I recently got a s13 with a dohc, and I knew It had some issues with overheating.
Symptoms:
Drives longer than 45 mins and the temps start to rise. But the temp drops pretty quick after.only happens at low speeds, interstate is fine.
Overflow has boiling fluid after a drive or once I turn the car off, you can still hear it gurgling.
No heat, very few times will the air from the vents be hotter than a cool breeze.
Felt the top hose one time waiting for it to stop overheating and it was swollen and bulging
Things that have been tried:
Compression test- within range
Thermostat
Bleed the cooling system numerous times and the correct way
Water pump
I was told, and assumed it was a headgasket at first but no signs of milky oil, compression is solid, pulls strong and doesn't smoke at all.
I'm thinking a possible block of a coolant passage of the heater core blocked.any ideas ?
