No cabin heat, then blew upper radiator hose, cause?

Post by bob850 »

Recently bought a 1999 V70 T5, 230K miles, but it has a 2005 T5 motor (supposedly about 80K miles) and 1995 (I think) manual tranny with external slave swapped in also. Was told water pump was replaced with engine swap a year ago, but I don't know for sure. Was driving home from Los Angeles to Indiana, stopped here in Colorado to ski. Drove great all through Utah, and to Colorado.

Went to drive car this morning. Noticed I had no cabin heat, and it was about 10 degrees outside. Got a couple miles down road and heard a pop noise. Immediately pulled into gas station within 1/10 mile, shut car down, and found blown upper radiator hose, long spiral gash in hose. So what could cause this, besides a bad hose? Shop hopefully looking at tomorrow. They had a new hose and thermostat delivered already, but obviously need to determine root cause.

I was watching the temp gauge and it never rose above 3 o'clock, I'm pretty sure. The check engine light did come on shortly after getting on road. Also, the coolant light blipped on a couple time and went off yesterday, but the coolant reservoir was full, which seemed weird.

Any ideas guys?

I would put that down to a simple hose failure. Replace, refill, and motor on.

Get the motor to full operating temperature at idle and look fir new leaks, including inside the car at the heater core. You will have to pull some trim.

Is the old hose Volvo or aftermarket?

Don't know hose brand, but was supposedly replaced a year ago with engine swap. I suspect water pump failed since I didn't have any cabin heat just before the hose blew. Also, the hose didn't leak and rip, it blew big time with a giant spiral gash.

Also, the cabin heat was fine up to the morning of the failure.

The hose may have leaked before blowing.

The latest: Had shop clear codes (there was a low coolant code), replace hose and thermostat, fill with coolant, bleed, pressure test, had no leaks. Drove okay in town, but on the long drive home noticed the engine ran very rough when throttle is applied in upper gears (highway, 4th and 5th, over about 50mph), which it was also doing before the hose blew.

No codes have been set so not sure where to look now. The roughness goes away when coasting, even in gear, so it appears to be the engine running rough. The roughness is felt more when the suspension "bottoms out" in low valleys in road (with throttle applied). The seller told me he already install a Xemodex ETM, so it I'm hoping its not the ETM again. I'm probably gonna take it to my indy volvo shop and see what they can figure out.

How old are ignition parts? They last a long time on these cars so people neglect them until they fail.

I believed they were changed about a year ago with the engine & manual swap, but I'll look into it.

The Xemodex is intended as a permanent fix for the original ETM design.
The factory unit had moving parts that physically wore out. The improved
unit eliminates those parts in favor of a much better "no contact" approach.
