So I recently blew a heater hose (intake manifold to heater valve) luckily only 2 blocks from my house and was able to limp the car back home without the need for a tow truck. This was wake up call for me to inspect and replace every single coolant hose on my '93 daily driver with 220,000 miles on the clock as a preventative maintenance. The last thing I need is to get stranded on my dreaded bumper to bumper, 97 degree weather, 30 mile commute to work in Los Angeles. I've already replaced the upper and lower radiator hoses and all the heater hoses using a mixture of molded and generic flexible heater hose, but I was wondering about the TB coolant lines:

1. Anyone know what size hose the TB coolant lines are? (I'm afraid to remove the old hose and destroying it in the process only to find out no one in town carries that size hose!)

2. Can I use generic flexible coolant hose without routing problems or stick with the molded stock hoses (if they still exist)?

3. Does the "TB Bypass" mod really work? Will this MOD fail a visual inspection for a smog test in California?

4. Any tips to remove the dreaded driver side TB coolant line without destroying something else?

5. I think I covered all the coolant hoses- upper and lower radiator hose, heater hoses, TB "water bypass" hoses, radiator overflow tube. Am I missing anything else?


Thanks in advance.

You can replace the driver side one with generic stuff
The passenger side is molded I would look into sewell parts or cross ref toyota

Looks like 3/8 or 5/8s

Since you are replacing, just disconnect from the upper hose side and pull it out with the long hose attached

I would just replace the hose at this point it is not hard
There is also a heater hose from back of valve cover to the pass side heater choke thing
