not a D1 expert but this is just my personal experience.

 

Maybe get a cheap scanner that reads the engine temperature. That is more accurate than the dash gauge.

 

Also check for debris between the condenser & radiator
