1990 Acura Integra

I have a 1990 Acura Integra and it recently started overheating. I had a friend look at it and he removed the thermostat and said it was bad. We didnt have time to put a new one on but we will do that next week. He put everything back together and since he did that, the car now leaks coolant. Immediately when I turn the engine on, I see a stream coming out of the bottom of the car on the passenger side. I checked the radiator hoses thinking maybe we didnt put one back on tightly but they are dry. I though maybe it was the water pump but I don't know why that would start leaking just from taking the thermostat out. I can't find the water pump to check that either. Any ideas on what could be causing this leak?

Hi biggs_charlie,

Overheating is usually associated with coolant loss. Before removal of the thermostat, there could already be leaking somewhere.

The water pump is located on the driver side. If it leaks, it has nothing to do with removing the thermostat, just that it was already was or has just gone bad.

Since you reinstalled the thermostat without replacing it, the gasket could be leaking after being reused.

Check the thermostat housing and the water passage pipe coming out behind it.

There are also the heater and bypass hoses to check.

Since it is leaking badly, you should be able to visually
find the source.
