Hijet Expansion Valve Hi. I have been crossing parts for these trucks for over 3 years now and the expansion valves have been a problem. Even from japan parts sources, which are quite expensive. I have been sent parts that are ALMOST the same but not quite! Also some of the ac parts are different for same year models. After extensive searching I found someone in Ft. Worth Texas who is extremely helpfull at anything relating to automotive A/C (thus the name of his business Extreme A/C Parts) What we did on Suzuki and Mitsubishi valves, Daihatsu should be similar, was send him our old expansion valves for comparison ( also the dryer.) So far we haven't been able to stump him. In each case we have had an exact new and inexpensive replacement part in 3 days or less. Not to be advertising for him, but he came though for us BIG time. You might want to give him a call or check out online. Hope this helps.
