I have high idle and my car is running rich. about a month ago I replaced the vacuum lines and all seemed good. That was before I got hit and since then removed the head, block, and all that. Maybe some of the vacuum hoses have since been torn or broken since then. I'll replace them for good measure. The question I have is the hoses that connect from the intake manifold. The coolant ones. I have done a lot of reading to suggest that they get clogged and contribute to high idle and the vehicle running in cold start mode causing rich burning fuel. When I touch the hoses they seem warm, but not hot. I'm thinking I should replace them too. If I replace them do I need to drain the coolant out of the system? Or just expect to get coolant everywhere? Also, would getting a coolant flush at a shop yield the same results? |

I've used pure white vinegar to flush cooling systems. Drain the engine coolant. Save it if you want to reuse it. I use and recommend the Toyota Pink coolant, premixed from the Dealer. http://geometroforum.com/topic/4724846/ |

Not Really All That Smart

Since those hoses are part of the cooling system, pulling those hoses will result in air entering the system, which is bad. So if you want to also do a coolant flush, now is as good a time as any. If you don't know when/if it was done before, then it's cheap maintenance and something that will expand your knowledge base and also be good for the car. All coolant jobs are a little messy. There is really no way around that. You're going to spill some stuff. If you have a clean pan (or some old apple juice containers in my case) you can catch as much as possible and dispose of it properly. But despite what everyone says, you're going to end up letting most it drain into the driveway and drying in the sunshine. Don't waste money on a fancy nozzle or anything. A water hose and your hand as a sealer will do a fine job. I always remove the thermostat, put the housing back in place and flush from the top and then from the bottom. It's easy, like everything else on these cars. |

Thank you all for the information. After opening the hood and bending over I realized this task is a little too much for my back to handle. Not being in good health is limiting my ability to work on this vehicle. Any idea how much a shop would charge to change out the hoses and clean everything? |
