So I stopped the car in the garage today, and had the hood popped to check a/c refrigerant, and lo and behold, something starts spouting off like a geyser. Way too hot to get in there, but I could see coolant spraying off of the turbo on the intake side - it almost looked like it was coming out of the turbo itself, over by the intake, but I know that can't be because there's no coolant circulating there, right? Any guesses? Unfortunately, it doesn't leak when it's cold, and when it's hot, I cant get to anything to look at it.

This sucks.

 

Hmm...pulled off intake and found this: possibly the heater core lines that are leaking?



They feel a little "gooey" for lack of a better word....

 

Could be the heater hoses or the supply or return for the turbocharger. Get a coolant system pressure tester so you can pressurize the system to find the leak when it isn't hot.

 

Got the coolant system pressure tester.....that didn't take long to find the leak - a little tiny hose (about 6" long or so) that appears to come off the back of the block and connects to the turbo. It has a right angle (almost) in it, and it was a giant pain in the rear to get to, as it was tucked behind the heater core hose. Anyone know what this hose is for? If it matters, it's a 1994 855t with a 16t turbo on it.

 

its the turbo inlet cooling hose.
Its a common popper, I know 4 people not including you who have had this happen in the last week.

Its a easy fix from underneath.

Volvo 850 Parts | FCP Euro

The dealer should have it for around $7

 

Closest dealer is about 90 miles from me...lucky me. Have to see if i can find something that will work at advance.

 

Where are you located again?

the only problem is that the ends are different sizes..

If you order it from Fcp and pick priority mail you should have it by thursday

 

Yeah I'm screwed.

 

fix this problem before your car over heats. the same thing happened to my friend and he would not get a new hose but tried to do some adjustment without replacing the hose all together. he ended up with a shot head gasket.

 

Just called around, nobody down here has a spare, alan (tech) is going to look at work tomorrow and let me know.

 

I got one ordered...who knows when it'll get here. I opted for priority mail delivery, so hopefully i see it Thursday.

 

I guess I'll order 2 and change them on both of my cars. I think all hoses should be replaced before the car is 15 years old. Just not worth the risk.

 

am planning to change all my hoses before summer hits us. just to be on the safe side. my hoses are all stock.

 

I too am going to be doing some "while I'm in here" type things - namely changing the heater core hoses as well. They look kinda gooey, for lack of a better term. I'm probably just going to do the cheat with the 5/8 heater hoses from heater core to block.

 

am going silicon hoses, they last longer.

 

Slim: in all liklihood, i won't own this car the next time the standard rubber hoses need to be replaced, so I'm not spending the extra money for silicone. The original hoses lasted 19 years...who knows where this car will be in 2032...

 

Lol, that's the real deal. If you think that you will only need it for another year or two, just use anything. If you hope to have it another five plus years, get good hoses.

 

rspi: I DID order the genuine Volvo hose from FCP...and I doubt that anyone even makes the block to turbo inlet hose in silicone....90 degree turn in it, about 8 inches long, and each end is a different size.

 

What was the part number on that hose ??

 

6842190 is Volvo part number.
