1980 244 HEAT

Jtreehorn · Post by **Jtreehorn** » 09 Feb 2005, 10:47

The cabin climate in my 1980 244 runs from warm to blistering, with nothing cool to speak of. As it's the middle of winter in Seattle, excessive heat is a great asset and nothing to complain about, but I'm concerned that come summer time I'm going to be hanging my head out the window like a dog trying to get some fresh air.

On the plus side, my engine temperature stays nice and cool (unlike my '81 244, which necessitated opening the heater all the way to vent the overheated engine). I know these old Volvo's get pretty toasty, but is there a chance something needs to be taped or fixed in order to get some cool air scooped into the cabin?

Thanks.
Nick

I suppose you have the following problem, it is very hot, then you reduce the temperature just a little bit lower, and suddenly it is totally cold. The valve used for the adjustment of heat is rather "advanced". It has also a thermostate and when this thermostate function is broken it will be either cold or warm. You have to change the water valve for the heater. Volvo does not have the origin valve any longer in stock, so Volvo will offer you a rebuiling kit with new rubber hoses and the same valve that is used in the 740 series. Then you have to cut and bend som plates. This rebuiling kit is expencive, so try to get some copy. In Sweden the price for this origin kit is more than 100 USD and probably you will have to pay much more over there.

Wow, really? I figured that fixing the climate control would be a pain in the butt, but that sounds like something I'm willing to tolerate for the time being until it gets too hot outside to stand it.

THanks!

Actually it is quite easy, The valve LaRy speaks of is the valve where the coolant hoses connect to on the inside of the firewall, simply replace this valve with one from a 700 series and your problem should be fixed

That doesn't sound like too big of a hassle, does it? There's a terrific Volvo boneyard in town were I should be able to pick up a 700 series valve no problem. I'll check it out this weekend and let you know if I get cool air flowing in to my 244DL!

I have a 93 240 sedan in the USA. I had the problem where I the heater was constantly on. Like the other posts suggest here, my problem was the valve that connects the water that cools the engine to the heater core that supplies the heat for the cabin. I had it professionally replaced (2 hours by a mechanic; the 93's are apparantly in a wierd place) and the problem stopped immediately.

Note that I took the defective valve and blew through it with the valve closed and no air got through. I concluded that the valve may not have been the problem, but rather the problem was the cable that connected the control in the cabin to the actual valve. My point is to make the cable secure - it also effects valve performance.

PS having the heater on in the summer does suck!!!
