hiya guys, I recently bought my first supra (93 NA SZ Jap import) and have ran into some problems which I was hoping you could help me out with. The car was running fine for the first 2 weeks then on a hot day when I had been running the car all day, I saw steam coming out of the engine (note the temparture guage was reading as normal), a few days later it happened again and I discovered the coolant hose at the back of the engine which connects to the heater core had split, the engine had then started misfiring and running rough, so I removed the house and reconnected the other one so that it bypasses the heater matrix. I had noticed a lot of water had leaked from the hose to the engine, so checked the spark plugs which were drenched in water, so dried it out and replaced the plugs, the engine was no longer misfiring but still overheating (but this time the temp guage was high) so I flushed the coolant system and eplaced the thermo stat and compression tested the cylinders which read lowest 174psi highest 184psi cold engine, I also checked for signs of gasket failure in the oil and coolant. Yet it continues to overheat with the coolant resovior boiling and spraying water out, and light steam at the back coolant hose. Thanks for anyone that took the time to read this and offer any suggestions as I'm all out, and I'm ssorry for the use of paragraphs and grammar as I'm on my phone that freezes.
