Oil in Coolant/Antifreeze

[awd1stdsm]

I had my coolant system flushed last week. I checked the level today and its very low plus, all the coolant is a nasty brownist/green cooler. It this a result of a blown head gasket only? Or there anything else that could cause this? Temp gauge says the car is not hot but, when i opened the hood after 10mins of easy(no boost) driving it was differently hotter than normal. Motor is stock 134k 91' AWD

Thanks

Its most likely rust and calcium deposits

I'd fill it with straight water & check for leaks first. Thermostats & hoses don't seem to like being "flushed' so I'd change T/Stat too - If you have ANY original Coolant hose on that '91 the hose is BAD - period - It's possibly the well documented but sadly widely ignored internally cracked Water to Oil Cooler / POS - Sucks but better than a HG - which is ALWAYS a possibility... :thumbdown

Is there anyway to block off the cooler? Will any 1G cooler work as a replacement?

also, car does Not smoke at all during driving.

Of course - bypass the Coolant Lines going to the "waffle " Cooler - but you'll have no Oil Cooler - You need to backfit an Air to Oil Cooler - see my Gallery for pix & there are numerous Threads.

How do a bypass the coolant going to the cooler?

What all/else do i need other than the cooler lines etc. to swap to a 90' air-oil cooler setup? Hope to pick one up from the junk yard.

You'll see the small Coolant lines to & from cooler - literally install a jumper/bypass.

At that point you'll have NO oil cooler - personally I would definitely run Synthetic Oil.

Maryland can get cold so IMO you would need a 90 Oil Filter Housing being it has the Low Oil Temp Oil Cooler Cutoff Valve built into it unlike our 91 OFH & any small Aftermarket Air to Oil Cooler.

- OR -

- Buy an Aftermarket Low Oil Temp Oil Cooler Cutoff Valve AND Aftermarket Oil to Air Cooler plumbed up to your 91 OFH (see my gallery for pix of adapters & hoses). Then you can cut the longer threaded portion of your Oil Filter Bolt off - throw the Water Cooler away - Loctite the long threaded portion into your 91 OFH & slap your oil Filter straight onto your 91 OFH like a real car & NEVER spit an Oil Filter gasket again...

Our DSMTUNERS Vendor/Sponsors have all this stuff & there are many threads on this you can Search up.
