ok, so i was riding today when i came across a slow driver in the pass lane, i got a shot at a pass, took it. i passed him but with a price. My coolant light came on, and then the smel and steam. its cooling off right now. it didnot over heat, just lost alot of coolant, i was close enoughf to make it home.
what i need is a diagram of the coolant system, i lost my vadis download a while back when my vista took a turn for the worst. I know the turbo is water cooled also, tommorrow i will be collecting CSI style evedence of the crime. Just want to make sure i hit all the points. Im sure its the lower hose due to massive wetness in the area under the air intake hose, lots of steam there, and a little steam around the area closer to the radiator. the whole under side of the car on the drivers side is soaked.
any help or advice is truly apreciated. :o :blownose: :blownose:

How long since you replaced it? Why go through all the trouble when you can just replace an old hose and get new clamps? I havent replaced my lower hose since I got the car... who knows how lond its been down there? :unsure:

:haha: Shawn of the dead!!!!
well, the same hoses was used to save cost during the rebuild. i will replace both upper and lower hoses tommorrow.
But is ther more to it, thats my concern, the turbo is water cooled, its still to warm in ther to feel it out. gotta wait. I hope i didnt blow a turbo cooler line. :puzzled:

ok, got to the real problem. A BLOWN HEATER HOSE!!!!! any advice or instructions on how to fix that? im on it.

Repairing a heater hose (or any high pressure coolant hose for that matter) is a false economy because, if it has blown in one place already, there is no guarantee it won't blow in another place after being repaired (and then usually when least expected).

Why not buy a new heater hose and fittings from a supplier such as FCP Groton or similar.

I know I would, even if it was for no other reason than peace of mind.

Wheres the off topic posting, I got something to say, see you there.

:clap: good advice, but really out in left field :haha: . Any true mechanic knows to replace all hoses at the same time. That was my point :blush: , but when you spend over 5,000 for a new powerplant some times things have to be left out, now mind you i keep up with all maint-lists and procedures, nothing has been missed but a coulple of small things, but my 850 had a good start, got all paperwork and times, full dyno, and time slips.
Guarantee? Whats that? I drive a volvo :lol: . It keeps my skills up. But i overly enjoy it. :thumbsup:
I like FCP and Ipd, hell i buy enoughf from them, but if i can i rather buy dealer, more expensive, but puts money back to the ones responsible for all the fun, Volvo International. :thumbsup:
Plus i really love the new Volvo Mechanic Bachlors Diploma i have hanging in my office. After this magazine I will Open my own Master Shop, preformance based of course. :thumbsup:

Just a thought, feel free to ignore it.

But there must be a reason WHY the heater hose blew up in the first place. Was it simply deteriorated due to aging? Or was the thermostat stuck-closed?
Or something else?

I have learnt the hardway, that even though chances of it happening is small, a stuck-closed thermostat can cost you a new engine. *sob*sob* And mind you, i USED to purchase ORIGINAL VOLVO 93dgrees thermostats, and i change my thermostats every year without fail. Now i go for the lower 87degree OEM ones, and still will change it every year. The cost is amost one-third of the blardy Volvo ori ones.

:)

Cheers.

when your thermo gets stuck what happens every time? Overheating most usual and definate boil over. One way to tell if the thing gets stuck is to wait for the temp to get at "running" level. Warm..... watch the overflow tube, is it flowing thru it and not the main hose? thats tell tale. the hose opening burst was very close to the engine half of the hose, the hose was the original, or a used one from a donor. I would assume the hose was stabbed while being reinstalled at one point. But however, you are right that "something else" may happen if the hose was perfect, but, if that was so, then the core or any one of the quick connects or even the seals on the fire wall would have failed, in conclusion, with help, the hose was weakened due to care and common sense.
Since fixing the issue, to the date no leaks, or over heating, and the level moves as it should. I just feel the hose was ready, like a radiator hose does, fail at the best time.
But... your advice and opinions are greatly wanted and needed. Every answer is valuable and gets put on my permanent to do lists.
THANK YOU ALL!!!!!
