Cam solenoid causing upper engine overheating??

No it wasnt the cheap dilapidated plastic man. It just seemed too hot.

Monitor coolant temps with a OBDII device such as an ELM327 hooked up to your phone.

If fan goes on to high speed at 105degC and lowers the temp to 95degC within 2-3 minutes (sorry not doing the F conversion; look it up) then all is well.

This is a great idea! I ordered a similar model on Amazon today. Being as the temp gauge on the dash is useless in seeing temperature changes. Much less Volvo really screwed the pooch by omitting a boost gauge! Apparently with the right app boost among other things can be monitored.

If a device like this can show real time fluctuations it might give the OP a idea what temp the engine is running at higher rpms running down the road. The block temperature at 140° sounds cool to me as my car's block was 180° like the head. Maybe my block is running hot? 40° is quite a difference? June

My car after all is fucked. And im too broke right now to fix it all. I just found out today that the thermostat i need is stuck inside a new complete thermostat housing for 170$! Cant just get the thermostat. Gotta get the whole housing unti! Thats how they get us. Anyway my motor runs hot. Oh well. Thats what internal combustion motors do. Thanx for the posts guys.

People have replaced the thermostat only in the later “ one piece “ housing,worth a search

Ok, the gizmo came and I downloaded the app recommend by the gizmo's manufacturer. I was shocked to see how well the cooling system handles heat removal. In my cars case; today I drove for better than a hour with ac on and the coolant temperature ran between 188.6° and 192° and even during a period where I drove hard 199° was as hot as the temp got and quickly dropped back to the 190° range. Attached is a photo of the $25 gizmo and a screen shot of what I selected to monitor. The app "Torque" was another $5. Dont forget guys if you want to order such a gizmo on Amazon to use the MVS link!

One thing I found interesting was seeing vacuum/boost on this car. With the two turbo chargers boost is instant feeling and now I know in fact it is physically. I also was surprised to see how high the boost pressure is at times. Also interesting to see the other sensors readings in real time. So $30 well spent! June

Ive since got new thermostat from junkyard. You can get the thermostat out of that whole housing and reuse it. I've had no issues with leaky metal gaskets it's been fine. I've since replaced radiator and flushed cooling system. Temps are same but all is well. This site and all of you on here effing Rock!

Volvo engines are tough! I sure am glad years later you still have your car and have fixed it. Mine is still running strong just shy of 200K now. June
