Jetta has no hot air in winter and the water temperature is high.

Dear user, according to your description, answer the first question: the strange smell after changing the air conditioning water tank for the first time may be that the antifreeze residue leaked before was not cleaned, so a new warm air water tank was installed. Answer the second question: there is no hot air yet, and the water temperature is abnormal. It may be that the engine waterway or the large water tank is blocked. I suggest you clean the sewer thoroughly. Help you, thank you! Beijing Auto Repair Company's hotline: 800-8 10- 1384 Technical consultation email :jishuzixun@arcb.com.cn.
