mrsmackpaul Posted December 13, 2022 Share Posted December 13, 2022 Usually means compression is getting into the cylinders Head gasket would be the likely cause, maybe the compressor but not likely as it normally needs heat and compression to cause this to happen Paul Quote Link to comment Share on other sites More sharing options...
Adkat Posted December 13, 2022 Share Posted December 13, 2022 So nothing came out drain but system was full, right? So is the drain plugged with snot from inside the cooling system? Seen systems with enough crud in them to block an inch line, so radiator cores would be definitely blocked. Which would cause the pump to cavitate, creating air bubbles in the system. Wrong mix of coolant/ anti freeze can react with each other, as well as poor quality/ hard water can cause corrosion/ rust in system. Just something to think about. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Joey Mack Posted December 13, 2022 Popular Post Share Posted December 13, 2022 When you had the thermostat out, did you take the belts off, and run the engine to see if bubbles are present? you can also bypass the air compressor coolant lines in order to rule out a failed compressor head. If you do this and bubbles are present, I would say bad head gasket(s).. If the bubbles go away, hook the compressor lines back up and check for bubbles again.. If bubble show up, then the air compressor is bad.. jojo 2 2 Quote Link to comment Share on other sites More sharing options...

Adkat Posted December 19, 2022 Share Posted December 19, 2022 Spot on Joey, seems like Mike can get this sorted without having to take it to a workshop. No bubbles with belt off sways toward pump cavitation from blockage/ foreign matter in system, as does nothing coming out drain on cooler. Nothing that couldn't be fixed by pulling a few hoses and back flushing. Also some good cooling system cleaners out there worth a look at. Worst case pull the radiator and have it rodded . See how he gets on. 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted December 19, 2022 Share Posted December 19, 2022 I like the idea of a coolant flush.. an old timer taught me years ago to use Cascade.. It was for oil, however,. It cleans.. Jojo 1 Quote Link to comment Share on other sites More sharing options...

Adkat Posted December 23, 2022 Share Posted December 23, 2022 I've used this with pretty good results with rust in systems. https://costeffective.com.au/product/rmi-25-cooling-system-treatment/ Don't know if you have a similar product over there. Anyway, any news on how Mike's getting on? Quote Link to comment Share on other sites More sharing options...
Moparmike Posted December 24, 2022 Author Share Posted December 24, 2022 ok guys I said oil cooler it's the transmission cooler that runs off the bottom hose on the radiator my apologies I haven't had much time to really mess with it but I'm going to have to make so.e time I really appreciate you all Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted January 4, 2023 Share Posted January 4, 2023 Gauge readings look good at idle... Thermostats are easy to replace on that. Quote Link to comment Share on other sites More sharing options...
