159 2.4 new head gasket, running hot
Hi everyone, hoping for some more expert advice. First of all a big thanks to Ed for his advice on my cylinder head. I took it to Thurstons Engineering in Ongar and they did a great job, couldn't fault the service.
So the problem, I purchased my 159 2.4Ti a few months back, it had overheated and needed a new head gasket. Head gasket fitted, head skimmed, valve clearance adjusted to match, new water pump, belts and thermostat, oil change etc. Sounds awesome, purrs nicely. Only having taken it on a few test runs and cleared out any air pockets in the cooling system I noticed it is definitely still running hot. It gets to 90 very quickly, it doesn't go over 90 but it doesn't drop from it either regardless of how its driven, I could imagine it going over if I really pushed it but I'm not willing to try. I've had a 1.9 16v GT and an 8v jtd 147 and both ran at around 80, sometimes less but rarely above unless driven hard or in congestion. So I'm assuming its running a bit hot.
Having bought it with the head gasket blown I don't know what the original cause for overheating was, was it the gasket that leaked boost into the coolant first causing it to overheat or did it overheat causing the head to warp and then leak compression? I don't know. But its definitely not leaking compression any more since being put back together, the thermostat and water pump have been replaced and the cooling system has pressure in it with no leaks. So what else could it be?
When I took the bumper off I noticed this damage, I'm not sure what this is, I think its the air conditioning condenser, either way it looks hammered! Loads of damage, could this affect the running temperature? Maybe the radiator behind it is the same, I should imagine it must of been taken out by someone at some point for it to get this damaged, is there any way of testing the rad without removing it? I have already run coolant from top to bottom and it got through no problem. I have attached some pics, any advice would be much appreciated
