Any recommendation on what type of oil to use? I've seen 5w30, 0w40, 10w40 recommended.. I'm a bit confused on what would be the best to use. I know it has to have the ACEA A3 certification but that does not really narrow down what weight of oil I should use. If it makes a difference I live in Canada in a relatively cold climate but the car is only driven in the warmer months, perhaps as low as 5-10 degrees on the colder spring/fall mornings.

I could write a long post, but I'll keep it short. I'd normally suggest 5W-40. If your climate is cold,you might be OK with a 5w-30, or 0W-40 in the winter. What are your temperature ranges winter and summer?

Thanks! Also, the smaller hose that comes off to the side that goes to the check valve, do you know if that can be replaced with silicone hose?

The only hose I don't suggest you use silicone for is that hose from the nipple, to the check valve and then onward. Silicone will weep oil in that location. I recommend oil/gas resistant hose for that one. BUT, I will note that a lot of folks here have used silicone, it's weeped, but it's been fine.

You'll probably break the check valve in that line when you start moving it around. Most are old and brittle. You can use a generic one from the local parts store, etc. Saab sold the lines and valve for $30... you don't need that.

Temperatures in the winter range from -20 to 5 degrees. In the summer it's usually around 15-30 degrees. All depending on the day..

And you called breaking the check valve once I started to move it around. Looks like it was long overdue for a replacement anyways. Also the vent hose that comes from the cover seems to be very soft and also due for a replacement.
Unfortunately the small hose that goes from the nipple to the check valve also cracked. This is the one I plan on replacing with a silicone hose.

What are the high temps in the summer and winter? Are those temps
F or C? I guess if those are celsius , those could be the ranges Summer and Winter?

I'd use 0-40 in the Winter. Summer I'd use 5W-40. Acea A3/B3 rating required.

Yeah, sorry I never clarified that it was in degrees Celsius. The temp changes pretty drastically here over the span of a day. That's why there's such a big range.
Thanks for the recommendation, I'll go with the 5w40.

I just did the PCV update on my kids car. It looks like yours has it. I would get some 5/32 vacuum hose from you local parts store and replace all of the vacuum hoses. You will need about feet worth.

I personally use 0w-20 in my Saab's.

Just for info, 5W is good up to -35°C. Of greater importance is to use full synthetic oil and regular oil and filter changes depending on the mileage and driving habits.

Do88 makes a Silicone version of the PCV hose kit.


I saw that too, but i was under the impression that you dont want silicone hose where petroleum comes in contact?

 

[jvanabra]

There are processes to treat silicone to handle petroleum. Regular silicone vacuum hose doesn't have those treatments... Theoretically the do88 stuff does.

You would hope so based on the cost.
When you look at the cross-section there is a small fabric weave between the layers.
I have the Do88 PCV kit and coolant hose kit on the majority of my hose setups.
So far I've been impressed with the quality. I've had the coolant versions for about 5 years, and the PCV for about 3.

 

[Saaberachi]

Good to hear! I just ordered the do88 coolant hose kit & thought about the pcv kit to. It would be nice to find a complete #6 kit in silicone.

So does that mean you are guessing it does?

Personally I do not know what the benefit is to using the silicone version. The rubber version works great and last about 70k before it starts to crack. It also seems to seal better to the fittings imo.

Silicone hose lasts longer, is more resistant to heat & comes in pretty colors! Lol i bought new rubber radiator hoses 1 yr ago & the ends are already starting to bulge & feel thin. The 90° end on the one heater hose is prone to bursting. Ive been on the side of the hiway from this b4. The silicone kit shoukd prevent this

The oem saab/gm pcv update hoses are ok but dont waste yourtime & money on the pps or uro versions

Ive never tried silicone for that application but i found a volvo in the yard that had blue silicone hoses on it with pretty large one way valves plumbed in. Idk how long they were on there but i didnt notice any deterioration at all

Canadian Tire has house brand 5W-40 and 0W-40 (OE and OE Plus, I think respectively) They are A3/B3/B4 and will be under $30 on sale for five litres.

Unless you are going to drive a whole lot, you are likely to do one oil change a year. Your car may or may not use oil; if it doesn't, one 5L jug will do you for a year. If it does use oil, well then inexpensive synthetic is the thing to use.

For my 2004 convertible (different engine, but similar oil change principle) I would change the oil last thing in fall, so it sits over the winter with fresh clean oil.

I don't know anything about the do88 hoses, but they tend to make quality stuff and it seems unlikely they'd leave that box unchecked.

I am very satisfied with the factory parts and haven't felt any inclination to spend the money on fancy hoses, so I'll likely never know what the story is.

I put a PPS PCV 6 (lines were brittle) on my 06' 7 years ago and they are going strong. At the same time I did all new coolant hoses that were all PPS or URO (which ever ones I could find) and no issues with them. I am not a huge fan of PPS normally, and I am not saying they are as good as the factory hoses but my 06' has over 200k on it and they are doing quite well. The only hose that has broken twice on me was the MacKay coolant bypass hoses. They suck.

I would have to see some test info on silicone to show me they are worth the investment.

I also see no reason to use them.

 

[Saaberachi]

Every piece of rubber that had PPS on it that I've ever seen was a dilapidated piece of crap, whether it be 6 months old or 6 years. Glad you are getting better results

The other issue I had is part availability. The Do88 hoses are designed to fit, come with matching clamps, and were available in Aust. Agreed I could have also sourced the PPS versions. I’ve been replacing old hoses wherever possible. Both the PPS and Do88 versions are fit for purpose, however in my mind having a new set of Do88 has given me confidence- particularly with the coolant hoses.
