Replacing heater hoses to rear


On The Road

Recommended Posts

I just finished replacing the heater hoses going to the rear. I did not have a leak but the original metal pipe really looked bad. Not a bad job with all the side cowlings off and the cowlings are not that hard to remove. I also patched an exhaust leak. I used silicone 3/4" blue silicone heater hose. Kind of pricey, took two pcs 10 feet each. I did not remove the old heater runs just in case I have to hook them back up in an emergency.

Did you have valves on those hoses? Was just wondering because all the trucks I have driven have had a valve on both hoses, so you can shut it off if the heater hose starts to leak.

Did not have valves, all original. I probable should have added a shut off but did not. Would be easy to add one on each hose. Wish I had a shut off for the main heater hoses so I could shut them off in the summer. Might make the ac work a bit better.

If I could find the proper place to put a shut off for the cab heat I would install one. Would I need one or two shutoffs? I fully intend to do that. Has any of the other Volvos out there have a shut off for the cab heat and if so where is it installed?

I put one ball valve shut off right where the heater line dips under the R front frame rail, spliced it right in the hose w/clamps. I can reach it w/o opening the hood.

Wow. Thats interesting about only one shut off? There is a line that goes to the heater and one that returns. Every truck I have drove has a shut off on both hoses.

In the last few months I have had 2 heater hose failures, and have had to shut both valves off to stop the flow to make it back to the shop.

Maybe closing 1 valve off will stop the heat, but if a hose is blown you need to shut off both hoses? Or maybe they have check valves at the block for the returns?

Two shut offs are better ,it would save the coolant and a trip.School buses have a different priority - keeping the cab as cool as possible.

Depends what the goal is ,cool cab or keep on going down the road .Only two will allow you to keep on going .

A cooler cab only needs one.

Anyone with 1 valve better look again. The heater circulation is dependent on pressure differential, and a check valve will have a pressure drop across it, thus reducing flow. Cummins uses a 90* valve with a wire cross-handle. One on the supply and one on the return.

I have been wrong before, I'll probably be wrong again.

I have two lever style ball shut off valves for the cab and rear heater. They are located just underneath the air filter on the right side. They were easy to install and easy to get to if needed. I'd say it's a smart move...
