Should you remove the oil cooler lines on your P80 car? My test results, Volvo 850, S70, V70 etc.

In this video I share my experience and results of the oil cooler lines that go to the radiator delete mod. My results show that they are not very effective and there is no harm in removing those expensive leaky oil lines and blocking them off with a NA plate.

You are welcome

Revisited this posting again to copy the link and spread the word on another forum. My pile of spare houses out back is growing; I'll take them off a freshly acquired T5 tomorrow.

Thank you Robert!! My 855r has no oil lines because of your help, it runs great too:)🙏🙏

Thanks for the detailed results on your oil samples and temps. I'll be deleting these lines on my 1996 850 Turbo wagon very soon.

[@RobertDIY]

Cool

Good afternoon Robert 😊 great video on deleting the coolant lines and data from samples 👌 Thanks for sharing 👍

Are they 400hp 850rs?

[@babyhuez597]

I just had both my lines rebuilt about 3 weeks ago. I paid $165 for upper and lower. Wish this video was out before I had them done!

[@RobertDIY]

Don't install them. Sell them to someone. ;)

[@babyhuez597]

Robert DIY lol. No ones gonna want them after they see this video.

First sign of those hoses leaking - they will be removed. I've had that area leak on me before and it is a PITA to get those torx bolts out. Those and the lines will be replaced upon any leakage. Great update Robert!

[@mattj456]

Thank you for your time and research on this! Could you post the part number for the block-off plate and gasket? Do parts suppliers carry them or better off pulling from a junkyard?

[@babyhuez597]

Matt Jones I concur

[@RobertDIY]

Give me 10 minutes. I'm sure the parts are on a parts website. I also showed the part with the part number on it. 🤷🏾‍♂️

[@KevinBurmeister]

Did you by chance find that part number? I plugged in the number I could read off of the video and it came up as nothing.. I appreciate it!

[@KevinBurmeister]

The parts just went back in stock at my local dealer. 'Cap' part number 1366780, gasket part number 1366791.

[@dawnrobbins5877]

Very interesting! The Mobile 1 oil is really good stuff, apparently. I wonder if other brands would produce different results?

[@RobertDIY]

Probably not. Most current full synthetic oils cam withstand a lot of torchure.

[@850are2]

I removed mine too. Maybe ill report back in winter when its -20 with results of the oil “warmer” condition.

[@RobertDIY]

Ok

[@Shieldapr]

Nice

[@RobertDIY]

Thanks

[@fortis6215]

Thank you for the informative video. Question. Looking at the oil cooler line thermostat, which line is the oil return line to the engine? Does the oil travel to the cooler via outside line and return back to the engine using the inner line?

[@RobertDIY]

I have no idea. What difference would it make? I'm getting rid of both of them.

[@RobertDIY]

You can pull the lines or disconnect them from the rad. Start the car and go see which one is pumping oil out.

[@fortis6215]

I’m adding an oil accumulator and need to tap into the return line. I tried running the engine with both oil cooler lines off and, surprisingly, oil poured from both lines. I’m baffled.

[@lesdmark]

Mine were deleted when i got my car and i had been trying to figure out a way to reverse that. I guess that's one less thing to worry about then!

[@RobertDIY]

I can get you a reversal kit. 😅

[@RobertDIY]

If you plan to do some extreme driving you can add the system back but run the lines to an external cooler.

[@tiktiago]

Hello Robert, I have a V70r Fwd from 1997 and when I bought it I noticed that the oil coolant lines were deleted. Since I knew that these mixed radiators sometimes they mix oil with water, I installed an external oil radiator. Now my question is... The coolant hoses that came from the oil radiator are never worm or hot. is it possible that the thermostat is not workin properly? Can it be something else or is it normal? Thank you

[@RobertDIY]

What's the temperature of the oil?

[@borcestanceski4889]

Thanks for your video bro... I lkke to make some power modifications so i think that i will need oil cooler, so i think about to put one from alfa gtv with radiator not temperature exchanger...?

[@RobertDIY]

Ok

[@HandMadeWrath]

@robert diy can you do a engine harness removal video? Or just ahow the locations.

[@RobertDIY]

I did that a couple of months ago.

[@HandMadeWrath]

@@RobertDIY a link maybe?

[@sjbock]

So, if I understand correctly my 94 850 NA doesn't have oil cooler lines so I don't have to worry about replacing or removing them?

[@jessewildman1292]

Correct

[@RobertDIY]

What Jesse said.

[@blake8me]

im a liitle late to the vid but wondering.. Can you just leave the connections on the radiator open? no oil is pushed out? may be a dumb question but im about to do this job and curious. Thanks

I’d be curious to see if results were any different with a do88 radiator.

[@RobertDIY]

ship me one and I'll test it for you. ;)

[@pachucagomez7970]

Hi Robert, I tell you my experience, I bought my 98 v70 awd with the cooler lines canceled, it was always my doubt if this affected something, the previous owner explained to me that the radiator broke down and I mixed the water with the oil, and for that reason they canceled the cooler, I consulted with a volvos mechanic and he told me that it is not usually a major problem that I do not have it for city use or normal use, so I left it as it was, now I have a question with which can you help me, what is the normal operating temperature of your volvo? mine is usually between 93 and 104 C, it has coolant and the system has a new water pump and a new radiator, the needle on the dashboard is always in the middle, what could you observe in your Volvo on this issue? thank you very much Robert! Regards!

Not sure what setup your 850s had, so just want to confirm this would be safe to do on a C70 T5 2.3 Turbo?

[@RobertDIY]

If it's a '98, yes.

[@juular1565]

@@RobertDIY yes, 1998. Thank you for the great information, I've now ordered a blanking plate.

[@mecheng1977]

Are the existing bolts the correct size?

[@RobertDIY]

I don't understand your question.

[@mecheng1977]

@@RobertDIY I mean are the existing bolts on turbo cars with the thermostat the correct size and length for the cap? Also can you not leave the lines abandoned if you find a way to tie them off?

[@benjaminmellingen5340]

I think I have some leaking oil coolant lines on my 95' 944 (FK). There isn't any lines going to the radiator, but I think there is a housing where the oil filter screws onto the car with two lines going to it. Do you know if this can also be deleted? It looks like this: www.volvopartswebstore.com/images/parts/volvo/fullsize/GR-68614.jpg

[@RobertDIY]

I would not. Takes no time to replace them and they are cheap. 🤦🏾‍♂️

Is there a part number on this block off plate?

should be in the remarks section.
