Terrible Heat

Just posted a tread on a head light issue, but I am also getting terrible heat, unless I let the car still idling, but as soon as I start driving it again the temp goes does and almost no heat.

I was thinking it might need to burped, anyone have any how to's on this?

Thanks

Update:

The car just popped the Check Engine light, 2 codes P0115 & P0128, from what the guy said it is the thermostat and the engine coolant temperature sensor, makes sence to me.

I am going to replace both but... They only have the thermostat and not the gasket, any ideas on where to find?

What is good brand for volvo sensors, anything online?

I want to do them both at the same time so I only have to open the system once

Really can use a service manual if anyone has one.

I bought the therm Friday from the dealership and replaced it on Sat. Everything is working great now, heats up nice. Besides a scan tool is there any way to reset the CEL? I had the battery off for about an hour, thought that might reset it but no joy. My local auto store has a policy of not resetting the CEL with there tools and I really don't want to go to the dealership just to reset the CEL. Thanks for any help.

Bad thermostat would indeed do it. Glad you fixed the problem on your own!

Pull off the battery cable, go around and press on the brake pedal or turn the ignition to start, and then reconnect it. If the S40 computer is anything like the S70, it will go through a bit of 're-learning' where the car will idle/shift weird, etc., but it will go away soon.

Thanks, I'll try that.

Yea, that didn't work or I have another code that is popping the CEL immediately

Reading the codes again will tell you much more than guessing what's doing it!

Well, the saga is finally over, the CEL turned itself off after driving about 150 miles. Glad it was just the thermostat, and I have to say it is easiest thermostat change I have done, not that they are hard unless just a PITB.
