Hi all,
I have a rattle, noticeable when moving/squeezing either coolant pipes (see vid).
So recently:
*Car on ramps at the front so radiator cap is the highest point
*Leaking radiator removed
*Used radiator fitted, new coolant pipes also fitted
*Filled with bluecol 2y stuff, 50//50 mix
*Left to sit for a day, topped up, ran till at operating temperature with heaters on full blast and nice and hot
*Re-topped up
*Few days later out to get it test-ran, came back and still had air bubbling in the system as I could heat it gurgling (or water boiling.. :ohmy: ) in the engine itself (not the rad)
*Instantly get it up on ramps again, no overheating at the temp gauge, fan working fine
Come today, I've gone to check it over and noticed this rattle coming from the thermostat (I think).
This a fail-safe thermostat, that has done less than 100 miles since I fitted it 3 years ago.
Have I fried my thermostat from poor bleeding, or do I have a loose washer kicking about my cooling circuit..? OR is it simply the thermostat jiggle pin that I haven't noticed before?
The noise can be heard without much pressure, on either coolant pipe.
Cheers!
