Hi Guys
I have searched and searched this forum but nobody has mentioned anything like this lol.
I have a lexus is200 auto 1999 on LPG , ive owned it since 2013 and it ran beautifully before i parked it up in dec 2018 due to using another car. Before i parked it up in 2018 i remembered that the passenger side vents stopped blowing hot air and was cold air only while i got hot air at the driver side vents. Also radiator would make bubbling noises but never had a leak or over heating problem.
Just had the car MOT'd last month and felt like using this as its a auto and on lpg so cheap to run. Couple problems highlighted :
1) Radiator bubbling, white small bubbles in radiator once engine starts warming up, coolant reservoir good to go. With the cap off the radiator and engine warm alot of steam comes out of the cap, once cap is closed the bubbling gets really loud almost as if someone is hitting the RAD with a wooden stick.
2) No hot air blowing through any of the vents inside the car even with the engine warm and air con temp up.
3) When i do turn on the vents when the engine is warm in side the car all i see is STEAM, yes STEAM pouring in from all the vents and all the windows steam up like mad.
4) I have driven the car with aircon/heating off except the bubbling in the radiator no problems even with car at warm temp, ive also driven car with engine temp warm and vents open and the car steams up inside and the car leaks all the coolant and i cant seem to see the leak from the engine bay but the water drops from near the inside of driver side tyre if that makes sense
What i have done so far :
I park on a steep hill facing upwards, removed both rad and reservoir caps, turning on heating on low fan high temp and let it run for 30 mins while pressing the rad pipes and occasional rev, still the same problem occurs.
Any of you experience guys and gals give me any pointers about what it could be (also car has never over heated to red if that helps)
Thanks guys
