Subject: Re: Overheated at the drive through Zoo by djxib on 2009/7/24 12:49:04 A couple of things: The radiator is definitely worth looking at. Years of crud can build up on the surface and it is worth taking out and carefully cleaning the outside of the radiator(not an easy job but worth it). Check that there isnt any junk trapped up between the radiator and the AC heat exchanger. As far as the temps, I agree that it could be the sensor or bubbles in the coolant. Have you experienced excessive coolant overflowing into the plastic tank? If so, could be as simple as the radiator cap (surge tank cap) not holding enough pressure. For the erratic idle - possibly a stuck IAC valve or vacuum leak. Spray the engine with MAF or TB cleaner while it is at idle and see if you can prompt any surging. In terms of parts, I would 'personally' pick up the following: - Radiator cap - coolant temperature sensors (both, water pump mount and passenger side head mount) - IAC valve - Coolant hoses (have been known to fail / collapse - Maybe a new accessory belt (1992's are double-sided and hard to get sometimes) - a new 383 shortblock Actually, just kidding on the last one :-) Good luck! Where in the UK are you? |
