Well - turns out the threads on the cap were stripped, expansion tank as well!

Replaced both with parts from dealers (Chico, CA and near Sacramento).

Engine still heats up so I jumpered the fan but may have been too late, at the last stop I saw coolant leaking underneath - likely the pump gasket.

I'm still 15 hours from Las Cruces so will try to find an Indy tomorrow morning, may end up leaving the car & getting a rental to be there by Christmas.

Does anyone know a good Indy in central CA west of Modesto?

Thanks

Leaking or dripping? Where is it dripping from? Near the radiator or waterpump?


Hottest I got.

Mike...how fast is it leaking? If it's slow you can roll it by carefully watching the coolant level and topping off every couple hours. If it's leaking from the pump, you need to think about doing the timing belt job since the pump is driven by the timing belt

Have a peek in the Mechanics Forum to see if anyone has posted up something there

Hi,

If the relay is the problem you could probably just replace that.

In a normal relay circuit if you jump the relay it just means the relay cant turn the device (fan) off anymore. With these cars though i dont know what the computer might sense. If it worked though it must be ok.

Another option is if you can disconnect the fan and then jumper directly to the fan, that would be a direct wiring positive and negative.

I think you should check to see that the fan NEVER runs first though, under any conditions. It should run at least part of the time after the engine heats up. Never did a comprehensive test on mine though as to when it runs and when it does not run.

Happy holidays :-)

The coolant leak could be turbo coolant hoses x2:

All - sorry I dropped this thread. Here is the Reader's Digest version:
I did replace the fan relay at the dealer in Sacramento. Fan still did not seem to work so continued with the jumper wire. Got most of the way through LA to Pomona, CA. Stopped for gas just before 3:00 and looked under the hood - to my utter frustration coolant was pouring out from behind the TB cover! Drove the car across the street to McDonalds - my new forward operating base ...
Started making calls (based on Google) found an Indy in West Hollywood. He was the only place to answer the phone (keep in mind, it was 3:00 Friday afternoon - day before Christmas Eve). Mike, owner of Volvo shop, agreed to look at the car after Christmas. Called my auto insurance to get the tow, called for a rental car, called for a taxi to Burbank airport for the car. By about 9:30 that night I was back on the road, driving a convertible Mustang - only car left (for price of compact) in torrential rains headed east out of LA. I stopped at a hotel overnight, made it to Las Cruces, NM 7:00pm Christmas Eve.
Mike, shop owner, came down to his shop on Christmas Eve to pull the V70 into his shop so it wouldn't get broken into. The water pump gasket had split. the pump impeller was fairly rusty as well. Mechanic speculated it was the original pump (car has ~ 184,000 mi).
Cost me just under $700 for that job, plus the car rental & flight back to LA to get it. Tough lesson to learn. I had been chasing a coolant leak that I assumed was just the hose from expansion tank to thermostat, leaking back behind TB cover. I had also replaced every hose (including 2 turbo cooling hoses) except the heater hoses.

After all this the car still seemed to heat up & have coolant level issues. We drove it up to Albuquerque, NM Jan 3rd before finally flying back to Seattle, WA. While there we contacted Robert (DIY), just a day or so before his health issue surfaced. Great guy - just as helpful in person as he appears on YouTube. Robert checked compression and told me we may be seeing a pinhole leak in the Head Gasket ...

My son has since returned to Las Cruces, he is a student at NMSU. I left both the V70 (which he owns), and my 95' 940T which he and I drove down in August.

I'm still debating which car to sell, probably cut our loses on the V70 and give my son the 940.

I still very much like Volvos, especially when I have to replace the thermostat on my Audi A4 (mounted on the block - whose idea was that??). But next Volvo I buy will be very well screened, and include a background check of the owner ...

Sorry to read about your not so perfect ending of that christmas trip...
I'd drop the v7p over the 940T if you
a) don't want to have the head gasket fixed and
b) don't want to drive the 940 back home to WA (which i understand after that experience)

Leave the Volvo in school until he finishes then make the call. You can also bring it back one summer and do the head gasket over long time.

Abscate - that is something to consider. Have to admit I do like the V70 GLT. I had an S70 GLT same model year - 98' That was before electronic throttle, has normal oil filter & no variable valve timing. Unfortunately we need the money to help with his tuition.

I'll start another post about both cars.
