Some pictures of the old rad. When I removed the old rad I stripped it down and for one noticed this huge gouge on the front fins and second it was plugged with crud.
Jay has two cars a lot like our X1/9s, same designer, same coachbuilder. Follow his advice starting at about 3:55 in this video.
If it is able to hold 190°F under load, I would not suspect the thermostat. When you say the temperature is creeping up, does it keep going up, or does it stabilize at bit above 190°F? Or fluctuate a as the radiator fans cycle on and off?I just had her out for a drive and found that while driving the temp stays at 190 but when idling it creeps up.....any other ideas??
I was thinking thermostat....
The fans kick in but the temp still seems to creep which makes me think it’s the thermostat. It doesn’t get anywhere near where it was getting with the stock rad but it’s my understanding that the temp should stay at 190 regardless.
Help!!
Ok, good to know. I just happen to have a laser temp gun so that’s some good advice.
JimD, when you used your manual fan did you see any change in temp? I think I might wire my fans to a manual switch as well.
I just may get a new water pump as the cost is quite reasonable and switch it out this winter.
I suppose while I have the system drained I should change the thermostat at the same time. Although, after reading a bit on the other threads I don’t think the thermostat is malfunctioning as a bad one would cause almost immediate overheating with no stabilization...
