so i just bought the car today i havnt takin the thermostat out cause i have no money to replace the seal yet. when its on the free way it doesnt overheat but when im driving in the city it overheats like on the way home it got just below the H and i stoped shut it off to let it cool down...any ideas my friend is having the same problem only mine doesnt spit the coolant out the overflow nor boil

 

Don't let the gauge go past half way! You're lucky if you haven't overheated the engine yet.

I wouldn't drive that thing until I had a Mazda Thermostat and Rad Cap on it (search for more info). Also, the thermostatically controlled clutch fan should have resistance to turning when the engine is warm.

 

as stated above, park it until you get the parts!!!! it could be something as simple as a t-stat or a radiator. those are the first two things i'd check. with that radiator check is the checking for coolant seal failure via alka seltzer like bubbles in the coolant when the engine is running. i'd then move onto the fan clutch.

 

k well i blead the radiator yesturday...it didnt look like alka selzer but it had a lot of air in the system and it wasnt gettin hot with the cap off. after i did that i put the cap on and let it idle for a good half hour then i drove it around for like 10 minutes and it didnt over heat or come close just stayed at 1/4 maybe i needed to drive it more or i fixed the problem idk....another question so i dont have to post another thread my brother thinks the oil sensor isnt hooked up but here are some pics at idle and at 2300 rpm


i think imma just save up and buy a new motor and get this one rebuilt and build it up

 

any ideas for the oil pressure? i think the guage is messed up cause when my friends fc is off it drops to zero not all the way down like mine...

 

well i just got the t-stat and gasket i got a Beck/Arnley t-stat and gasket...will it still over heat with that kinda t-stat....i know stant is crap

 

Im not sure if this is at all relevant, but when my oil pressure gauge went my engine followed about a month later. I dont think your is as serious though because my needle was like an inch under the 0 mark. Also believing me to think the gauge was just broke and it was just a coincidence that my engine followed it.

 

yea my needle is messed lol i was lookin at my friends and his didnt go down that far....
