Hi, My name is ***** ***** for the delay.
I will do my best to assist you
first,if you havent already,install a new radiator/reservoir cap,a cap can give a fit when bad..
next,sense the cooling system has been worked on,there may be air still trapped in the engine..lets bleed the system this way
1-remove the radiator/reservoir cap when the engine is cold
2-start the engine and let idle
3-turn the heater on max
4-keep coolant on hand and add it as needed
5-some coolant may gush out with the air
6-keep doing this until the engine is at operating temperature and the heater is hot
7-after the coolant settles down and the engine is warm,,install the cap
This may take as long as 20-30 minutes
if it still overheats after you do this and if the engine ever has been really hot,i would think it has blown head gaskets and they will need to be replaced
thanks
