Dropped my son off at school and on drive home had sudden gush of coolant followed by steam on the passenger side below the dash. Glad my son was dropped off or he might had been scalded. Anyway, was able to get home and spend yesterday removing carpet and drying the passenger compartment. Before I assume the lotus position and investigate, any ideas of likely cause - this is my 78 S1? Is the weak point hosing or the heater valve? Also do you suspect I could tackle from below or need to access from within the front spare tire area?
Thanks

Well, take your pick. Heater, hoses, valve. Maybe a drop light and mirror or phone camera can postpone the Lotus position for initial investigation. There is probably coolant drips there somewhere that you can see.

Hi Rob,
I believe that you will have to attack the problem from the interior, and from what I have read, it takes considerable time and isn't easy.? I have postponed replacement of the heater core in my car until next winter as I am now driving the car four or more days per week.? My car came from Hawaii with the heater's water pipes short-circuited. If you get desperate and want to do the same, pic follows.? If you go this route, be careful of situations when you need immediate defrost.? Good luck!
Jeff, 139H

?Had this handy and I thought it might help as this would about be the positioning with you sitting in the driver seat considering left-hand drive and that fan far right is what protrudes into the spare tire area and actually the waterlines are just to the left of center in the car so I’m not really sure where coolant would spray out on the passenger side unless it’s got a leak in the heater core may be and spraying out of the shroud somehow but yes investigating with a probe and looking for drips essential.

Sometimes the easiest answer in an old car is the previous owner.?

When I looked under the dash I found a right angle tube installed with no hose clamps. A ticking time bomb which luckily went off near home. Lesson is I need to go over the whole car make sure nothing else was overlooked like this.?

Glad it was such a simple fix.

My life is just full of coincidences lately. I just sold my 73 Mustang to Monterey Touring Vehicles ?Rentals. My JPS Esprit came from Monterey in the 80’s.
